Black bruising..

there is black bruising on the pore surface. It could be something else but I don’t think L. rugosiceps is likely. I know where they were so we’ll see what’s going on when I find some again I guess.

Your bolete isn’t L. rugosoceps but I’m not sure I can tell you what it is. I tried to post a link to my observation on Mushroom Observer about Leccinum nigrescens but I failed in that. below is the description but if you care to c…heck out that species for your bolete.

Observation: Leccinellum crocipodium (49730)
When: 2010-08-05
Collection location: Nehantic State Forest, Lyme, Connecticut, USA [Search]
Who: Bill (boletebill)
No herbarium specimen

Notes: Whatever this bolete is it’s new to me. My ID is tentitive. At first look I was sure this was going to be Boletus subtomentosus and the cap fits that mushroom exactly. Picking it threw me when I saw, looking at the stipe, this is clearly a Leccinum. In fact the stipe matches that of Leccinum rugosoceps perfectly. In every phyical aspect it looks like someone took the caps from Boletus subtomentosus and stuck them on the stipes of Leccinum rugosoceps. These mushrooms were well past prime in 100 degree heat w/ high humidity and before I could get them home for a better look the maggots were already getting the best of these.

Summary: Thanks Walt

this mushroom fits the description in RBB well but since it rotted so quickly and I’d never found it before I was hesitant to id it. It’s unique and the location is near my house so I’ll look for it again

Summary: I think you are right

But the current name is Leccinellum crocipodium.

boletebill and David Fischer pretty much said no way that these are Leccinum rugosiceps. I’m going to be on the lookout for these again this year.

Ammonia, check.

agree with walt, The staining red on the last image, tubes depressed around stipe … A little kitchen ammonia works wonders! Would have liked to see the scabers darken as the cap is cracked though…

I see

Leccinum rugosiceps commonly under oaks, usually pin oak (Quercus palustris). What makes you think this is something else?

Yeah they were under oak. I added a pic of one with the least cracked cap, if that helps.
