The genus Coenogonium, the only genus in the family Coenogoniaceae, is mostly found in tropical and subtropical regions. Approximately 100 species of Coenogonium are known worldwide, and about 52 species have been previously recorded from Brazil. Here, we describe four species as new to science from the Atlantic Forest in the states of Bahia, Minas Gerais, and Sergipe, and present a few new state records. The new species are C. carassense, C. itabaianense, C. pilosum, and C. subtomentosum. An … Read more... 

A set of 44 taxa of lichenized fungi and 5 species of lichenicolous fungi was gathered in 1984 in the summit area of the mountain Glittertinden, the second highest mountain in Scandinavia. The sampled species include several high alpine taxa known as members of well-established alpine lichen communities but only few pioneer species indicating that the investigated rocks had already been ice-free for a long time. The local flora is compared to that reported from Scandinavia’s highest mountain, … Read more... 

National parks and other federally designated natural areas play critical roles in preserving unique habitats, communities, and biodiversity. However, in the United States, it is estimated that 80–90% of species diversity in national parks is presently unknown. Therefore, contemporary biodiversity inventories are critical for conservation, management and establishing baselines for future comparisons. Ongoing efforts to characterize lichen diversity highlight diverse and robust communities … Read more... 

The new combination Xenolecia masafuerensis is made for Lecanora masafuerensis, a lichen species known from only two localities on Isla Alejandro Selkirk in the Juan Fernández archipelago, Chile. The species is fully described and illustrated and shown to be morphologically and chemically distinct from the similar X. spadicomma, which is known only from Chile and the Falkland Islands. The typification of X. masafuerensis and its distribution on the islands are also discussed. Key words: distribution, … Read more... 

The new combination Thalloidima squamatum is proposed for a morphologically and phylogenetically distinct species, until now included within the variation of T. sedifolium. Compared to T. sedifolium, the species is characterized by its larger squamules and apothecia, shorter ascospores, the pale color of the excipulum, and its habitat growing on moss cushions over calcareous rock or directly on rock rather than on soil. Most of the material studied originates from Norway and Sweden, but specimens … Read more...
