Description:— Furtado (1981 , as A. rude var. intermedium J.S. Furtado 1968: 251 ), Ryvarden (2004a) . Substrate: —on soil. Distribution: — Brazil , Colombia , Guadalupe , Martinique , Paraguay and Puerto Rico . Specimens examined: — BRAZIL . Pará : Melgaço , Estação Científica Ferreira Penna , February 2007 , T.B.

Additional specimen examined: — AUSTRALIA : Tasmania , w/d, Gunn w/n [BPI 237189, type of A. rude (Berk.) Torrend (1920: 18) ]. Remarks: — Amauroderma intermedium is characterized by the dark brown to black pileus, context with two black lines and subglobose, finely ornamented basidiospores (9‒11 × 7‒9 μm). This species is currently considered a synonym of A. rude ; however, based on the analysis of the type of A. rude , on the characteristics described by Furtado (1981) and on geographic distribution, we preferred to keep these two taxa as distinct species.
