≡ Polyporus camerarius Berk. , Hooker’s Journal of Botany and Kew Garden Miscellany 8: 143 (1856).

Description:— Furtado (1981), Ryvarden (2004a).

Substrate: —on soil.

Distribution: — Belize, Brazil, Colombia, Guyana and Peru.

Specimens examined: — BRAZIL. Pará: Melgaço, Estação Científica Ferreira Penna, March 2007, T.B. Gibertoni w/n (URM 79317).

Remarks: —The yellowish brown basidiomata, yellow context, distinctly ornamented and subglobose to ellipsoid basidiospores [11‒13 (‒14) × 9‒12 μm] characterise the species. Amauroderma omphalodes (Berk.) Torrend (1920: 131) is similar, but has two black lines in the context and globose to subglobose basidiospores (10‒13 × 9‒12 μm).
