Remarks (public):The genus is not especially well defined. The repetition of basidia occurs only occasionally in G. incrustans and is thus of little value for the generic diagnosis. It seems, however, to be sufficiently well distinguished by the curved, allantoid spores and the constricted to urni-
form basidia with 4 sterigmata. The pleurobasidia occurring in G. pedicellata would place it among the primitive Basidiomycetes, in the meaning of Oberwinkler, but such basidia can be found in so many Corticiaceae and other Basidiomycetes, that they do not say much about the relations. We think that the arrangement made by Parmasto (Galzinia placed in subfam. Sistotrematoideae) is acceptable, as there are traits joining Sistotrema and Galzinia.
Two or three species in N. Europe. Besides Rogers (Mycologia 36:1 p. 99, 1944) described two species from N. America. One of these, G. cymosa Rogers, differs from the others in lacking clamps.
