Gloiocephala

Gloiocephala is a genus of fungi in the family Physalacriaceae. The genus is widespread, though mainly known from tropical and sub-tropical areas, and contains about 30 species. The mushrooms of this group are very small and grow on stems and leaves of monocotyledonous plants, such as sedges, usually in wet places. In most species their fruiting bodies do not develop into a typical mushroom form - the gills are often reduced to vein-like structures or completely missing, and the stipe may be asymmetrical, short or absent. There are five species which grow in Europe: G. caricis, G. cerkesii, G. cornelii, G. menieri and G. pseudocaricis....read more on Wikipedia.
