Fomitiporia neotropica Campos-Santana, Amalfi, R.M. Silveira, Robledo & Decock

Material examined. BRAZIL – Amazonas, Manaus • Tropical Silviculture Experimental Station ZF-2; 02°35′ 29.0″S, 060°12′54.4″W, 92 m alt.; 04.III.2016; M.A. Silva leg.; INPA 286225 • Adolph Ducke Forest Reserve , 03° 00′27.0″S, 059°53′59′59.0″W, 92 alt.; 27.I.2008; M.A. Jesus leg.; INPA 286220 – Roraima • Caracarai, Viruá NationalPark ; 01°30′36″N, 060°42′59″W,85malt.; 11.XI. 2009; M.A. Jesus leg.; INPA 286216 .

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.
