Asterodon

Asterodon Pat. 1894, in Dai, Y.C., Fungal diversity, 45, 131-343 (2010)

Diagnosis: Basidiocarps annual to biennial, resupinate. Hymenophore densely covered by spines, grey to greyish brown; subiculum yellowish cinnamon to dark brown, soft; margin arachnoid or fibrillose, in an early stage also rhizomorphic. Hyphal system dimitic, generative hyphae hyaline, thin-walled, simple septate; skeletal hyphae yellowish to reddish brown, thick-walled; setae fusoid to ventricose with sharp points, usually stellate (asterosetae), distinctly thick-walled, dark brown. Basidiospores ellipsoid, thin- or fairly thick-walled, hyaline, IKI–, CB+. On rotten gymnosperm wood, causing a white rot.

Index Fungorum Number: IF17111

Type species: Asterodon ferruginosus Pat. 1894, in Dai, Y.C., Fungal diversity, 45, 131-343 (2010)

Notes: Asterostroma Massee has asterosetae, too, but Asterodon is not related. Asterodon is evidently placed within the Hymenochaetaceae (Wagner 2001).
