About Entoloma porphyrophaeum (Fr.) P.Karst.
Entoloma porphyrophaeum (Fr.) P.Karst. produces agaricoid basidiocarps that grow up to 175 mm (7 in) tall. The cap starts conical, becoming convex to flat and broadly umbonate as it matures, reaching up to 145 mm (5.5 in) across. The cap surface is smooth and finely fibrillose, colored lilac to purple-brown that fades or darkens to brown with age. The lamellae (gills) are white to cream when young, turning pink from mature spores. The stipe (stem) is smooth, finely fibrillose, the same color as the cap or paler, and lacks a ring. The spore print is pink. Under a microscope, spores are multi-angled, inamyloid, and measure around 8 to 12 by 6 to 8 μm. Cheilocystidia are either rostrate with a simple apical projection or capitate with a spherical apical projection. This species, known as the Lilac Pinkgill, is rare but widespread in Europe. Like many other European pinkgills, it occurs in old, agriculturally unimproved, short-sward grassland including pastures and lawns.
