Australicium

Australicium Hjortstam & Ryvarden 2002, in Gorjón, Studies in Fungi 5(1), 167 (2020).

Diagnosis: Basidiome resupinate, adnate, hymenophore smooth, usually pale brown, subiculum distinct, brownish to brown, tomentous. Hyphal system monomitic, subicular hyphae thick-walled, yellowish to brownish, with simple-septa even single or double scattered clamps may occur, subhymenial hyphae hyaline, thin or with thickened walls, simple-septate. Cystidia or hyphal ends rare, hyaline, thin-walled, not encrusted. Basidia subclavate, slightly constricted, with 4-sterigmata, with a simple basal clamp. Basidiospores ellipsoid to cylindrical, smooth, thin-walled, hyaline, IKI–, CB–.

Index Fungorum Number: IF28652

Type Species: Australicium singulare (G. Cunn.) Hjortstam & Ryvarden 2002

Notes: Australicium was created to accommodate Corticium singulare, a species with a distinct brown and tomentose subiculum composed of brownish thick-walled hyphae (Hjortstam & Ryvarden 2002). It is closely related to Phanerochaete but differing morphologically in the brown subiculum.
