Vararia aff. rugosispora Boidin, Lanq. & Gilles

The species is characterized by a brownish basidiome, arboriform dichohyphae, simple-septate hyphae, and above all by rugose basidiospores ( Fig. 16 ). Specimens from Amazon differs in somewhat narrower basidiospores (10–12 × 5–6 µm) whereas in specimen from Gabon (the type locality) basidiospores are described as (10–)12–16(–18.7) × (6–) 7–8.2 µ m ( Boidin et al. 1980). Vararia rugosispora was also previously recorded from Iguazu, Argentina by Hjortstam & Ryvarden (1986).
