Phil, I agree the reticulations…

on B. variipes are generally mose distinct than what is seen in this obs. But this looks like a button that may not have developed normally. I think this is why it’s difficult to get a read on an ID here.

Don’t think so based on the stipe. Yours is coarsely reticulated with raised ridges and pits, whereas B. variipes according to Bessette and Roody “is distincly reticulate or sometimes inconspicuously so”. Big difference. Next time you find one check for beads of fluid on young specimens. You can also try some chemical test on the caps.

Well, I wouldn’t bet any money…

on a B. variipes ID. But a few things remind me of this type… shape of fruit body, gray cap, looks to be non-staining, and my take on the stipe is coarsely reticulate. I have not ever IDed A. subflavidus; looks to be distributed south of my area. I did read that the taste is bitter, which would immediately seperate this type from B. variipes.

No, I didn’t.

You could very well be right— A. subflavidus was a bit of a shot in the dark. I collected this about 6 months ago and don’t remember too much else about it. Although I read the descriptions for these two mushrooms carefully again, and it looks more typical of A. subflavidus to me, since it is so white and has almost a pitted stipe. But if you are familiar with A. variipes and think this looks typical for that, I’ll take your word for it.

Rob, did you taste this mushroom?

The reason why I ask is that, to me, this looks like a small specimen of Boletus variipes, which would have a mild flavor. A. subflavidus (which I have not ever IDed) is reported as tasting bitter.
