Notes on Taxonomy: [Edit]

Pileus cespitose-imbricate, decurrent, sometimes effused, conchate, fleshy-tough or corky, somewhat flexible when dry, 2-4 X 4-8 X 0.2-0.4 em.; surface undulate, indistinctly zonate, especially near the margin, finely tomentose or villose, isabelline with slightly darker markings; margin thin, undulate, sterile, pallid, usually becoming black as though scorched; context fibrous-corky, white, 1-3.5 mm. thick; tubes short, 1 mm. or less long, smoky-white to blackish within, mouths regular, angular, 5-6 to a mm., smoke-colored and pruinose when young, soon becoming grayish-black, edges thin, entire; spores ellipsoid- allantoid, 3-5 X 1.5-2 .5 IJ..
Occasional on dead deciduous wood in California. This species also occurs .at times on coniferous wood.

Habitat/range: On hardwoods, rarely on conifers, causing a white rot. Wide- spread in BC from the Dawson Creek area south to the BC/WA border and east of the Coast Mountains, except for several collections in the Vancouver/ Victoria areas. Widespread and common in western North America Basidiomata pileate, sessile, reflexed, or effuse, tough; pileus 1–6 cm wide × 3–10 cm long × 0.1–0.8 cm thick, often imbricate; pileus surface cream to buff, tomentose to glabrous, sometimes faintly zonate; context pale buff, up to 6 mm thick; tubes smoky grey, distinct from the context, up to 1 mm deep, lacking a dark line at the base of the tube layer; pore surface grey to black; pores round to angular, 6–7 per millimetre, edges thin, entire.
Hyphae 3–5 μm diameter with frequent clamp connections, walls thin to moderately thick; basidiospores cylindric or narrowly ellipsoid, 5–6 × 2.5– 3.5 μm.
Notes: The contrast between the grey to black tube layer and the white con- text is a good field character.
