Pileus 10-25 mm broad, convex, deeply umbilicate, with involute then deflexed or straight margin, hygrophanous, when moist deeply translucently striate, pale pinkish brown or yellow-brown, sometimes with tender blue tinge near margin when young, glabrous or minutely radially fibrillose except far the granulose to minutely squamulose centre, pallescent on drying. Lamellae, L = 15-25, l = 1-5, moderately distant, adnate-decurrent, arcuate to segmentiform, white or with blue tinge then sordid pink, with contrasting, blue­black, serrulate edge. Stipe 20-50 x 1-2 mm, cylindrical, sometimes slightly broadened towards base, pale grey-yellow with faint blue tinge when young and fresh, apex sometimes minutely pruinose, downwards glabrous, polished, base white tomentose. Context concolorous with surface in cortex. Smell and taste indistinct.
Spores 9.0-11.5(-12.5) x 6.0-8.5 µm, Q = 1.3-1.7, heterodiametrical, 5-7-angled in side­view. Basidia 4-spored, clampless. Lamella edge sterile, made up of a sterile strand of cylindrical to inflated hyphae along the edge of the lamellae, bearing dense clusters of inflated terminal elements 'cheilocystidia'. Cheilocystidia 30-60 x 5-20 µm, cylindrical to clavate with abundant blue, intracellular pigment. Pileipellis a cutis with transitions to a trichoderm made up of inflated terminal elements, 12-40 µm wide. Pigment blue, intracellular in pileipellis. Clamps absent.
Habitat: in poorly manured grasslands and hay-fields; Aug.-Nov.
Distribution: Rare, but wide-spread in Europe.
