Remarks (public):Like in other species of sect. Papillata, such as E. ameides and E. sericeum, the habit of E. vernum varies from slenderly mycenoid (cucullatus-type) to rather robust tricholomatoid. In the Netherlands, it is mostly the slender type that has been found.

Pileus 10-60 mm, acutely conical then expanding, finally (plano-) convex usually with conical papilla, with slightly involute margin when young, strongly hygrophanous, when moist dark sepia, blackish brown at centre, paler at margin (NIL,. 10 YR 3/3, 3/2; 2.5Y 3/2, 4/3, rarely 6/4; margin 10 YR 5/4, 6/4; 5 Y 6/6), translucently striate at least at margin, but up to centre in small, thin-fleshed specimens, pallescent on drying to golden-brown or grey-brown, ochraceous-grey or isabella (2.5 Y 6/4 to 6/6; 10 YR 6/4, 5/4), glabrous, shiny. Lamellae, L = 19-40, I = 1-3(-5), rather crowded, adnexed to almost free, ventricose, up to 7 mm broad, pale grey-brown then brown-pink or rusty-brown (10 YR 6/4; 7.5 YR 7/4, 6/4), with concolorous, entire or eroded edge. Stipe 20-67 x 2-7 (up to 10 at base) cylindrical usually slightly to distinctly broadened at base, sometimes compressed with groove, concolorous with pileus or paler and with ochraceous tinge, pruinose at apex (rarely pruinose all over in young specimens), glabrous, innately fibrillose, not striate, white tomentose at base. Context pale brown in pileus and stipe, brittle. Smell none or faintly herbaceous. Taste mild.
Spores (8.0-)9.0-11.5 (-12.0) x 7.0-9.0(-9.5) µm, Q = 1.1-1.4, Q av.= 1.25, 5-6-7-angled in side-view with dihedral base. Basidia 27-50 x 8.5-12.5 (-16) µm, 4-spored, clamped. Lamella edge fertile. Cystidia absent. Pileipellis a cutis of radially arranged, cylindrical hyphae, 4-11 µm wide. Pigment coarsely incrusting in pileipellis and upper pileitrama. Clamp-connections abundant in hymenium, elsewhere rare or absent.
Habitat & Distr. - Solitary or in groups, terrestrial in grass or in grasslands on sandy soil, preferably near coniferous trees (Pinus, Juniperus). widespread but rare. Strictly vernal. March-May.
