комментарий: in Smith, Smith & Weber has spores “26-34 × 13-15 microns, apiculi absent or mere pads at the eds of the spores.” But the description also notes “the taxonomy of the fungi related to G. gigas in North America is in a state of change, all the variants are basically similar macroscopically.” While thia obs. looks like what I have collected as G. gigas in the Cascades (and Blue Mountains, which would be to the east of this site), maybe the true G. gigas is a more limited species. And what I have been collecting for the last 30 years may be more of a species complex than a single species.
