The Coprinus disseminatus (Coprinus disseminatus) fungus is very common that almost always comes after heavy rains and lasts at most a few days. It is saprobic, growing in clusters, often by the hundreds; on decaying wood.
They are very thin and fragile and the caps quickly crumble when handled. 
Its cap is minute up to 2 cm wide and is on a smooth often curved white (1.5-4 cm long; 1-2 mm thick) hollow stalk.
They are saprobes, assisting in the decomposition of wood, forest litter, and so on. They grow growing in clusters and sometimes in astounding numbers. Found often by the hundreds on decaying wood especially near the bases of stumps. It appears spring, summer and autumn. Its cap is initially white but soon begins to turn greyish brown, with a brownish centre.
C. disseminatus does not dissolve into black ink (deliquesce) in maturity like other of this genus.  Coprinellus disseminatus is easily recognized as a coprinoid mushroom by its cap shape and greyish black gills. It is Inedible.

These little mushrooms last only a few days. See daily photos below
