New and little known in Ukraine representatives of the genus Cortinarius (Cortinariaceae, Basidiomycota) from Male Polissia National Nature Park

Abstract

Data on some noteworthy finds of interesting representatives of the subgenus Telamonia of the genus Cortinarius in Ukraine are presented. Two of them, C. decipiens var. atrocoeruleus and C. flexipes var. flabellus, have been registered for the first time in Ukraine; the typical variety of the former species is still unknown in our country. Other two taxa are rarely reported in Ukraine; those are C. flexipes var. flexipes, known also from Left-Bank Polyssia, and C. diasemospermus, so far recorded only in the Ukrainian Carpathians. All taxa were found in Male Polissia National Nature Park (Khmelnytsky Region), C. diasemospermus was also collected in Shatsky National Nature Park. The data about their distribution in Ukraine and worldwide, detailed descriptions of macro- and microscopical features, as well as original photos of the fruit bodies and drawings of the spores are provided. It should be noted that all these taxa are quite common in appropriate habitats in Europe and usually are not considered rare. Probably in Ukraine they also occur more often than they are reported at present and new finds of these species and varieties can be expected.
