saw it again today in Siskiyou county,growing on willow. Apparently under-observed though. BC- CA is a good start of a range however. Lets get some more observations!

including the microscopy and a confirmation of the host plant.

sounds like it is fairly common in the PNW, and not restricted to scotch broom.

Here’s the description from the PNW key council page on Neolentinus and Lentinellus:

10a Buff or pinkish buff, usually on hardwoods

……………………………………………………………………..Lentinellus flabelliformis

CAP 0.3-3.5 cm broad, petal-shaped to fan-shaped, convex becoming flat, or somewhat depressed near point of attachment, somewhat down-curved margin at first, surface smooth, buff or pinkish buff. ODOR none or slightly aromatic. TASTE somewhat farinaceous to slightly peppery. GILLS radiating, decurrent when a short stem is present, close to subdistant, broad (up to 0.5 cm), serrate to toothed, nearly colored as cap, pinkish buff. STEM usually absent, if present short (up to 1.8 cm long), eccentric to lateral, buff to pinkish buff. HABIT usually growing in clusters, in groups, or somewhat overlapping like shingles. HABITAT on bark or barkless sticks and logs of hardwoods, rarely conifer wood. MICROSTRUCTURES spores 5-7 × 4-6 um, nearly round to short elliptical, amyloid, with minute spines.
