The following description is based on a specimen from Brazil, Hjm No. 16481 (K). BASIDIOME easily separable from the substratum, resupinate to subpileate, (often extremely variable in size). HYMENOPHORE at first tuberculate to more or less subporoid, then aculeate to distinctly hydnoid; aculei flattened to more rarely conical, 5-7(-10) mm long, olive-green to mostly sulphure-coloured or reddish-brown. HYPHAL SYSTEM monomitic; generative hyphae 2-5 µm wide, hyaline to subhyaline, thin-walled; other hyphae 4-8 µm wide, thick-walled and with a slight cyanophilous reaction; aculeal hyphae mostly parallel arranged and forming a rather dense trama. All hyphae without clamp-connexions: CYSTIDIA absent. BASIDIA subclavate, thin-walled, 13-16 x 5(-6-7) µm, with four sterigmata and without a basal clamp-connexion. SPORES elliptical, thick-walled, yellowish-brown, 4-5(-6) x 2.25- 2.75(-3.5) µm, with a weak or, after 1-5 minutes, a rather strong dextrinoid reaction, distinctly cyanophilous. |
