Calocybe carnea

Pileus
Cap 1.5-3.0 cm broad, convex, becoming plano-convex, the disc occasionally depressed in age; margin when young, incurved, then decurved to plane, frequently wavy; surface when fresh, pinkish to vinaceous-brown, a whitish bloom sometimes evident near the margin, the cap typically glabrous at maturity, often fading to a watery tan-brown; context thin, firm, translucent pinkish-tan, unchanging; odor not distinctive; taste somewhat pungent, disagreeable.

Lamellae
Gills adnate, crowded, narrow, pallid, cream-colored at maturity, unchanging when bruised; lamellulae up to three-seried.

Stipe
Stipe 1.5 cm long, 0.4-0.8 cm thick, equal or tapering to a narrowed base, stuffed to hollow in age, often with a longitudinal fold; surface sparsely fibrillose, white over a pinkish-brown ground color, conspicuously hairy at the base; partial veil absent.

Spores
Spores 4.5-6.0 x 2.0-2.5 µm, ellipsoid, smooth, inamyloid; spore print white.

Habitat
In arcs and rings in watered grassy areas; fruiting in late summer.

Edibility
Edible according to the literature; untried locally.

Comments
This small, attractive mushroom occurs sporadically in grassy areas in late summer. The pinkish cap with a wavy margin distinguishes it from other lawn fungi such as Agrocybe pediades, Panaeolus foenisecii, and Marasmius oreades.
