Abstract: ["We infer that remnant trees serve as refugia for lichens through a disturbance and provide lichen inoculum to younger trees. Hardwood patches were hotspots for lichen diversity, particularly cyanolichens that are infrequent on conifers. Hardwood patches were most prevalent along perennial streams. To maintain and enhance lichen communities at a landscape level, forest managers must consider the importance of features such as late-successional stands, remnant trees, hardwoods, and riparian areas to lichen communities. These features are especially important to retain in or near regenerating forests to promote colonization by dispersal-limited lichens." Only available online at http://pnwfungi.org/articles.htm

Abstract: We studied the evolutionary history of the Parmeliaceae (Lecanoromycetes, Ascomycota), one of the largest families of lichen-forming fungi with complex and variable morphologies, also including several lichenicolous fungi. We assembled a six-locus data set including nuclear, mitochondrial and low-copy protein-coding genes from 293 operational taxonomic units (OTUs). The lichenicolous lifestyle originated independently three times in lichenized ancestors within Parmeliaceae, and a new generic name is introduced for one of these fungi. In all cases, the independent origins occurred c. 24 million yr ago. Further, we show that the Paleocene, Eocene and Oligocene were key periods when diversification of major lineages within Parmeliaceae occurred, with subsequent radiations occurring primarily during the Oligocene and Miocene. Our phylogenetic hypothesis supports the independent origin of lichenicolous fungi associated with climatic shifts at the Oligocene–Miocene boundary. Moreover, diversification bursts at different times may be crucial factors driving the diversification of Parmeliaceae. Additionally, our study provides novel insight into evolutionary relationships in this large and diverse family of lichen-forming ascomycetes.

We report a total of 562 species of lichenized fungi from the Park, adding 461 species to the total of 101 species reported for the Park by the National Park Service database. An additional 22 lichenicolous fungi are reported here. Two nonlichenized fungi associated with young living twigs of particular host species are also included. An additional 75 species that are known from nearby areas in the Sierra Nevada, but not yet from Yosemite, are listed. Fourteen species are apparently newly reported for the Sierra Nevada, with an additional 17 species new to California, and five species new to North America (Gyalidea fritzei, Pyrenopsis reducta, Lecanora pseudosarcopidoides, L. sarcopidoides, L. subravida). Two taxonomic changes are included here: Verrucaria carbonusta Breuss is newly described, and Lecidea fuscoatrina Hertel & Leuckert is synonymized under the earlier but neglected name, L. cascadensis H.

Keywords: lichen growth/ Lobaria pulmonaria/ molybdenum/ nitrogen/ nitrogen fixation/ Pacific Northwest/ transplant experiment/ vanadium
Abstract: Nitrogen-fixing lichens (cyanolichens) are an important source of nitrogen (N) in Pacific Northwest forests, but limitation of lichen growth by elements essential for N fixation is poorly understood. To investigate how nutrient limitation may affect cyanolichen growth rates, we fertilized a tripartite cyanobacterial lichen (Lobaria pulmonaria) and a green algal non-nitrogen fixing lichen (Usnea longissima) with the micronutrients molybdenum (Mo) and vanadium (V), both known cofactors for enzymes involved in N fixation, and the macronutrient phosphorus (P). We then grew treated lichens in the field for one year in western Oregon, USA. Lichen growth was very rapid for both species and did not differ across treatments, despite a previous demonstration of P-limitation in L. pulmonaria at a nearby location. To reconcile these disparate findings, we analyzed P, Mo, and V concentrations, natural abundance δ15N isotopes, %N and change in thallus N in Lobaria pulmonaria from both growth experiments. Nitrogen levels in deposition and in lichens could not explain the large difference in growth or P limitation observed between the two studies. Instead, we provide evidence that local differences in P availability may have caused site-specific responses of Lobaria to P fertilization. In the previous experiment, Lobaria had low background levels of P, and treatment with P more than doubled growth. In contrast, Lobaria from the current experiment had much higher background P concentrations, similar to P-treated lichens in the previous experiment, consistent with the idea that ambient variation in P availability influences the degree of P limitation in cyanolichens. We conclude that insufficient P, Mo, and V did not limit the growth of either cyanolichens or chlorolichens at the site of the current experiment. Our findings point to the need to understand landscape-scale variation in P availability to cyanolichens, and its effect on spatial patterns of cyanolichen nutrient limitation and N fixation.

Abstract: Hypogymnia irregularis is newly described from southwest China, Nepal, Japan, and Taiwan. Similar in growth form to H. vittata, H. irregularis differs in always lacking soredia and having staggered, lateral, or almost randomly located perforations in the lower surface. In contrast, H. vittata usually produces soredia and has perforations more centered in the lower surface and axils. Hypogymnia vittata is known from Asia, North America, Central America, and Europe, while H. irregularis is endemic to Asia. Hypogymnia irregularis is postulated as being the fertile species that is the closest living relative to the sorediate H. vittata. Another Asian species, H. stricta, can be similar in appearance to H. irregularis and H. vittata, but can be differentiated both morphologically and chemically from those two.

Abstract: The type of Hypogymnia delavayi, together with the two associated specimens collected by Delavay, fit perfectly the distinctive species currently known as H. yunnanensis. Accordingly, H. yunnanensis is placed in synonymy with the older name H. delavayi; this species is now known only from southwest China. Many specimens representing the common subalpine to alpine ground-dwelling species in northern India and Nepal, previously placed in H. delavayi, are referred to H. alpina Awasthi. Reports of H. delavayi from Far East Russia belong to other species.

