Abstract: The spores of Bryum caespiticium Hedw., B. capillare Hedw., B. creberrimum Taylor, B. imbricatum (Schwägr.) Bruch &Schimp. and B. subelegans Kindb. were studied by light and scanning electron microscopy for the first time. The apertural regionconsists of a leptoma in all spores. Two spore types, characterized by their surface ornamentation, are established, refl ecting thespecies taxonomic relationships. While surface ornamentation is of a piloid type in Bryum imbricatum, it is of granuloid type inB. caespiticium, B. capillare, B. creberrimum and B. subelegans. The spore wall of the family Bryaceae includes sclerine (thedinstinction between exine and perine may be difficult to define) and intine. The taxonomy of the genera Bryum is discussed onthe basis of their spore morphology.
