The kernel or fibrous lumps ( Psathyrella ) are a genus of fungi from the family of kernel relatives . The species are usually of no interest to mushroom pickers and difficult to determine, but some are very common.
features
Macroscopic features
The often hygrophane hat is bell-shaped at the beginning, the brim is never rolled up. The hat is always in the middle of the stem . This is easy to break off. The lamellae are usually free or grown and not piebald. The spore powder is dark, usually black or at least brown in color.
To differentiate between the individual species, the even livelier color in younger fruiting body specimens, possible hygrophanity and remnants of a possibly existing partial envelope are often particularly helpful.
Microscopic features
are often decisive for the differentiation of the outwardly quite similar Mürblingsarten. The spores have a smooth surface with a clear germ pore.
Generic delimitation
Crumbles usually differ from manure pieces ( Panaeolus ) in that their spores fade in concentrated sulfuric acid. In representatives of the genera Coprinellus and Coprinopsis , the hats of the fruiting bodies digest themselves. Another similar genus is Coprinus .
ecology
The Mürblinge all feed saprophytic .
history
The current group was established in 1838 by Elias Magnus Fries as a tribe of his all-encompassing genus Agaricus and in 1872 by Lucien Quélet raised to the rank of a genus. The name is derived as a diminutive of Psathyra from the Greek word psathuros (ψαθυρος), which means "roastable".
