Descripción original Description: Pileus 1.5-10 (14) mm broad, hemispherical or campanulate-conical when young, expanding to convex, with a distinet umbo at centre especially when young, less distinet when old, with involute to inflexed, then + straight, irregular to slightly crenulate margin, hygrophanous, translucently striate up to at least half the radius, white, old carpophores sometimes with watery greyish tinge at centre; radially finely rugulose. finely tomentose, sometimes almost strigose at margin. La» mellae distant, L=9-15,1= 0-2, arcuate, broadly adnate or more frequently shortly but distinetly decurrent,well-developed, reaching the pileus margin, slightly intervenose when old, white, with concolorous, finely pruinose edge. Stipe 15-40 (50) x 0.3-0).7 mm, cylindrical, slightly broadened at apex, finely pruinose edge. Stipe 15-40 (50) x 0.3-0).7 mm, cylindrical, slightly broadened at apex, finely pruinose edge. Stipe 15-40 (50) x 0.3-0).7 mm, cylindrical, slightly broadened at apex, cylindrical to slightly broadened at base, hyaline, white, entirely finely tomentose-strigose, with distinet, up to 1 mm long rhizoids at base. Context very thin, white. Smell indistinet, fungoid. Taste mild. Spores (7.0) $8.0-11 (12) x 2.2-3.2 um, E = (2.7) 3.0--5.5, Q = (2.9) 3.2-3.8 (4.2), cylindrical to cylindrical-ellipsoid, rarely suballantoid, thin-walled, hyaline. Basidia (18) 20-27 x $.5-7.0 um, 4- spored, clavate. Basidioles 12-24 x 2.5-7.0 um, cylindrical, clavate. Cheiloeystidia (16) 18 23 (27) x 4.5 7.0 pm, cylindrical, elavate, subfusoid, subutriform, often irregular, slightly tuiek-walled. Hymenophoral trama made up 00 3-30 pm wide, eylindrical, ellipsoid or fusiform, thin- to slightly thick-walled elements, Pileipellis a cutis of radially arranged, + slightly thick-walled, diverticulate, up to 2.5-10.0 pm wide hyphac; diverticulae digitate, obtuse, up to 8.5 x 2.5 um. Pileocystidia rather frequent to scattered, 10,019 x 2.0-4,0 um, clavate, subutriform, subeylindrical, sublageniform, irregular, sometimes branched. slightly thick-walled. Stipitipellis a cutis, of parallel, eylindrical, slightly thick-walled, up to 5 pm wide hyphae. Cauloeystidia 12-25 x (3.0) 3.5-5.0 (6.0) tum, evylindrical, clavate, irregular, sometimes monilifirm, slightly thick-walled. Clamp-connections present. Chemical reactions: Neither spores nor tissues amyloid or dextrinoid. Ecology: Saprotrophie, often in large groups, on needles of Picea, less frequently Pinus and Abies.
