Aurificaria indica

Aurificaria indica (Massee) D.A. Reid 1963, in Dai, Y.C., Fungal diversity, 45, 131-343 (2010)

Diagnosis: Fruitbody Basidiocarps annual to biennial, pileate, solitary or a few imbricate in clusters, woody hard and light-weight when dry. Pilei flabelliform or dimidiate, projecting up to 5 cm, 8 cm wide and 8 mm thick at base. Pileal surface dark brown to greyish brown, glabrous, azonate; margin obtuse, curved down when dry. Pore surface yellowish brown to dark brown, more or less glancing; pores angular to round, 6–8 per mm; dissepiments thin to fairly thick, entire. Context yellowish brown to umber-brown, corky, up to 3 mm thick, covered by a distinct cuticle, a thin context present between tubes if biennial. Tubes dark brown to umber, hard corky, up to 5 mm long. Hyphal structure Hyphal system monomitic; generative hyphae simple septate; tissue darkening but otherwise unchanged in KOH. Context Generative hyphae pale yellowish to golden yellow, thin- to slightly thick-walled, rarely branched, with frequent simple septa, sometimes collapsed, 4–8.5 μm in diam. Hyphae in the cuticle brown, thick-walled to subsoild, agglutinated. Hyphae in both context and cuticle regularly arranged. Tubes Tramal hyphae varying from pale yellowish and thin-walled to yellowish brown and fairly thick-walled, occasionally branched, with frequent simple septa, parallel along the tubes, 2–5 μm in diam. Hymenial setae absent; basidia broadly clavate, with four sterigmata and a simple basal septum, 14–17×5–6.5 μm; basidioles barrel-shaped, smaller than basidia. Spores Basidiospores broadly ellipsoid to ellipsoid, dark to olivaceous brown, thick-walled, smooth, IKI–, CB–, (4.8–) 5–5.8(–6.2)×(3.9–)4–5(–5.7) μm, L=5.45 μm, W= 4.62 μm, Q=1.13–1.22 (n=60/2).

Index Fungorum Number: IF326834

Notes: Remarks Aurificaria indica has an annual habit, and its hyphal structure is monomitic; these characters make it resemble Inonotus, but the main difference is the dark to olivaceous colour of the basidiospores.
