The stipe of…

B. pallidus is typically whitish and developing brown stains in age. The cracking of the pileipellis could be due to expansion of the cap tissue — look how puffy it is. Also, I bet there is dead wood under that moss and a tree trunk can be seen nearby. This bolete frequently likes to grow out of wood: e.g., see Obs. 109206, 110201, 105345, 77332 and 73603.

Oh right…

This is the one for which the cap surface is cracked. This one does seem a bit difficult to pin down.

of my office computer, and the caps look a bit paler than with my home pc. So now I’m wondering about my “subtomentosus” suggestion. Maybe pallidus is a better idea here? But, judging from the pore diameters, this is a mature specimen. So cap color may be somewhat faded.

Any bruising reaction noted on the pores?

Any ideas on what this might be? It was pretty common at Sequanota this past fall.

Wow, I see what you mean..,

generally has a fairly pale cap color. These look like maybe B. subtomentosus.
