Lignosus Lloyd ex Torrend 1920, in Cui, et al., Fungal Diversity 97, 137392 (2019)

Diagnosis: Basidiocarps annual, centrally stipitate, solitary; stipe arising from a distinct sclerotium in the ground. Pilei more or less circular, white to brownish, glabrous to velutinate, usually concentrically zonate. Pore surface cream to buff; pores round to angular; dissepiments thin, entire. Context cream. Hyphal system trimitic; generative hyphae bearing clamp connections; skeletal hyphae IKI, CB–. Basidiospores cylindrical to ellipsoid, hyaline, thin-walled, smooth, IKI, CB–.

Index Fungorum NumberIF17977

Type species: Lignosus sacer (Afzel. ex Fr.) Torrend 1920

Notes: Lignosus is characterized by centrally stipitate and solitary basidiocarps arising from a distinct sclerotium in the ground, a trimitic hyphal system with clamped generative hyphae, hyaline and thin-walled, cylindrical to ellipsoid basidiospores that are negative in Melzers reagent and Cotton Blue. It occurs in tropical areas (Cui et al. 2011).
