Description: | Basidiocarp resupinate, effuse, adnate, 60-130 μm thick in section, membranaceous. Hymenial surface clay yellow, usually with numerous tiny brownish dots under the lens, smooth, occasionally cracked; margin thinning, concolorous, pruinose. Hyphal system monomitic; hyphae nodose-septate. Subiculum composed of basal layer and medullary layer. Basal layer fairly thin, with dense texture, with horizontal hyphae. Medullary layer with fairly loose texture, with variously oriented hyphae. Crystals scattered or crowded in deep subiculum. Subicular hyphae colorless, 2.5-5 μm diam., thin- or slightly thick-walled. Brownish resinous material scattered in subiculum and hymenial layer. Cystidia clavate, colorless or with brownish contents, 40-70 μm long, 8-11 μm diam. for apical parts, usually with one or more secondary septa, thin-walled, slightly thick-walled towards apices, usually covered with brownish resinous material. Basidia utriform, colorless or occasionally with brownish contents, 40-55 × 7-8 μm, 4-sterigmate. Basidiospores usually with brownish contents, cylindrical, adaxially slightly concave, smooth, thin-walled, 10-12 × 4.2-5.3 μm, IKI-, CB-. | |||

Note: | This species is very close to H. clavatum in characters, such as the clavate cystidia and the almost same-sized basidiospores. It differs from the latter in sexuality by the homothallism, and morphologically by the brownish basidiospores. | |||
