Distribution: So far, only found in Washington and Oregon
Spores: smooth ellipsoid spores (15.5--21.5 x 7.5--10.5 µm
Conservation Status: Not of concern
Pseudaleuria quinaultiana is a rare cup that looks somewhat like Aleuria aurantia. It differs in being more saucer-like than cup-shaped, having a more reddish fertile surface, occurring in ones or twos rather than large groups, having smooth ellipsoid spores (15.5--21.5 x 7.5--10.5 µm, and fruiting in spring rather than fall. The species was described from a collection made near Lake Quinault, in the southwestern portion of the Olympic Peninsula, and it has been found primarily in old-growth forest with Sitka spruce, western hemlock, and Douglas-fir. As far as we know, it occurs only in Washington and Oregon but, because seemingly suitable habitat is present from northern California to B.C. and southeast Alaska, it could well occur in those areas too.
