Hymenophore smooth, velutinous due to numerous protruding large cystidia, whitish. Margin not differentiated. system monomitic. All septa with clamps. Subiculum thin, with interwoven richly branched hyphae 2 - 3 µm wide, thin-walled to very slightly thick-walled, hyaline, often with rough surface because of slight encrustation. In the older fruit-body parts, encrustation represents an up to 1 µm thick sheath over the hypha. Subhymenium thin, with hyphae identical to those in subiculum. Cystidia subulate, 35 - 62 x 2.5 - 3.5 µm including encrustation, projecting up to 30 µm, without basal swelling, terminal or pleural, with thin to slightly thickened hyaline cell wall and outer hyaline crystal sheath covering the whole cystidium except the thin-walled, acuminate and particularly narrow, apex. Crystal protrusions on cystidium are formed like short rods that project backwards under acute angle, thus making cystidia resembling a harpoon. Basidia suburniform, 9 - 12 x 4.2 - 5.7 µm, thin-walled, with 4 sterigmata and a basal clamp, basally slightly encrusted. Basidiospores weakly allantoid, adaxial side concave, L = (4.5 -) 5.7 - 8.2 (- 8.7) µm, W = (2.0 -) 2.2 - 3.0 (- 3.3) µm, Q = (1.7 -) 2.1 - 3.4 (- 3.8), N = 178 / 4, with minute apiculus, smooth, thin-walled, hyaline, often with two oil drops (one at each pole), negative in Melzer's reagent.

C148E03C8491006AA807FC1CB2E11568.taxon	description	Description. Basidiomata annual, effused, resupinate, soft and fragile, arachnoid, thin, loosely adnate. Hymenophore smooth, hirsute due to numerous large protruding cystidia, yellowish. Margin thinning out, adnate. system monomitic. All septa with clamps. Subiculum thin, with loosely interwoven richly branched hyphae 3 - 4 µm wide, thin-walled to slightly thick-walled, hyaline and smooth. Subhymenium weakly developed, with hyphae 3 - 4 µm wide, loosely arranged, slightly thick-walled and often covered with a hyaline crystal sheath. Cystidia subulate, 65 - 115 x 4.5 - 6 µm including encrustation, projecting up to 50 µm, with or without a slight basal swelling (up to 6.5 µm diam.), terminal, with thick hyaline cell wall and an outer hyaline crystal sheath covering the whole cystidium except the tapering, thin-walled apex. Crystal protrusions on cystidium are large and mostly rounded and sparsely arranged in longitudinal rows. Basidia subclavate to suburniform, 15 - 20 x 4 - 5 µm, thin-walled, with 4 sterigmata and a basal clamp, often with a hyaline crystal collar at the base. Basidiospores broadly fusiform, L = (8.5 -) 8.7 - 11.2 (- 11.6) µm, W = 3.5 - 4.2 (- 4.4) µm, Q = (2.3 -) 2.4 - 3.0 (- 3.2), N = 31 / 1, with minute apiculus, smooth, thin-walled, hyaline, occasionally with oil drops, negative in Melzer's reagent.	en	Ordynets, Alexander, Scherf, David, Pansegrau, Felix, Denecke, Jonathan, Lysenko, Ludmila, Larsson, Karl-Henrik, Langer, Ewald (2018): Short-spored Subulicystidium (Trechisporales, Basidiomycota): high morphological diversity and only partly clear species boundaries.
