Abstrakt

Gymnostomum viridulum Brid. was recorded from the Czech Republic on the basis of the Bauer’s exsiccata from Kralupy n. Vlt. (central Bohemia), studied by Whitehouse and Crundwell in herbaria BM, E, GL and NMW. The author of the present paper failed to find the diacritical character (axillary or rhizoidal gemmae) in specimens of the same exsiccatum deposited in herbaria PR and PRC. The gemmae were not present even in other specimens collected at the same locality, and the identification of these species as G. viridulum is therefore regarded to be doubtful. Typical plants of the species with axillary gemmae were nevertheless found in material of Z. Hradilek from a single locality near Alexovice (S Moravia), so the occurence of G. viridulum in the Czech Republic has been confirmed. A brief history of the taxon and its short description are given.
