Fomitiporia conyana Alves-Silva & Drechsler-Santos

Material examined. BRAZIL – Amazonas • Manaus, Tropical Silviculture Experimental Station ZF-2; 02°35′ 29.0″S, 060°12′54.4″W, 92 m alt.; 21. VI.2016; M. A. Silva leg.; INPA 226229 , INPA 226230 – Roraima • Caracarai, Viruá National Park ; 01°30′36″N, 060°42′59″W, 85 alt.; 10.VII.2017; M.A. Silva leg.; INPA 286210 , 226211 • ibid., 21.VIII.2018; M.A. Silva leg.; INPA 286228 • ibid., 22.VIII.2018; M.A. Silva leg.; INPA 286212 .

Identification. As in the description by Alves-Silva et al. (2020b), our specimens present the following: basidiome perennial and applanate to convex ( Fig. 2C); hymenophoral surface with circular pores 7–8 per mm ( Fig. 2C); context homogeneous, yellowish-brown ( Fig. 2C); hyphal system dimitic, with generative hyphae hyaline, thinwalled, simple-septate ( Fig. 4C); hyphae skeletal, thickwalled, nonseptate ( Fig. 4C); basidiospores dextrinoid, hyaline, globose, thick-walled, 5–6 × 4–5 µm ( Fig. 4C).

Distribution. Fomitiporia conyana is reported for Ecuador, French Guiana, and Brazil, where it occurs in the states of Mato Grosso (Cerrado and the Xingu-Tapajos), Santa Catarina, and Bahia. There is no record from Amazonas and Roraima, and our records are the first from these states.

Fomitiporia impercepta Moreira, Robledo & Urcelay Material examined. BRAZIL – Roraima • Caracarai, Viruá National Park ; 01°30′36″N, 060°42′59″W, 85 m alt.; 11.VII.2017; M.A. Silva leg.; NPA 286215 • ibid., 10.VII.2018; M.A. Silva leg.; INPA 286214 – Amazonas • Manaus, Tropical Silviculture Experimental Station ZF- 2; 02°35′29.0″S, 060°12′54.4″W, 92 m alt.; 02.III.2016; M.A. Silva leg.; INPA 286224 • 03.III.2016; M.A. Silva leg.; INPA 286223 , INPA 286227 • ibid., 08. VI.2016; M.A. Silva leg.; INPA 286226 .

Identification. Our specimens were identified as F. impercepta based on the characters given by Moreira et al. (2017): basidiome perennial, resupinate ( Fig. 2D); hymenophoral surface with circular to ellipsoid pores, 6–8 per mm ( Fig. 2D; context homogeneous, golden ( Fig. 2D); hyphal system dimitic, with generative hyphae hyaline to slightly yellowish, thin-walled, septate ( Fig. 4D); skeletal hyphae pale brown, thick-walled, nonseptate ( Fig. 4D); basidiospores dextrinoid, globose to obvoid, Cyaline, thick-walled, 4–6 × 3–5 μm ( Fig. 4D).

Remarks.. According to Moreira et al. (2017). F. impercepta is morphologically similar to F. neotropica and part of the “Neotropical resupinate” clade, but F. neotropica is annual and F. impercepta is perennial. Fomitiporia imperceptta is also morphologically similar to F. punctata ; however, this species is not a Neotropical species.

Distribution. Fomitiporia impercepta is only reported from Argentina and French Guiana, so our records are the first from Brazil.
