Habitat/range: On the ground. Widely scattered in BC from Haida Gwaii and Hazelton/Smithers area south to Glacier National Park and Manning Park to southern Vancouver Island. Elsewhere in western North America, known from AK to NM.Basidiomata stipitate; stipe 6–10 cm long, 2–3 cm thick, solid, smooth, white; pileus 5–10 (–26) cm broad, circular, or frequently irregular in outline; pileus surface pale blue, greenish blue, fading to pale orange with blue tints, smooth, glabrous or suede-like; context white, fleshy, tough to brittle, over 2 mm thick; tubes 2–7 mm deep, decurrent; pore surface white, becoming apricot to salmon; pores 1–4 per millimetre, angular or round.
Hyphae 4–15 μm diameter with clamp connections; basidiospores 4–5 × 2.8–3.6 μm, broadly ellipsoid, walls weakly to obviously amyloid.
Notes: Reported to be ectomycorrhizal (Kroeger et al. 2012). The blue tints of the pileus fade, apparently on exposure to sunlight and (or) in aging. Al- though similar in habitat, size, and general appearance, A. ovinus has a white or ivory to grey pileus, lacking blue tints. Albatrellus confluens has a pinkish buff pileus that lacks blue tints (see comparison under A. confluens).
CAP 5-20 cm in diam., circular to kidneylike, convex becoming plane or centrally depressed, blue to blue-gray or blue-green; developing ochraceous, salmon, or rusty stains in age, becoming salmon pink to brick red on drying; glabrous to minutely tomentose. Margin at first enrolled, often lobed or wavy; concolorous or paler. PORE SURFACE white, developing salmon or ochraceous stains in age. PORES circular to angular, 1-4 per mm. TUBES 1-7 mm long, decurrent. STEM 5-15 cm long, 1.5-4 cm thick, solid, central to lateral, simple or branching at base, concolorous with cap. HYPHAL STRUCTURE monomitic. CLAMP CONNECTIONS present. SPORES ellipsoid to ovoid, 3.5-4 × 2.5-3 µm, thin walled, smooth, weakly amyloid.
