Roseodiscus (Hymenoscyphus) subcarneus
Parasitic on Mosses and Liverworts
The tiny frutibodies are less than a millimetre across and consist of thin, translucent, whitish discs (apothecia) on short whitish stalks. This species attacks moss gametophytes and has also been reported to attack liverworts. The parasitized moss dies, turns brown, and the fungus then produces scattered stalked discs over the surface of the dead moss. The healthy green moss can be seen on either side of the infected moss.
