    Abstract: Morphological and chemical studies of Hypogymnia from the Himalayas revealed one new species, three species new to the region, and a previously unrecognized synonym. Hypogymnia crystallina, distinguished by its rimmed holes in the lobe axils, a pruinose disc, POL+ epihymenium, and distinctive chemistry (zeorin, hypoprotocetraric acid, usnic acid and atranorin) is described as new. Hypogymnia pseudohypotrypa (Asah.) A. Singh is synonymized with H. thomsoniana and a second location is reported for the recently described H. sikkimensis. Hypogymnia bitteri, H. mundata, and H. subarticulata are reported as new to India. A total of 17 species of the genus Hypogymnia are accepted for the Himalayan region of India and Nepal, with one additional species from southern India. A key is given to the species known from this region.

    Abstract: This is the first comprehensive summary of the occurrence, literature references, and ecological context for lichens in any state or province in the Pacific Northwest or northern Rocky Mountains. Because we also include reports from adjoining states and provinces, the book should be useful in a broad area. The monograph will be an invaluable reference for people delving into crustose lichens. So far, a total of 1074 species are documented from Montana. Of these, 283 species are new for the state and 19 are new to North America. We discuss the rare, threatened, and endangered lichens of Montana. Priorities for surveys and monitoring are evaluated by placing species in one of eight categories, based on all combinations of global rarity, ease of detection, and habitat vulnerability.

    Abstract: Hypogymnia papilliformis McCune, Tchabanenko & X. L.Wei is described as a new species of lichenized fungus from the Primorsky region of Russia and Shaanxi Province in China. It is a relatively rare species from mixed conifer-broadleaved forests in suboceanic climates, in mountainous areas at elevations of 600-1500 m. Most similar to H. delavayi, the species are distinguished by branching pattern and chemistry. Hypogymnia papilliformis is predominantly isotomically branched while H. delavayi usually develops subpinnate branching. The ceiling of the lobe cavity is mid brown to dark brown in H. papilliformis, while the ceiling is often pale brownish or white in H. delavayi. Also, H. papilliformis lacks 3-hydroxyphysodic acid, and thus has a K-medulla, while H. delavayi always contains 3-hydroxyphysodic acid as a major substance and is thus K+ slowly reddish brown. We provide a key to the six esorediate Hypogymnia species known from the Russian Far East. © 2015 British Lichen Society.

    Abstract: We inferred phylogenetic relationships using Bayesian and maximum likelihood approaches for two genera of lichenized fungi, Hypogymnia and Cavernularia (Parmeliaceae). Based on the combined ITS and GPD1 dataset from 23 species (49 specimens) of Hypogymnia and two species (8 specimens) of Cavernularia, we conclude that Hypogymnia is paraphyletic, and that it should include Cavernularia to retain its monophyly. Hypogymnia hultenii (?=? Cavernularia hultenii) and H. lophyrea (?=? C. lophyrea) are accepted here. Five species of Hypogymnia represented by more than a single individual were found to be monophyletic and significantly supported. The phylogeny reflects a statistically significant biogeographic pattern where continental-scale endemic taxa tend to occur within the same phylogenetic group. Sorediate taxa, which have worldwide or broader geographical ranges than affiliated species lacking soredia, are spread across the phylogenetic tree. Hypogymnia contains three species pairs: H. krogiae and the sorediate counterpart H. incurvoides, H. minilobata and the sorediate H. mollis, and H. lophyrea and the sorediate H. hultenii. In the case of H. minilobata, both members of the pair are restricted to a small area in southern California. In the other two cases, the fertile counterpart occurs only in North America, while the sorediate species occurs in both North America and Fennoscandia. This suggests but not proves an origin of each species pair in North America, with migration of the sorediate member to Fennoscandia following the prevailing wind direction.

