Collybia
Braunknolliger Sklerotienrübling ( Collybia tuberosa )
The dwarf or Sklerotienrüblinge ( Collybia s.str. , Syn. Microcollybia ) is a fungal genus of the family of Tricholoma relatives, which form very small fruiting bodies and often fruiting bodies from a lentil to a pea-sized sclerotia.
The type species of the genus is the Braunknollige Sklerotienrübling ( Collybia tuberosa ).
Features
The species of this genus have a white or light cream colored spore powder. The hat is whitish in color and has a membranous - thin consistency. The fins are whitish and quite high. They are crowded and have grown up bulged grown. The stem is cylindrical and is substantially longer than the hat width. The sclerotia from which the fruiting bodies are often grow yellow, purple, brown or black in color.
The hyaline spores are never dextrinoid. They are ellipsoidal in shape and have a thin wall and a smooth surface. The hat skin consists of simple hyphae, which are either free of pigment, or contain an intracellular pigment. They are parallel or intertwined. The lamellae is regular. The hyphal septa have buckles. The basidia are cylindrical - clavate shaped, have four sterigmata and a basal buckle.
Ecology
The fruiting bodies appear sociable. They often grow from sclerotia, which applies the fungus on or near mummified large mushrooms.
Species
The genus includes 3 species which occur in Europe all around the world. Earlier also the Traubenstielige Sklerotienrübling was to be counted, the only way today dressed as the genus Dendrocollybia.
