Epibryon kondratyukii sp. nov., a new algicolous fungus, and notes on rare lichenicolous fungi collected in Southern Ukraine

Abstract

The new algicolous fungus Epibryon kondratyukii sp. nov. grows on Coccomyxa-like films on leaves of Polytrichum piliferum in Southern Ukraine. The species is characterized by sessile black setose pseudothecia, short 0–2-celled paraphysoids, 8-spored fissitunicate asci and hyaline 0–1-septate ascospores. The lichenicolous fungi Adelococcus interlatens, Ascochyta candelariellicola, Clypeococcum psoromatis, Epithamnolia rangiferinae, Lawalreea lecanorae, Llimoniella adnata, Merismatium decolorans, Sphaerellothecium cladoniae, Stigmidium bellemerei, S. ramalinae and Weddellomyces epicallopisma are new to the mycobiota of the Ukraine. Cladonia foliacea is a new host for Epithamnolia rangiferinae, Lecidea fuscoatra for Katherinomyces cetrariae, and Flavoplaca austrocitrina for Weddellomyces epicallopisma.
