A number of gilled mushrooms are similar-looking, including those where the cap becomes upturned in age, exposing the gills. Such mushrooms differ by having "true" (i.e., blade-like) gills rather than forking, vein-like ridges. The poisonous
Omphalotus olivascens differs in that it has true gills and grows in clusters where the stems are fused. The poisonous
Paxillus involutus differs in that it has a brownish cap, true gills, and a brown spore deposit.
