Observation 49344: Boletus separans Peck

When: 2010-07-20

Collection location: Seven Mile Lake Trail, Forest Co., Wisconsin, USA [Click for map]

Who: Steve Nelsen (sfnelsen)

No specimen available

I called it “Boletus A” in my notes, but was told it is probably a Xerocomus. I admit to liking Smith’s classification of Boletus much better than the more modern one. Smith has quite a bit to say about why he refused to use Xerocomus, but I suspect that it boils down to being different from Singer. Cap of the one shown in the thumbnail is 11 cm stem 14 cm x 2.5 at top, stem shallowly reticulate lower than 3 cm. pores ~ 9 mm deep. There were many of these along the trail, but I only looked closely at this one. Most were heavily eaten by something. Spores brownish, pointy ends, ~11-13 microns x ~4.7 microns, NH3 & NaOH slowly orange on cap cuticle, yellower on flesh. I did not try it on the stipe.
