[3] Threats to its habitat have resulted in the Lilac Pinkgill being assessed as globally "vulnerable" on the IUCN Red List of Threatened Species.

[1] The species was first described by Swedish mycologist Elias Magnus Fries in 1857 as Agaricus porphyrophaeus, the epithet derived from Ancient Greek πορφύρα ("purple") and φαιός ("dusky").

Entoloma fuscomarginatum and E, elodes are species of Sphagnum and peat bogs, the former with a brown edge to the lamellae.

[1] Like many other European pinkgills, it occurs in old, agriculturally unimproved, short-sward grassland (pastures and lawns).

Entoloma porphyrophaeum is typical of waxcap grasslands, a declining habitat due to changing agricultural practices.
