Description: Pileus $-12 (13) mm broad, hemispherical to convex, mostly with weak umbo, with dellexed to straight margin, translucently striate up to half the radius when moist, opaque when dry, not entirely white, but with very slight grey orochre tinge when moist. Lamellae moderately distant, L= about 20, 1 = | 3, strongly arcuate-decurrent, white, with entire, concolorous edge, well-developed, but sometimes not entirely reaching the margin of pileus. Stipe 15-45 (50) x 0,8-1,2 mm, eylindrical, hyaline, greyish white, very finely pruinose-floccose all over (lens), Smell and taste indistinet, Spore print white, Spores 5.5 7.0 x 2,5 4,0 um, E 1,5-1,8,0- 1,6-1,7, broadly ellipsoid to ellipsoid, with large apiculus. Basidia 4-spored, clavate. Lamella edge fertile. Hymenial eystidia absent. Pileipellis a cutis Basidia 4-spored, clavate. Lamella edge fertile. Hymenial eystidia absent. Pileipellis a cutis of diverticulate, 4.0-11 pm wide hyphae, with few to abundant finger-like or cystidioid excrescencies, 3.0-15 (25) x 1.5-3.5 um, sometimes resembling pilcocystidia. Subpellis a compact layer of short, inflated elements, 12-45 x 6.0-18 um with slightly thickened, refractive, hyaline walls. Stipitipellis a cutis with abundant cauloeystidia, 10 35 x 7.0 10 um, clavate to cylindrical, sometimes slightly inerusted; in lower third of stipe tapering hairs present, 60-90 x 4,0-7,0 pm, with slightly to distinetly thickened walls. Clamp-connections abundant. Chemical reactions: Neither spores nor tissues amyloid or dextrinoid. Ecology: On litter of Coyptomeria japonica in a garden and in ./uniperus serub.