    Keywords: Alaska/ Community assembly/ Denali/ Disturbance/ Fire/ Functional traits/ Growth form/ Lichen/ Photobiont/ Vegetative dispersal
    Abstract: Abstract Questions Popular methods to analyse community–trait–environment relationships constrain community patterns by trait and environment relationships. What if some traits are strongly associated with community composition but unrelated to environmental variables and vice versa? We take a different approach, unconstrained by this assumption using non-parametric methods. We applied this technique to lichen (fungal/algal and/or cyanobacterial symbioses) communities across environmental and fire age gradients by measuring richness and cover of four important functional traits: energy generation (type of photosynthetic symbiont), water relations (inferred from growth form), dispersal capability (from vegetative propagules) and microsite specificity (measured by substrate affinity). Location Denali National Park and Preserve, Alaska, USA. Methods We ordinated plots in species space and regressed trait and environmental variables against ordination axes, resulting in one- or two-dimensional trait and environment surfaces. We then superimposed these surfaces on the ordination to create a new visual display, the ‘hilltop plot’, which enabled simultaneous measurement and display of one- and two-dimensional, non-linear community–trait–environment associations. Results Most traits examined show non-linear relationships with community structure. Fire favoured simple cladoniiform lichens, species with higher vegetative dispersal capacity and specificity to grow on wood, but excluded the ‘reindeer’ lichens, which had lower cover even more than 20 yrs after fire. Forests had more sorediate lichens than non-forested habitats, whereas high elevation, rocky areas had more green algal and fruticose lichens. Cyanobacterial lichen richness was positively related to shrub cover, while tripartite (cyanobacteria and green algae in a single lichen) and foliose lichen richness was highest in areas with higher moss cover. Conclusions Different combinations of lichen functional traits peaked along environmental and disturbance gradients, which we interpreted as balancing energy generation, water relations, vegetative dispersal and habitat specificity. Our method of trait–environment–community analysis revealed numerous one- and two-dimensional, non-linear relationships between community composition and functional traits, environmental variables and fire age gradients, which informed mechanisms behind community assembly. Our results indicate non-parametric and non-linear methods of trait–environment–community analysis have the potential to detect patterns that would have been missed using current popular techniques.

    Keywords: Alaska/ Gates of the Arctic National Park and Preserve/ growth-form/ photobiont/ vegetative dispersal
    Abstract: Lichens in the Arctic play important ecological roles. They also face the threats of increasing fire and shrub and tree expansion, exacerbated or caused by climate change. These forces may lead to changes not only in lichen community composition but also in the abundance, diversity and distribution of lichen functional traits. We sought to connect landscape-scale patterns of lichen community composition and traits to environmental gradients to both monitor lichen communities and clarify community-trait-environment relationships. We measured lichens throughout one of the largest and most remote U.S. National Parks within the Arctic. We then analyzed lichen community composition and species richness within ecologically informative lichen trait groups along environmental and vascular vegetation gradients. Macrolichen species richness in 0.4 ha plots averaged 41 species with a total landscape level observed gamma diversity of 262 macrolichen species. Jackknife estimators placed the landscape level macrolichen diversity at 307 to 331 species. A gradient from low-elevation forests to high elevation rocky areas was the dominant ecological gradient as expressed by the lichen community, representing 68% of the variation in species composition. Low-elevation forests hosted more epiphytic lichens characteristic of boreal forests, whereas high-elevation lichen communities were characterized by saxicolous lichens, varying between siliceous, basic or mafic rock types. Along this gradient, species reproducing vegetatively and lichens with filamentous growth form were more frequent in forests while the diversity of traits was highest in alpine habitats. Simple cladoniiform, as opposed to erectly branched fruticose lichens in the genus Cladonia, were the only functional group associated with tussock tundra. Vegetation types differed significantly in lichen species composition and richness and trait richness; characteristic suites of lichen species and traits are associated with the particular vegetation types in the Arctic. We also extended the range of Fuscopannaria abscondita reported new to North America and Zahlbrucknerella calcarea new to Alaska.

