The Arctic has been, and is, an area of focus for the botanical and fungal (lichenized fungi included) collections at the Natural History Museum of Oslo. These collections house more than 233,000 unique Arctic specimens, the oldest dating back more than two centuries. The vascular plants account for 63 percent, lichens 30 percent, and fungi 7 percent. The Arctic collections have a circumpolar representation with emphasis on mainland Norway (48 percent) and Svalbard (13 percent), followed by Arctic … Read more... 

Despite the growing interest in the lichen communities of Mexico, little is known about the assemblages from the central part of the country. For that reason, we defined the following research objectives: 1) to compare species richness, composition, and dissimilarity of lichen communities among three vegetation types; 2) to explore the incidence of environmental variables on lichen community species composition; and 3) to identify species and functional traits indicative of each vegetation … Read more... 

Cyphellostereum indicum, an interesting basidiolichen is described as a new species. The species was collected from Arunachal Pradesh, an Indian state located within the Eastern Himalayas. The species is characterized by a terricolous habitat, the cyanobacteria Rhizonema as the photobiont that is loosely wrapped by fungus hyphae, white to cream-coloured, flabellate, solitary hymenophores, and thin-walled, smooth, simple, irregular to pip-shaped basidiospores 3.18–4.9 × 2.06– 2.9 μm. … Read more... 

In order to provide data for lichenologists studying taxonomy, Chaenothecopsis xishuiensis is supported and proposed as a new species from China based on phenotypic, molecular, and metabolite data. It is characterised by leprose thallus, single, conical to hemispherical apothecia, nonbranching stipe, cylindrical, eight-spored asci, and nonseptate and brown spores, and this lichenised fungus contains atranorin and zeorin in the thallus. In addition, Lecanora pseudargentata is reported for the first … Read more... 

Four species of Porpidia are newly reported from China, including one species new to science (Porpidia crystallina) and three records (Porpidia umbonifera, P. seakensis and P. cf. contraponenda) new to China. Porpidia crystallina is characterized by a macrocarpa-type exciple containing crystals, a Cinereorufa-green epihymenium, large ascospores and a lack of secondary metabolites. Morpho-anatomical, chemical and phylogenetic analyses were carried out to elucidate the placement of the species and … Read more...
