This mushroom is characterized by yellow, orange-yellow, or greenish-yellow caps. The surface of the cap is bald, not sticky or slimy. Gills are yellow to greenish-yellow when young, becoming gray to purple-black with age. Stalk is slender, yellow or tawny. Spores are deeply colored (purple-brown to deep purple-gray). Growing in tufts or clusters on rotten wood (logs, stumps, and wood chips; widespread and common on hardwoods as well as conifers). Small to medium-sized (2-7 cm broad, 2-9 cm tall) ; cap domed when young, becoming flatter in age; transient veil present when young, sometimes leaving remnants on the edge of the cap or a very slight ring on the stalk; volva absent; taste is usually bitter.
Although only very rarely fatal, poisoning by Hypholoma fasciculare is occasionally reported and it can result in severe symptoms, including stomach pains, nausea and also temporary paralysis and distorted vision. There is a delay of typically five to ten hours between ingestion of these fungi and the appearance of symptoms of poisoning.
