Aerophytic green algae, epimycotic on Fomes fomentarius (L. ex Fr.) Kickx.

Abstract

Four species of green algae were found on the upper surface of Fomes fomentarius (L. ex Fr.) Kickx. basidiome. Desmococcus vulgaris (represented by both vegetative cells and aplanosporangia) dominated among them. Trebouxia arboricola (represented by free-living vegetative cells and autosporangia), and two species of Stichococcus (S. bacillaris, S.minutus) were the other identified algae. It is proposed to use the term “epimycotic” (from the greek “epi”- over and “mykes” – fungus) for algae and/or other organisms capable of growing and developing on the upper surface of fungal fruiting bodies.
