SIMILAR SPECIES:

superficially similar to cultivated mushroom [1]

danger of confusing with inedible or weakly poisonous hebolomas and with very poisonous inocybe erubescens[2]

Inocybe erubescens has brown spore print (tobacco brown [2]) instead of white spore print. The smell is sweet instead of mealy, the taste is 'unpleasant' and like all other brown gilled fungi it shouldn't be eaten [2]. The gills start out white with a faint pink tinge which is probably the easiest point to misidentify them. Inocybe erubescens flesh is reddening [2]
