Based on recent, very rich collections of Cytidiella albomellea (Bondartsev) Parmasto (= C. melzeri Pouzar) from South Bohemia (Czech Republic) the author lists all presently known localities and collections of this species in Bohemia and Slovakia. C. albomellea is only known from the Northern hemisphere, namely Europe, Asia and North America. Hosts are conifers (predominantly pines) as well as frondose trees and shrubs (mostly oaks). A taxonomic note on the genus Cytidiella is included.
