Ceraceopsis verruculosa Hjortstam & Ryvarden
Basidiome resupinate, membranous, cream to pale brown, detachable, margin indeterminate. Hyphal system monomitic to pseudodimitic with simple-septate hyphae. Subhymenial hyphae thin-walled, hyaline, 3–5 µm in diam., subicular hyphae straight, thick-walled, yellowish in KOH, Melzer’s reagent, and CB, 2–3 µm in diam. Hymenium a palisade of basidia, cystidiols, and hyphidia. Cystidiols clavate or with a median constriction, 20–30 × 5–10 µm, some with an apical papillae. Hyphidia not or with few sparse ramifications. Basidia clavate, 25–30 × 5–8 µm, with four sterigmata but difficult to discern because basidia collapse after discharging basidiospores, simple-septate at the base. Basidiospores ellipsoid to broadly ellipsoid, 6–8(–9) × 4–5.5 µm, rough, slightly thick-walled, with a prominent conical apiculus, IKI–, variably cyanophilous ( Fig. 1 View FIGURE 1–4 ).
The specimen agrees with C. verruculosa in its membranous basidiome, simple-septate hyphae, and rough cyanophilous basidiospores but differs in the presence of cystidioles and hyphidia that were not mentioned in the original description ( Hjortstam & Ryvarden 2007b). The species was known from the type locality in the Venezuelan Amazon.
