Identification. Our specimens were identified as F. neotropica based on the characters given by Campos-Santana et al. (2014) : basidiome perennial, resupinate to effused-reflexed ( Fig. 3D ), hymenophoral surface with circular to ellipsoid pores, 5–9 per mm ( Fig. 3D ), context homogeneous, golden ( Fig. 3D ); hyphal system dimitic, with generative hyphae hyaline to slightly yellowish, thin-walled, septate ( Fig. 4H ); skeletal hyphae pale brown, thick-walled, nonseptate ( Fig. 4H ); basidiospores dextrinoid, subglobose to obvoid, hyaline, thickwalled, 5–7 × 4.5–6 μm ( Fig. 4H ). Remarks. Fomitiporia neotropica is similar to F. maxonii , differing mainly by the number of tube layers: in F. neotropica there are two layers, while in F. maxonii there are up to four ( Decock et al. 2007 ; Campos-Santana et al. 2014 ). Distribution. In Brazil , F. neotropica is only known from southern Brazil ( Campos-Santana et al. 2014 ), and our record is the first time this species has been found in the Amazonian region.
