Entoloma sericatum can be recognized by a fleeting nitrous odor that quickly changes to farinaceous, a dark yellowish brown umbonate cap, and stuffed white stipe up to 20 mm thick. Entoloma lividoalbum differs primarily in lacking an initial nitrous odor and in having a thicker cap context and solid stipe. Entoloma nidorosum has a similar nitrous odor but differs in a centrally depressed, distinctly translucent- striate brownish orange cap, thinner cap context, a hollow stipe less than 10 mm broad, and growth with conifers.
