Habitat/range: On a Pseudotsuga menziesii log on Vancouver Island (Cow- ichan Lake). Elsewhere in western North America, on confirs in MT, ID, and OR.Basidiomata effuse, perennial, soft, drying brittle, chalky or crumbly, up to 15 mm thick, tissues pale pink to purplish red in koh; taste bitter; margin white, narrow; context white, distinct from tube layers; tubes near white to cream, stratified, each layer up to 2 mm thick; pores round to angular, 2–4 per millimetre, pore mouths thin and typically lacerate; pore surface bright yellow.
Generative hyphae 3–5 μm diameter with clamp connections, walls hyaline, thin; skeletal hyphae predominate, 3–5 μm diameter, walls not amyloid; cys- tidioles scattered, 12–15 × 4–5 μm, fusoid, with acute apices, not projecting; basidiospores ovoid, some narrowing toward the base, 4–5 × 2.0–2.5, walls hyaline, neither amyloid nor dextrinoid.
Notes: Antrodia xantha is also yellow and of a similar texture, but it differs in having 5–7 pores per millimetre, weakly amyloid skeletal hyphae, allantoid basidiospores, the dried pore surface often cracked into squares, and tissues that do not stain weakly pink in koh.