    Keywords: Lichen/ Cladonia/ Usnic acid/ Spectral/ Rangifer tarandus/ Forage/ Mapping/ Landsat 7
    Abstract: Spatial variation of available food resources can be difficult to accurately quantify for wide ranging organisms at landscape scales. Lichens with usnic acid, a yellowish pigment, constitute a large portion of caribou winter diet across much of their range. We take a new approach of modeling lichen abundances by capitalizing on unique spectral characteristics of usnic acid lichens. We utilize a recently completed ground reference vegetation data set extending over 12,000 km2 in Denali National Park and Preserve, Alaska to model the abundance of usnic lichen and other forage vegetation groups. Spectral signatures were obtained for more than 700 vegetation monitoring plots in Denali from Landsat 7 ETM + imagery. We fit models of the absolute percent cover of vegetation groups corresponding to caribou diet items, with a focus on lichens. We used non-parametric multiplicative regression to capture the non-linear relationships between vegetation cover and spectral and environmental data. Different groupings of lichen cover were tried as response variables in addition to usnic lichens to see if other lichen color groups were more detectable. The best fitting lichen model was for usnic acid lichens, which explained 37% of the variation using only three predictors (elevation, bands 1 and 7). Elevation had a non-linear, double-humped shaped relationship to usnic lichen abundance while bands 1 and 7 were positively correlated with usnic lichen cover. These results support previous spectroradiometric ground measurements that indicated usnic lichens were distinctive at those wavelengths. Other vegetation groups had models that explained between 31% and 51% of the variation in cover. Maps of estimated abundance of usnic lichens and other vegetation groups covering the northern half of Denali were generated using our models. These maps enable the study of the role of food resources as a continuous resource in winter habitat selection by caribou, rather than assuming food as a coarser, categorical or thematic variable assigned to discrete areas of the landscape as has been done in most previous studies.

    Abstract: Biological soil crusts are ecosystem engineers in arid and semi-arid habitats; they affect soil chemistry, stability, and vegetation. Little is known about regional variation in biotic crust communities of North America. We explored how biotic crust lichen community composition and richness are related to vascular plant, soil and climate characteristics in Oregon. In 59 0.4-ha plots, we found 99 biotic crust lichen species, one-third of which were observed only once. Biotic crust lichen communities rich in cyanolichens characterized Juniperus stands whereas warm grasslands were home to regionally uncommon species including Texosporium sancti-jacobi and Rhizocarpon diploschistidina. We discerned biotic crust communities in sandy Artemisia tridentata ssp. wyomingensis sites from those loamy A.arbuscula sites. Hotspots of biotic crust lichen species richness were geographically scattered, weakly negatively associated with abundance of shrubs of disturbed sites. Gutierrezia and Chrysothamnus. The sites with lowest biotic crust lichen richness were heavily grazed, burned plots with Gutierrezia in the grassy north; unstable steep talus slopes at the center of the study area; and sandy, grazed sites with Chrysothamnus in the southern portion of our region. Overall, regional patterns in biotic crust lichen communities were strongly associated with vegetation, soils, and climate. © 2011.

