Ascomycete species new to Lithuania

In this paper three ascomycete species, Capronia nigerrima, Kalmusia clivensis and Sillia ferruginea, are reported for the first time in Lithuania. The fungi were found on old stromata of pyrenomycetes, bark of dead branch of Corylus avellana and dead stems of Rubus idaeus in the alluvial forests with Alnus glutinosa of the southern, northeastern and eastern Lithuania. Morphological descriptions, comments and illustrations of the species are presented.
