Abstract: Para o Estado do Rio Grande do Sul são conhecidas aproximadamente 1000 espécies de fungos liquenizados, sendo que apenas 15 destas pertencem ao gênero Ramalina Ach. No presente trabalho são apresentadas cinco novas ocorrências, uma espécie é excluída e cinco espécies não são confirmadas para o Estado. Foi realizada uma revisão dos espécimes de Ramalina depositados em ICN (Universidade Federal do Rio Grande do Sul). As análises morfológicas foram realizadas sob microscópios estereoscópico e óptico; cortes anatômicos foram feitos à mão livre. Análises químicas seguiram metodologia padrão em liquenologia. Foram analisados 306 exemplares sendo registradas cinco novas ocorrências: Ramalina anceps Nyl., R. camptospora Nyl., R. cochlearis Zahlbr., R. dendriscoides Nyl. e R. pusiola Müll. Arg. A espécie Ramalina subfraxinea Nyl. foi excluída da micota do estado uma vez que todos os exemplares identificados com esse nome eram na realidade R. celastri (Spreng.) Krog & Swinscow. Ambas podem ser diferenciadas pelo formato das pseudocifelas (puntiformes em R. subfraxinea; lineares em R. celastri) e pela produção de compostos secundários medulares (ácidos homosequicaico, sequicaico e ramalinólico em R. subfraxinea; ausência de compostos medulares em R. celastri). Ramalina puiggarii Müll. Arg. foi citada para o município de São Francisco de Paula, porém, não foram depositados exemplares no herbário ICN. Em recente coleta realizada em uma localidade do mesmo município, R. puiggarii não foi encontrada, mas espécimes de R. camptospora eram muito frequentes. Ambas as espécies são similares morfologicamente, porém diferem principalmente no tamanho dos ascósporos (maiores em R. puiggarii), colocando em dúvida a ocorrência da mesma para o Estado. Quatro outras espécies ainda necessitam de confirmação: Ramalina eckloni var. sublinearis (Nyl.) Malme, R. laevigata Fr. e R. linearis (Sw.) Ach., que provavelmente sejam identificações incorretas de R. celastri, e R. yemensis (Ach.) Nyl., que possivelmente é R. usnea (L.) R. Howe.

Abstract: The new species Ramalina fleigiae from Brazil is described growing on rocks in riverbeds in high altitude grasslands of southern Brazil. It grows in areas with constant water flow, sometimes almost immersed, and always in exposed habitats. Through an integrative approach, the detailed description of R. fleigiae includes morphological, anatomical, ecological, chemical and molecular data. Ribosomal DNA-based phylogenies suggest that R. fleigiae is more closely related to a species that shares its habitat preference (R. laevigata) than to the morphologically and chemically similar R. exiguella and R. gracilis. Ramalina fleigiae and R. laevigata can be distinguished by thallus morphology (irregularly flat branches in R. fleigiae vs. flat to canaliculate in R. laevigata) and pattern of chondroid tissue, as genetic distances between them are compatible with the interspecific range. It is possible that many species of Ramalina still remain hidden within the morphological or chemical variation of currently accepted species. Combining ecological, anatomical and molecular data will improve our future understanding of this genus.

Abstract: In the tropics, corticolous lichen richness and cover tend to increase from the trunk base to the top of the crown of trees. In this study we calculated the total beta diversity of the lichen community along a vertical gradient on Quercus laurina in Mexican cloud forest. By comparing the richness and cover of the lichens by zone, we show that foliose and fruticose lichens are a minor component of the total lichen species richness, but have a higher cover than the crustose lichens. Five zones were identified along each phorophyte (n = 15) with a diameter at breast height >40 cm. A total of 92 species were identified. Of these, 38% were found only in a single zone, 51% were shared between the different zones and 11% occurred across all zones. Species richness and cover increased from the lowest to the highest zones of the phorophytes. Dissimilarity in species composition between the zones could be explained by species replacement. An indicator species analysis revealed that only a few species, e.g. Hypotrachyna vexans, H. cf. sublaevigata and Ramalina cf. sinaloensis prefer a particular zone. The results show that the lichen community associated with Quercus laurina phorophytes is highly diverse and suggest that species richness and cover are related to the zone and the various growth forms.

Abstract: The two frequent Ramalina species in southern South America are R. laevigata Fr., which has abundant apothecia, and R. terebrata Hook. f. & Taylor, which lacks apothecia but has abundant sorediate pseudocyphellae. However, two other taxa that predate Hooker and Taylor’s name were described from the Falkland Islands. These names are investigated here and R. flaccidissima Bory is shown to be the correct name for R. terebrata.