Abstract: I critically examine three powerful tool sets in lichen ecology that have fostered substantial contributions and are likely to receive heavy or increasing use in the coming years. These tool sets include species distribution (or habitat) modeling, field transplant experiments, and analysis of ecological traits. For each of these tool sets I discuss the ecological questions that they address, some example contributions, and critical issues with their application. Species distribution modeling is an important tool set for addressing climate change effects on lichens, but the methods can be mathematically opaque, conceptually naive, divorced from the species biology, and give results with inadequate characterization of prediction error and response surfaces. Field-based transplant experiments have been extremely productive in lichen ecology, but we have barely begun to appreciate the temporal stability or instability of the results, as revealed by multi-year studies showing large fluctuations in growth rates from year to year. Analysis of ecological traits of lichens is an increasingly popular effort to link performance of different kinds of lichens under various environments and disturbance regimes in a way that transcends particular species on particular continents. While methods for analyzing ecological trait data have proliferated, including advances that allow non-linear responses to environment, definition and widespread measurement of non-trivial quantitative traits for a large number of species has been virtually stalled at the starting line.

Abstract: Five new species are described from the group of Hypogymnia with rimmed holes on the lower surface: H. bulbosa, H. congesta, H. diffractaica, H. laxa, and H. pseudocyphellata. All species in this group are restricted to the Himalayan region, primarily in southwestern China. Four other species in this group have previously been described: H. hengduanensis, H. kangdingensis, H. macrospora, and H. subvittata. Hypogymnia kangdingensis is synonymized with H. hengduanensis and Hypogymnia subvittata is synonymized with H. macrospora. Virensic acid (in H. congesta) and norbarbatic (4'-O-demethylbarbatic acid) are major lichen substances previously unreported from Hypogymnia.

Abstract: Rhizocarpon quinonum McCune, Timdal & Bendiksby is described as a new species from two sites in Katmai National Park, south-western Alaska, in a suboceanic climate near the limit of trees on the Alaska Peninsula. Most similar in external appearance to R. arctogenum, R. bolanderi, R. leptolepis, and R. rittokense, the species is distinguished by the presence of an anthraquinone as a major substance. Mature apothecia are unknown, but ITS sequences are most similar to those of R. copelandii and R. jemtlandicum, although those species differ greatly in morphology from R. quinonum.

Abstract: Hypogymnia imshaugii is one of the most common, conspicuous and morphologically variable epiphytic lichens of the Pacific coastal states and provinces. The species varies greatly in morphology and chemistry, suggesting multiple closely related species or one or more phenotypically plastic species. We sought to determine whether additional ecologically meaningful species might be present within the H. imshaugii complex. Improving our species concepts could potentially improve ecological inferences based on community sampling. Three relatively well-defined genetic groups and one residual group in the H. imshaugii complex were detected with haplotype networks based on the ITS locus; however, phylogenetic reconstructions on combined ITS, mtSSU, GPD1 and TEF1 loci did not reflect this pattern. At present, we have insufficient evidence to support defining any of these groups as new taxa. The four major chemotypes in H. imshaugii differed in frequency among the genetic groups. None of the genetic groups was, however, qualitatively uniform in chemotype. Only one chemotype occurred in a single genetic group, but several chemotypes occurred in that group. While broadly sympatric, each chemotype had a distinct geographic distribution, and each chemotype showed its own relationship to climate, as shown by regression of occurrences of chemotypes against climatic variables. The genetic variation detected within H. imshaugii did not correspond to geographic variation in morphology, chemistry, or climate. Within the broader H. imshaugii complex, we recommend treating H. amplexa as a synonym of H. imshaugii unless it can be more distinctly separated from the clinal variation in morphology, chemistry, or DNA sequences. In contrast to H. amplexa, however, H. inactiva and H. gracilis are both easily separated morphologically from H. imshaugii and do not intergrade with it.

Abstract: We describe Umbilicaria nodulospora, a distinctive new species occurring on steep rock faces on old lava flows in California and Oregon. The species is unusual among lichenized ascomycetes in consistently having one or two shallowly bulging knobs at one end of each ascospore, suggesting a T, Y, or L shape; otherwise they are consistent with the appearance of ascospores in most Umbilicaria species. The species is readily distinguished in the field by a grayish tone to the brown upper surface, in combination with a thickly rhizinate lower surface. Distinctiveness of the species was supported by analysis of the ITS and LSU regions of nrDNA. No close relative or sister taxon was found. Umbilicaria nodulospora is so far known only from geologically recent flood basalts in central Oregon to northeastern California. © 2014 The American Bryological and Lichenological Society, Inc.

Abstract: Umbilicaria semitensis was described by Tuckerman in 1872 based on a specimen from Yosemite National Park. Despite the species having muriform spores, in contrast to simple spores in U. angulata, U. semitensis has long been treated as a synonym of U. angulata, owing to the superficial similarities of the thallus. Analysis of the ITS and LSU regions of nrDNA supports the hypothesis that the species are distinct. In addition to the spore and DNA differences, the two species are largely allopatric, and only know to co-occur in one site in Oregon. Umbilicaria semitensis ranges from southern California to southern Oregon, while U. angulata ranges from California to arctic Alaska.
