　Description： Macroscopic characters: Basidiocarps resupinate, effused, adnate, thin to thick, 50 μm thick in NTU-3502, 100–250 μm thick in NTU-4386, membranaceous, even pilose, densely and deeply cracked in the latter collection, cream color to olive buff, not changing color or be-coming dusky in 5% KOH; margins thining out, pruinose, concolorous or white. Microscopic characters: Context with the slight differentiation of basal and intermediate layer, opaque and obscure, strongly gelatinized, 50–250 μm thick, 1–4 stratose, 50 μm thick at the lowest stratum, 25 μm and 20 μm thick, at the upper strata, with 3 μm thick of narrow band of parallel hyphae and longitudinally intertwined hyphae in each layer; hyphae thin-walled, 1–3 μm wide, always collapse or gelatinized, with clamp connections, or slightly thick-walled aseptate, comparatively broader, up to 3 μm wide or more, densely interwoven within substratum or basal layer of context; cystidia cylindrical, straight, not encrusted, arising from the basal layer, with capillary lumen, expanding near tip, up to 5 μm in diam., and 7–11 μm long, with apex rounded obtuse, thin-walled and forming subglobose, obovoid, ovoid to oblong bodies which are easily stained by phloxine, with wall easily dis-solved in 5% KOH, cystidia protruding 30–43 μm high, 7.5–12.5 × 75–170 μm; hymenial layer 25 μm thick; basidia clavate, 3–4 × 15 μm, protruding 8 μm high, with 2–4 basidiospores; paraphyses cylindrical to clavate, 4 μm wide; young sterigmata 2 μm long; basidiopores (not attached to basidia) narrowly elliptical, 2.5 × 7 μm, smooth, thin-walled, non-amyloid.

　Note： The ensemble features of the materials from Taiwan seems more fitting the descrip-tion of Tubulicrinis gracillimus. The fructification of NTU-3502 from Taiwan sometimes is not cracked.