    Abstract: Epiphytic lichen communities have become a focus for ecologists concerned with forest health because lichens are particularly responsive to forest management and air quality. Furthermore, they can contribute substantially to the diversity and nitrogen fixation of a stand, and play a valuable role in the food web of many forest-dwelling organisms. Can strategic thinning in Pseudotsuga -Tsuga forests increase biodiversity or hasten the development of late-successional features in young second-growth forests? Approximately 10 years after variable-density commercial thinning, N fixing and forage lichen species richness increased and lichen community composition was detectably diff erent from pre-thinning data and from unthinned controls. At two sites in moist conifer forests of western Oregon, lichen community monitoring plots were established before thinning treatments; the most diverse plots in each treatment were retained as diversity islands, whereas the less diverse plots were treated in the thinning prescription. At one site, we found that lichen communities in diversity plots were quite similar to those in the surrounding treated forest, and that the proportion of Tsuga heterophylla in the stand was negatively associated with alectorioid and cyanolichen richness. At both sites, hardwood gaps and open-grown trees were positively associated with N fi xing (cyanolichen) species richness. At the other site, surrounding plots were more like diversity "leave-islands" after thinning than before. Furthermore, thinned plots had more hardwood gaps following the thinning. Th ese thinned plots hosted more Bryoria, Candelaria concolor, Leptogium polycarpum, Peltigera collina, Nephroma laevigatum and Physcia tenella than had been observed prior to thinning. Most of those species are hardwood associates. Th e forage lichen Bryoria, however, is associated with older remnant trees in these stands. Forag e lichens may already be responding positively to the opened canopy in these stands, as evidenced by their association with plots having gaps in the canopy colonized by shrubs, and their increased abundance and frequency in 2007 in thinned plots at one of the two study sites. The retention of lichen hotspots appeared to allow rapid colonization of N fixers onto shrubs in thinned plots. Promotion of gaps in the conifer overstory that are dominated by hardwoods probably stimulated richness of N fixers and forage lichens by providing favorable substrates. We conclude that thinning treatments retaining remnants from previous cuttings, open-grown trees, and hardwood gaps have potential to favor lichen communities rich in cyanolichen and alectorioid species.

    Abstract: Biological soil crusts are ecosystem engineers in arid and semi-arid habitats; they affect soil chemistry, stability, and vegetation. Their ecosystem functions may vary depending on species composition; however, lichen species diversity is poorly known in the Pacific Northwestern drylands of North America. We sampled 59 random and 20 intuitive plots throughout central and eastern Oregon identifying 99 lichen taxa, 33 of which occurred in only one plot and seven of which were new to Oregon (Acarospora obpallens, A. terricola, Catapyrenium psoromoides, Placidium fingens, P. pilosellum, P. yoshimurae and Psora luridella). We compile records from herbaria and other studies to evaluate the rarity of observed species and potentially rare species known from nearby locations. We conclude that 37 species are likely rare or uncommon in our study area. Many of these appear to be associated with calcareous substrates. We model occurrences in relation to climate and soil variables for four uncommon lichen species: Acarospora schleicheri, Fuscopannaria cyanolepra, Rhizocarpon diploschistidina, and Texosporium sancti-jacobi. Based on climate and soil variables, we map regions of Oregon that may support new populations of these species and overlay habitats unsuitable for biotic crusts due to development and agriculture. These species, except Fuscopannaria cyanolepra, are strongly associated with the fine soils along the Columbia and Treasure Valleys that are most intensively used for agriculture. We anticipate that our summaries will further the understanding of lichen component of biological soil crust communities in eastern Oregon and suggest focal species for future conservation efforts. © 2011 The American Bryological and Lichenological Society, Inc.

    Keywords: biotic soil crust/ lichens/ bryophytes/ surveys/ calcareous soils/ sagebrush/ Texosporium
    Abstract: Arid lands of eastern Oregon and Washington support a great diversity of biotic soil crust organisms that are often overlooked in biotic inventories. Land managers are increasingly interested in incorporating these species in their surveys so that they can protect unique habitats and prevent uncommon species from becoming threatened. Current monitoring guidelines for rangeland health sometimes take into account the percent cover by soil crusts; however, there is very little guidance for surveying for uncommon species. Furthermore, because soil crust species and habitats are unfamiliar to most botanists, finding these species presents special challenges. We outline suggestions for future surveys with these goals

