Basionym: Fomes tropicalis Cooke, Grevillea 15:22,
1886 (K:).
FRUITBODY perennial, resupinate, widely effused, up to 3 cm thick, woody hard when dry. PORE SURFACE grey to pale brown, pores small, 6-8 per mm, margin wide, glabrous and smooth, grey to black and then in section with a thin cuticle, often somewhat folded, especially wide in upper parts of specimens growing on sloping substrates and the fruitbodies may then look almost nodulose with badly developed pilei, tubes pale brown, weakly zoned, up to 20 mm deep. CONTEXT pale µm ber brown, very thin to lacking.
HYPHAL SYSTEM trimitic, generative hyphae thin-walled, hyaline and with clamps, difficult to find in dry fruitbodies, skeletal hyphae dominating, solid to thick-walled, 3-4 µm wide, faintly tinted in KOH, slightly dextrinoid in Melzer's reagent. CYSTIDIA not seen. SPORES hyaline, ellipsoid, thin-walled and apparently smooth, amyloid, 3-4 x 2-2.5 µm , measured in 2% KOH as they are collapsed in dry specimens seen by us and difficult to inflate in Melzer's reagent.
HABITAT. On deciduous wood. DISTRIBUTION. Tropical America, known from Central America and British Guiana.
REMARKS. The species is closely related to W. gloeocystidiata but is without the gloeocystidia of the latter.
