Hypholoma fasiculare

Hypholoma fasiculare can be recognized by the sulphur-yellow colors to the clustered, fruiting bodies, the purple-brown spores which are often found on the pileus surface, the cortinate veil in the button stage, the greenish gills when young, the very bitter taste, the substrate which is rotting wood. Hypholoma capnoides is similarly colored as H. fasiculare but differs from it by the grayish gills when young and the mild taste. Pholiota malicola is somewhat similarly colored as H. fasiculare but differs by its brown spores, terrestrial substrate from which the fruiting boides grow out of woody debris, and the stipe base which becomes brown.

Hypholoma fasiculare is toxic and causes severe diarrhea and emesis.
