Brief Description:

Ganoderma citriporum Ryvarden & Iturr., in Ryvarden, Syn. Fung. (Oslo) 19:
75, 2004. Figs 1, 2

Basidiomata perennial, solitary, laterally stipitate. Pileus semicircular 7.7 cm wide, 6.5 cm long and 0.4 mm thick. Upper surface of the basidiomata dull, glabrous, sulcate and zonate, red (bark brick-20) when fresh, brown (snuff brow-17 to cigar brown-16) when dry. Margin entire, acute, cream (B-2). Context homogeneous, 0.2 mm thick, brown (clay buff 32). Tubes thin, brown (snuff brown-17). Pore surface cream, gray and citric yellow (B-2, A-1 and H-9), pores round, 4–5(–6) per mm, dissepiments thin and entire, decurrent near the stipe, 2–3 per mm.
Stipe dull, glabrous, cylindrical to irregular, 15.5 cm long, 1.1 cm diam., red (bark brick-20) when fresh and brown (snuff brow-17 to cigar brown-16) when dry, context of stipe homogeneous, brown (cigar brown-16), with cuticle delimited. Hyphal system dimitic; generative hyphae with clamps, hyaline, thin-walled, 2–3 µm diam.; skeletal hyphae yellow, thick-walled to solid, arboriform, 3.5–5 µm diam. Basidia not seen.
Basidiospores oblong, truncate, double-layered, pale brown, finely ornamented,
8–9(–10) × 5–6 µm.

COMMENTS: Previous studies of G. citriporum were based on material collected in
Venezuela (Ryvarden 2004). The species is characterized by the irregularly shapedstipe, the citric pore surface and oblong basidiospores (9–10 × 4–5 µm). It is macroscopically similar to G. australe, the latter differing by the larger basidiospores(7–12 × 5–8 µm). The materials SP 211487 and URM 79486 differ macroscopically from the description of Ryvarden (2004) by the cream to white color of the pore surface and slightly larger pores.
DISTRIBUTION: Venezuela (Ryvarden 2004) and now proven to occur in Brazil.
SUBSTRATE: on dead wood.
