What You Should Know
Entoloma prunuloides belongs to a species complex (Morgado et al. 2013) of at least three closely related species (E. prunuloides s. str., E. pseudoprunuloides, and E. ochreoprunuloides). According to present knowledge, there are no extra-European records of E. prunuloides that are confirmed by DNA sequence analyses. Therefore, all records of this species outside of Europe should be treated as doubtful until confirmed by molecular and morphological methods.
It has a white to ochre-brown cap with a mealy odor and taste. It is widespread in Europe and grows in mountain meadows, less often in lowlands.
Other names: Mealy Pinkgill, Molenaarssatijnzwam (Netherlands), Závojenka mechovkovitá (Czech Republic), Melrødspore (Norway), Mehl-Rötling (Austria), Kalvasrusokas (Finland).

Entoloma prunuloides Taxonomy and Etymology
In 1821 Elias Magnus Fries described this species in his Systema Mycologicum he gave it the scientific (binomial) name Agaricus prunuloides.
In 1872 the French Mycologist Lucien Quélet transferred this species to its present genus, whereupon its scientific name became Entoloma prunuloides.
The generic name Entoloma comes from ancient Greek words entos, meaning inner, and lóma, meaning a fringe or a hem. It is a reference to the inrolled margins of many of the mushrooms in this genus.
The specific epithet prunuloides means 'similar to prunulus', which in turn is nothing to do with prunes but simply means pruinose - frosted as if covered in a fine white powder.