    Keywords: Alaska/ community analysis/ climate/ epiphytes/ thresholds
    Abstract: Because of their unique physiology, lichen communities are highly sensitive to climatic conditions, making them ideal bioindicators for climate change. Southeast and south-central Alaska host diverse and abundant lichen communities and are faced with a more rapidly changing climate than many more southerly latitudes. We develop sensitive lichen-based indicators for tracking the effects of climate change in south-central and southeast Alaska. Using 196 plots, we model community composition and 12 individual species abundances in relation to synthetic climate variables. Both types of lichen indicator are closely related to the climate variable describing a transition from warm, wet oceanic climates to cooler, drier suboceanic climates. Lichen communities and individual species exhibited thresholds associated with average December minimum temperatures between −10.2 and −7.8°C and annual precipitation between 106 and 172 cm, suggesting rapid turnover with relatively small changes within these ranges. These climate conditions occur close to the coast in northern portions of the region and further inland in southeast Alaska. Because lichen communities in the threshold region may be most sensitive to a changing future climate, they should be targeted for monitoring efforts.

    Abstract: Introduction Biotic soil crust communities contribute valuable ecosystem services and biodiversity in steppe ecosystems. The uncommon crust lichens Acarospora schleicheri, Fuscopannaria cyanolepra, Rhizocarpon diploschistidina, and Texosporium sancti-jacobi are associated with fine-textured soils along rivers of the Columbia Basin. A. schleicheri and R. diploschistidina indicate late-successional habitat and may serve as indicators for other rare or cryptic species associated with similar habitats. Much of the most favorable habitat for these species has been lost to urban and agricultural development. We sought to overlay favorable habitats with wind farm development potential to assess whether these species are likely to be affected by renewable energy development. Methods We overlaid habitat models for four lichen species on land use and wind farm potential maps. Using a sample of 5,000 points, we determined whether there were differences in probability of occurrence among wind farm potential classes within developed and natural lands using Multi-Response Permutation Procedures. Sites with modeled probability of occurrence greater than 60% were considered “favorable” habitats; for these, a χ2 test allowed us to determine whether favorable habitats were associated with wind farm potential categories. Results Sites that are developed for agriculture or have higher wind farm potential coincide with more favorable habitats for uncommon soil crust lichens. Of the favorable habitats for the four focal lichens, 28–42% are already affected by development or agriculture; 5–14% of favorable habitats remain in natural vegetation and are considered sites with fair or good potential for wind farms. Conclusions Development of wind energy has the potential to negatively impact uncommon soil crust lichen species because favorable sites coincide with especially good habitat for these species. However, as these renewable energy resources are developed, we have the opportunity to ensure that valuable soil crust functions and diversity are maintained by surveying before construction and planning new facilities such that disturbance to existing habitat is minimized.

    Abstract: Isolated populations of four reindeer lichen species and varieties co-occur in a unique relict prairie habitat at Mima Mounds Natural Area Preserve, southwest Washington State, USA. The prairie is the type locality for mima mounds, unusual geologic features providing topographical variation that influences vegetation patterns. Reindeer lichens (Cladonia subgenus Cladina) are usually more typical of northern boreal regions and are very rare in inland valley habitats of the western states outside of Alaska. Our study established distributional, ecological, chemotypic, and phylogenetic information for the target species. The species that at first appeared to be C. arbuscula was revealed by DNA sequences to be C. ciliata var. tenuis. We found that topography was not as important as recent fire history in explaining reindeer lichen distribution; in the future, prescribed fire is likely to benefit reindeer lichens so long as it preserves pockets of refugia as propagule sources. We also detected moderate air pollution stress, which is projected to have impacts on lichen abundances and community compositions in the near future. Chemotype analysis revealed 6 reindeer lichen chemotypes, of which 2 are rare (C. ciliata var. tenuis and C. portentosa subsp. pacifica f. decolorans). Phylogenetic analyses supported previous species concepts, showing C. portentosa is distinct from the closely-related group that includes C. rangiferina and two varieties of C. ciliata. We synthesized our findings to provide a key for distinguishing the reindeer lichens of Mima Prairie. We suggested that rare inland reindeer lichens may benefit from small prescribed burns and sowing of propagules in disturbed areas, as well as continued monitoring and designation as state sensitive species. © 2012 Pacific Northwest Fungi Project All rights reserved.

