Sulphur Tuft

Hypholoma fasciculare


This saprophagic mushroom grows in tight clusters on decaying wood. The cap is smooth and bicolored: yellowish close to edges, and darker orange-brown in the center. There is also a black edge to the cap (well seen in Pic N° 1, which may be absent. The gills are crowded and initially yellow. With the time and maturity, they would darken to a green-blackish colour. The spore print (which I did not do) is brown. No particular smell.


Grows in clusters on dead and decaying wood on forest floor. Here, observed in an oak forest near Geneva, in Geneva lake valley, where it occurs abundantly and grows throughout the year.


Toxic. Could be confounded (at least in my eyes) with Galerina marginata (also toxic) and Kuehneromyces mutabilis (edible and appreciated)_
