Mycol. 1:336, 1821. -Basidiocarps annual, sessile or effused-reflexed. dimidiate. tough-corky, up to 12 cm wide; upper surface of pileus mattedstrigose to glabrous, buff to light brown, usually zonate and shallowly sulcate; pore surface light buff to darker brown with age, the pores variable, circular or radially elongated and up to 1 mm in diam, daedaleoid, or with dissepiments splitting to form a radially lamellate hymenophore; context pale buff to brown, firm-corky,_azonate, up to 20 mm thick; tube layer concolorous and continuous with context, up to 10 a thick.
Hyphal system trimitic; contextual generative hyphae thin-walled, with clamps, hyaline, with occasional branching. 2-6 µm in diam; contextual skeletal hyphae thick-walled, nonseptate, with rare branching. 4-7 µm in diam; contextual binding hyphae thickwalled. non-septate. much-branched, 2-4.5 µm in diam; tramal hyphae similar.
Cystidia none; but branched dendrohyphidia present, thin-walled, not encrusted. 2-3 µm in diam.
