Sel. descr. & figs. - Einh. in Ber. bayer. bot. Ges. 47: 125. fig. 4. 1976; J.Favre, Assoc. fong. Hauts-Marais: 44. 1948; Noordel. in Per- soonia 10: 461-463, rig. 13. 1980.
Pileus 17-35 mm, up to 18 mm high. acutely conical with small papilla, only slightly expanding to conico-campanulate with age, with margin slightly inflexed then straight. strongly hygrophanous, when moist (greyish) sepia to grey-brown, only slightly paler at margin (Mu. 10 YR 4/4, margin 5/4-6/4) translucently striate up to half of radius, pallescent on drying to very pale brown (10 YR 7/4, 7/3) strongly silvery- fibrillose, shiny. Lamellae. L = about 30, I = 3-5, moderately distant (almost) free. triangular-ventricose up to 7 mm broad, grey then grey- pink finally tinged brown (10 YR 7/2, 7/3, 7/4 then 7.5 YR 7/4 (6/4)) with eroded, concolorous edge. Stipe 60-80 x 2.5-4 mm, cylindrical, straight, paler and more yellow than pileus (10 YR 8/4, 7/4. 8/6), browner at base (10 YR 6/4, 5/4), upper part pruinose-puberulous, downwards almost glabrous with some scattered silvery fibrils, white tomentose at base. Context relatively firm in pileus and concolorous with surface, fibrillose, paler in inner parts of stipe. Smell strongly raphanoid. Taste rancid-farinaceous to raphanoid.
Spores 10.0-13.0 x 9.5-11.0 µm, Q = 1.05-1.4, Q av.= 1.2, 5-6-angled in side-view. Basidia 25-41 x 9-15 µm, 2-, rarely also 4-spored, clamped. Lamella edge fertile or heterogeneous. Cheilocystidia, if present. 42-60 x 12-17 µm cylindrical to narrowly clavate, sometimes subcapitate. Pileipellis a cutis of radially arranged, cylindrical hyphae 2.5-10 (-14) µm wide; subpellis well-developed, consisting of inflated elements. Pigment very finely incrusting the hyphae of pileipellis, in some superficial hyphae also hale intracellular. Stipitipellis at apex with 2-5 µm wide, capitate hairs. Clamp-connections frequent in all tissues studied.
Habitat & Distr. - Solitary or in small groups on acid, peaty soils, among Sphagnum or in marshes with Salix repens, S. aurita and Menyanthes trifoliata in coastal dunes. Very rare (Callantsoog: Zwanewater). Widespread but very rare in N. and W. Europe. Aug.-Nov.
