Habitat/range: On conifers, occasionally on hardwoods, causing a brown cubical rot. Widespread in the southern half of BC and one collection in the north at Muncho Lake (58°n). Widespread elsewhere in western North America.Basidiomata widely effuse, annual, up to 5 mm thick, when on a vertical surface forming numerous nodules, adnate, soft; taste bitter; margin narrow, white; context thin, white, soft; tubes white to cream, up to 5 mm deep; pore surface typically a distinct yellow, fading to cream and cracked into squares; pores round, 5–7 per millimetre, edges entire, thick.
Generative hyphae 2–4 μm diameter; skeletal hyphae predominate, 3–6 μm diameter, walls faintly amyloid; cystidioles fusoid, 10–14 × 3–4 μm, not pro- jecting; basidiospores allantoid, 4–5 × 1.0–1.5 μm.
Notes: The bright yellow colour and typical cracking of dry basidioma, the amyloid skeletal hyphae, and the allantoid basidiospores are the distinctive features. Antrodia alpina differs in having 2–4 pores per millimetre and its tissues stain pale pink to purplish red in koh. Diplomitoporus rimosus (Mur- rill) Gilb. & Ryvarden occurs on live and dead Juniperus in Idaho but has not yet been found in British Columbia; it is distinguished by its host preference, association with a white rot, tubular cystidia, and lack of amyloid walls in the skeletal hyphae.
