The article provides information on distribution of some noteworthy representatives of the genus Galerina in Ukraine. This genus is still rather fragmentarily studied in the country, therefore it is a subject of a series of special articles. The previous two articles, on the species of Galerina with tibiiform cheilocystidia and those possessing pleurocystidia, have already been published. This article reports species with so-called calyptrate spores. In these spores, the outer layer of the spore wall (perisporium) is separated from the main wall to form blisters at the basal (sometimes also apical) part of the spore. One of the reported species, Galerina sahleri, was found for the first time in Ukraine; other three species (G. cerina, G. hypnorum, and G. sphagnicola) were recorded in new localities. All these fungi are bryotrophic, often sphagnicolous. Their diagnoses, data about finds in Ukraine and general distribution as well as original drawings of the fruit bodies and microstructures are provided.

Keywords: agaricoid fungi, distribution, Galerina sahleri, mosses, new records, perisporium, Ukraine
