Habitat: On dead conifers and hardwoods, causing a brown cubical rot.
Basidiomata sessile, reflexed, effuse, several species widely effuse, several species forming nodules, annual or perennial, up to 1.4 cm thick, adnate to separable, soft to hard, tough, corky; taste in several species bitter; margin white, cream, pale brown, or reddish brown, narrow to wide, tomentose, cot- tony, finely fimbriate; strands in some species; pileus typically elongated and narrow, some imbricate, tough, flexible; pileus surface ochreous, pale brown, cinnamon brown, becoming greyish or blackish brown, finely tomentose, glabrous; context thin, white or cream, except pale brownish yellow in A. malicola and pale brownish yellow in A. serialis, soft, cottony, fibrous, tough, corky, friable, up to 0.4 cm thick; tubes white to cream, tan, yellowish brown, resinous in two species, up to 1 cm deep; pore surface white, cream, pale pinkish buff, tan, pale cinnamon brown, pale reddish brown, greyish brown, distinct yellow, cracked into squares in one species; pores round to angular, 0.5–7 per millimetre or sinuous to labyrinth-like, 1–2 mm wide, edges entire, thick, rarely thin.
Hyphal systems dimitic. Generative hyphae 2–6 μm diameter with clamp connections, walls thin to thick, amyloid in several species; skeletal hyphae 2–8 μm diameter, walls amyloid in several species; cystidioles fusoid, some with an attenuated apex, 10–42 × 3.0–6.5 μm, walls hyaline to pale yellow, thin; basidia clavate, 12–40 × 4–11 μm, four sterigmate, except some two ster- igmate in A. sitchensis; basidiospores allantoid, cylindrical, oblong, narrowly ellipsoid to broadly ellipsoid, 3.5–14 × 1–7 μm, walls hyaline, smooth, neither amyloid nor dextrinoid.
Notes: All species share an effuse to reflexed habit and are associated with a brown rot. The context is white or cream in all except two species. The core species of Antrodia are usually recognized by their tough, corky, white to pale brown basidiomata with large pores (~ 1–3 per millimetre), and relatively large (6–14 μm long), narrowly ellipsoid to cylindrical basidiospores.
