The new Tremella umbilicariae, lichenicolous on Umbilicaria, is described from Peru. It is characterized by large, dark brown, convex basidiomatal galls, long and narrow basidia, and relatively large basidiospores.

Forty-four new lichen species and one lichenicolous fungus have been identified as a result of studies the biota Franz Josef Land archipelago. Bryocaulon hyperboreum was reported for first time from Russia. Gyalecta hypoleuca Umbilicaria maculata were in Arctic. Arctocetraria andrejevii, Brodoa oroarctica, Candelariella borealis, Cercidospora stereocaulorum, Massalongia carnosa, Miriquidica nig...

Seven species new to science are described, illustrated and compared with closely related taxa. Of them, one species, i.e.: Coppinsidea vernadskiensis S. Y. Kondr., T. O. Kondratiuk et I. Yu. Parnikoza is from the Argentine Islands, Western Maritime Antarctic Peninsula, Jacke lixia hosseussii L. Lőkös J.-S. Hur, South America (Argentina Uruguay), Loekoeslaszloa reducta Yoshik. Yamam.

Though most of the lichenicolous fungi belong to the Ascomycetes, their phylogenetic placement based on molecular data is lacking for numerous species. In this study the phylogenetic placement of 19 species of lichenicolous fungi was determined using four loci (LSU rDNA, SSU rDNA, ITS rDNA and mtSSU). The phylogenetic analyses revealed that the studied lichenicolous fungi are widespread across ...
