Notes on Taxonomy: [Edit]

Habitat/range: In the late autumn, on the ground especially along the Pacific coast under Tsuga heterophylla and Picea sitchensis; from Haida Gwaii (Kroeger et al. 2012), Vancouver Island, and two collections from Manning Park. Elsewhere in western North America, known from WA, OR, and CA.

Basidiomata, solitary, odour none or faintly anise-like, taste none or some- what bitter; stipe central, 5–9 × 1–2 cm, solid, surface white, pallid to grey, becoming mottled with rusty to ochreous spots; pileus 4–10 cm diameter, circular to somewhat flabelliform (fan-shaped), broadly convex to centrally depressed; pileus surface white to avellaneous (pale pinkish grey), becoming mottled with yellow tints, dry, dull, smooth, appressed tomentose to rather scurfy to slightly squamulose; context 0.2–1 cm thick, white, staining yellow when cut; tubes decurrent, 3–4 mm deep, white, staining yellow; pore sur- face white, staining yellow; pores angular, 2–3 per millimetre, edges becom- ing thin and lacerate.
Hyphae (4–) 8–15 (–30) μm diameter with simple septa; basidiospores broadly ellipsoid, some subglobose, 5.0–5.6 × 3.6–4.2 μm, walls hyaline, thin, smooth.
Notes: One of a few polypores that is ectomycorrhizal (Kroeger et al. 2012). Basidiomata might be confused with young basidiomata of A. ovinus; A. ovi- nus differs in having the pileus surface grey, greyish white to pale ivory, pale cream to pale tan, that stains yellow and smaller basidiospores. Basidiomata
of Polypus dispansus (Lloyd) Audet are multipileate with clusters up to 35 cm diameter and composed of numerous golden yellow, petal-shaped pilei with stipes arising from a common base. It occurs on the ground in Idaho and east- ern Washington, is associated with various live conifers from Abies to Thuja, and causes a brown cubical rot. It has not been found in British Columbia.