    Keywords: Biomass/ boreal forests/ bryophyte and lichen ecology/ carbon sequestration and cycling/ climate change/ ecosystem functions/ Forest Inventory and Analysis program/ land-use change/ soil nutrient cycles
    Abstract: Mat-forming “ground layers” of mosses and lichens often have functional impacts disproportionate to their biomass, and are responsible for sequestering one-third of the world's terrestrial carbon as they regulate water tables, cool soils and inhibit microbial decomposition. Without reliable assessment tools, the potential effects of climate and land use changes on these functions remain unclear; therefore, we implemented a novel “Ground Layer Indicator” method as part of the U.S.D.A. Forest Inventory and Analysis (FIA) program. Non-destructive depth and cover measurements were used to estimate biomass, carbon and nitrogen content for nine moss and lichen functional groups among eight contrasted habitat types in Pacific Northwest and subarctic U.S.A. (N  =  81 sites). Ground layer cover, volume, standing biomass, carbon content and functional group richness were greater in boreal forest and tundra habitats of Alaska compared to Oregon forest and steppe. Biomass of up to 22769 ± 2707 kg ha−1 (mean ± SE) in upland Picea mariana forests was nearly double other reports, likely because our method included viable, non-photosynthetic tissues. Functional group richness, which did not directly correspond with biomass, was greatest in lowland Picea mariana forests (7.1 ± 0.4 functional groups per site). Bootstrap resampling revealed that thirty-two microplots per site were adequate for meeting data quality objectives. Here we present a non-destructive, repeatable and efficient method (sampling time: ca. 60 min per site) for gauging ground layer functions and evaluating responses to ecosystem changes. High biomass and functional distinctiveness in Alaskan ground layers highlight the need for increased attention to currently under-sampled boreal and arctic regions, which are projected to be among the most active responders to climate change.

    Abstract: Delimiting species boundaries among closely related lineages often requires a range of independent data sets and analytical approaches. Similar to other organismal groups, robust species circumscriptions in fungi are increasingly investigated within an empirical framework. Here we attempt to delimit species boundaries in a closely related clade of lichen-forming fungi endemic to Asia, the Hypogymnia hypotrypa group (Parmeliaceae). In the current classification, the Hypogymnia hypotrypa group includes two species: H. hypotrypa and H. flavida, which are separated based on distinctive reproductive modes, the former producing soredia but absent in the latter. We reexamined the relationship between these two species using phenotypic characters and molecular sequence data (ITS, GPD, and MCM7 sequences) to address species boundaries in this group. In addition to morphological investigations, we used Bayesian clustering to identify potential genetic groups in the H. hypotrypa/H. flavida clade. We also used a variety of empirical, sequence-based species delimitation approaches, including: the “Automatic Barcode Gap Discovery” (ABGD), the Poisson tree process model (PTP), the General Mixed Yule Coalescent (GMYC), and the multispecies coalescent approach BPP. Different species delimitation scenarios were compared using Bayes factors delimitation analysis, in addition to comparisons of pairwise genetic distances, pairwise fixation indices (FST). The majority of the species delimitation analyses implemented in this study failed to support H. hypotrypa and H. flavida as distinct lineages, as did the Bayesian clustering analysis. However, strong support for the evolutionary independence of H. hypotrypa and H. flavida was inferred using BPP and further supported by Bayes factor delimitation. In spite of rigorous morphological comparisons and a wide range of sequence-based approaches to delimit species, species boundaries in the H. hypotrypa group remain uncertain. This study reveals the potential limitations of relying on distinct reproductive strategies as diagnostic taxonomic characters for Hypogymnia and also the challenges of using popular sequence-based species delimitation methods in groups with recent diversification histories.
