Description type: Non-original description

PHLEBIOPSIS GALOCHROA (Bres.) Hjortst. & Ryv. nov. comb. Basionym: Peniophora galochroa Bres. Hedwigia 35: 290,1896. Nomenclatural type: Brazil, Blumenau. Möller s.n. (S).! Fruitbody resupinate, effuse, adnate, hymenium smooth, under a lens (50 x) with indistinctly projecting cystidia, light ochraceous, subiculum creamish and and easily observed, tough, -vnsisting of thick-walled, less branched hyphae, margin not especially differentiated. Hyphal system monomitic or subdimitic (?). Hyphae of the subiculum thick-walled, in KOH and Melzer's reagent lightrefracting, in Cotton blue with the walls easily distingguishable but not cyanophilous. The hyphae are in most cases smooth but slightly encrusted ones occur, about 3-3.5 µm wide, not amyloid or dextrinoid. Subhymenial hyphae branched, less light-refracting, usually thin-walled or thickened, all hyphae without clamps. Cystidia more or less imbedded, only few projecting above the basidia, terminal, thick-walled and strongly encrusted (Metuloids), 50-60 x 710 µm. Basidia terminal, clavate or subcylindrical, 15-20 x 3.5-4.5 µm, with four sterigmata. Spores thin-walled, ellipsoid, usually 5-6 x 4 µm, non-amyloid or dextrinoid. Additional specimen: Brazil, S. Catharina, Blumenau. Möller s.n. Recently Jülich (1978) described the genus Phlebiopsis with P. gigantea as type species. Peniophora galochroa lacks the dense resinous zone so prominent between the subiculum and the subhymenium in P. gigantea, besides the cystidia are smaller and the texture softer in general. However, as the hyphae, spores and basidia are very similar in the two species we felt it natural that they were placed in the same genus.
