Name: Polyporus guianensis
Citation: Polyporus (Basidiomycota) in the Brazilian Amazonia, with notes on Polyporus indigenus I.J. Araujo & M.A. de Sousa and P. sapurema A. Møller
COMMENTS: The brownish, laterally to centrally stipitate basidiomata, the striate pileus surface, and the large pores (1–2 per mm) are typical for this species. Polyporus leprieurii and P. tricholoma are similar, but the smaller pores (5–8 per mm and 9 per mm, respectively), smaller basidiospores (4.5–7 × 2–2.5 μm and 6–7 × 2–3 μm, respectively) and the pileus with ciliate margin in P. tricholoma distinguish this latter species from P. guianensis.
KNOWN DISTRIBUTION: Tropical Asia, South America (Nuñez & Ryvarden 2001) and Africa (Ryvarden & Johansen 1980). In the Brazilian Amazonia, recorded in the states of Acre, Amazonas and Pará (Gomes-Silva & Gibertoni 2009).
SUBSTRATE: on deciduous wood.
