Remarks (internal):This species has been reported several times from Argentina (Galan et al., 1993, sub Grandinia; Urcelay et al.,1999: Greslebin & Rajchenberg, 2000). There is also a specimen from Brazil (Hjm 16347) deposited in Kew. Irpex fimbriaeformis Berk. & M.A. Curtis, originally described from USA (Pennsylvania), seems to be extremely similar if not the same. The holotype (Michener 3762) is filed in Kew. See further Gilbertson (1965) and Ginns & Lefebvre (1993).
Specimen: Estado Aragua, Parque Nacional Henri Pittier, Rancho Grande Research Station, on hardwood, 21.II.2000, L. Ryvarden 42276 (O and duplicate in Hjm Priv. Herb.).

Description of Venezuelan specimen: Basidiome resupinate, effuse, adnate. Hymenophore pale ochraceous, distinctly hydnoid to almost irpicoid with dense, mainly flattened aculei and with small outgrowths along the side, approximately up to 2 mm long. Hyphal system monomitic; hyphae distinct, somewhat thickwalled, 2.5-3.5 µm wide, irregularly interwoven in the subiculum, more or less parallelly arranged in the middle of the aculei; projecting hyphae in the aculeal apices often incrusted, all hyphae with clamp-connections. Cystidia of two kinds, 1) capitate, 25-50 µm, usually with an apical cap of resinous matter 2) thin walled, acute, with one or more constrictions, 20-35 µm long, sometimes difficult to find or may be lacking. Basidia subcylindrical, constricted, 15-20 x 4-5 µm, with 4 sterigmata and a basal clamp-connection. Spores broadly ellipsoid to almost globose, smooth, thin-walled, (4.5-)4.75-5 x (4.25-)4.5-4.75 µm.
