than B. bicoloroides. My understanding is that this species has only recently been described, and that its range is not well understood. So perhaps the reported variability in macro-traits will change as more is learned.

I am pretty “fresh” Dave so….

all input or suggestions are more than welcome. I am basing my ID on other B. bicoloroides found together, in this area at the same time. Inrolled margin, no or slow bruising and red stipe. Next year I can save some material and do more tests. Still need a good scope, this old one I have isn’t very good. The turtles were eating the Boletes in this area.

the apex of the stipe is reticulate. The pinkish staining of the cap context (presumably the result of some critter nibbling) seems very interesting. No mention is made of this pinkish staining in the bicoloroides descriptions I have read.
