New and rare for Ukraine taxa of the genera Conocybe and Pholiotina (Bolbitiaceae, Basidiomycota)

Abstract

The data about finds of some new and rare for Ukraine taxa of the genera Conocybe and Pholiotina are reported. Four species (Conocybe intrusa, C. subalpina, Pholiotina intermedia, P. vexans) and two varieties (Conocybe albipes var. rugata та C. juniana var. juniana) are reported for Ukraine for the first time in, while for four species (Conocybe pilosella, C. pulchella, C. rostellata і C. subovalis) new localities are recorded. Data on distribution in Ukraine and in the world are presented for all reported representatives of both genera. For the taxa newly reported for Ukraine, descriptions and original drawings of the collected specimens are provided. Since all new for Ukraine species and varieties (excluding C. subalpina) were earlier reported by the author (Prydiuk, 2015) as potentially present in our country, their descriptions given in the article have been corrected according to new data. Particular attention is paid to C. albipes var. rugata and C. intrusa. The fruit bodies of the first taxon probably contain phallotoxins which were found in the fruit bodies of C. albipes var. albipes; therefore, it is a potentially dangerous poisonous fungus. The second fungus is an alien thermophilic species in Europe and Ukraine.
