Description: | Basidiocarp resupinate, effuse, ± adnate, 120-300 μm thick in section, membranaceous. Hymenial surface cream-colored, smooth, extensively cracked; margin thinning, concolorous or paler, filamentose. Hyphal system monomitic; hyphae nodose-septate. Subiculum with loose texture; hyphae horizontal and ± glued together next to the substratum, variously oriented elsewhere, colorless, fairly rigid, 3-6 μm diam., with 0.5-1 μm thick walls. Encrusted cystidia not abundant, mostly immersed, colorless, 40-90 × 10-15 μm (with encrustation), with 0.4-1.2 μm thick walls. Basidia utriform, 35-50 × 6.5-8 μm, 4-sterigmate. Basidiospores cylindrical, adaxially flattened or slightly concave, smooth, thin-walled, 12-14 × 4.5-5.5 μm (holotype spore-print: X = 13.22 ± 0.59 × 5.00 ± 0.13 μm, n = 30), IKI-, CB-. | |||

Note: | This species is reminiscent of Hyphoderma leptaleum (Ellis & Ev.) Ginns, owing to the presence of encrusted cystidia and the similar size of basidiospores. However, H. leptaleum has thin-walled subicular hyphae and longer basidiospores (14.6-15.4 × 4.4-4.8 μm), according to Ginns (1992). | |||
