New records of rare wood-inhabiting fungi from the Ukrainian Carpathians.

Abstract

The Ukrainian Carpathians provide an important refuge for rare lignicolous fungi due to one of the largest areas of old-growth forests in Europe. During 2019–2022, new localities of 13 noteworthy species of lignicolous fungi were revealed on the northeastern macroslope of the Ukrainian Carpathians (Gorgany Nature Reserve, vicinities of the towns of Nadvirna and Yavoriv). Of these, Sistotrema alboluteum is a new species for Ukraine. In addition, we report two rare species restricted to natural forests, Amylocystis lapponica and Crustoderma dryinum , which had not been recorded in the country for over 80 years. Locality data and habitat types for all reported species as well as detailed descriptions and illustrations of the most interesting finds are provided. Ecology and distribution of some species are briefly summarised.
