Who: I. G. Safonov (IGSafonov)

No specimen available

I have a tough time placing it in any bolete clade. Doesn’t belong to the bicolor group or subvelutipes group (the pores are orange-brown). May be related to fagicola/subgraveolens/vermiculosoides/vermiculosus but isn’t either of them. Found under a black birch and hemlocks. The pileipellis, stipe and pore mouths all bruise blue and then brown. The context instantly turns blue upon exposure to air.


The stipe and pileipellis turn brown over time due to handling; the pore surface near the cap margin once yellow is now brown as well.
Compare with photo #2 — you wouldn’t even know it’s the same mushroom

I don’t recall ever seeing such a reddening in the oak-loving relative. The overall appearance, the habitat, and lack of close lookalikes other than the “chameleon” pretty much make this a open-and-shut case…
This was collected on the territory of a marvelous 18-hole golf course belonging to what used to be known as Kutsher’s Country Club. The many “island forests” scattered on the course land made it a very attractive foray site. I recall having a great time looking for fungi there in August 2004, walking from one “island” to the other across the fairways, photographing the great variety of fungi (mostly boletes, of course) there and trying to avoid the annoyed golfers. I was kind of trespassing though I was a guest at Kutsher’s hotel. I still had my film camera and was yet to buy my first digital point-and-shoot (Fuji F700). This was my first major foray where my mycological horizons got broadened. I kept visiting the place in subsequent years, and my last time there – if memory serves – was in 2011, but the amazing foray of 2004 was not to be repeated… Like the many resorts of the Borsch Belt before it, Kutsher’s was the last one go defunct around 2013. The land was sold to an Indian billionaire who razed the old hotel and built a yoga wellness center in its place. As far as I know the golf course is still there, its fate uncertain.

The reddening context…

inside the lower half of the subvelutipes stipe seems to be (at least partly) a function of age, eg. obs 288936. Younger specimens typically show a very small red area at the extreme base.

You are likely to be right. I trust your ID skill in that group are much better than mine. Moreover, B. subvelutipes is a highly variable species, according to B-R-B. Unfortunately, I don’t get enough exposure to these red and brown pored boletes where I foray…

B. subvelutipes group.
But I’m not to sure about it being B. discolor, (which I would consider in that group). I just saw lots of discolor in all stages of growth (sorry, didn’t take any pictures,) they have a lot of orange on in the cap when young, discoloring olive-brown but keeping an orange margin.

subvelutipes can go orange-brown or even olive-brown in age.

I am glad you saw humor where none was intended. Thanks! Allow me to use your quoute as my rebuttal of an old claim that I have as much humor as Anton Chigurh. :-)

To be fair,

At this point, I am no more sophisticated than calling almost anything with red or dark red-brown pores to be B. subvelutipes, so thanks for your sense of humor! I agree with you that it looks too light – especially the pores. Maybe I am just ticked off that I have not found more bicolor so far this year. Thanks for your comment.

thanks for commenting. You could be right about this one being a representative of the B. subvelutipes group, which can have a highly variable appearance. I guess the cap and stipe colors, as well as the bluing action on the outside, are favoring such an assignment, but the color of the pore mouths still make me wonder — just not red enough, though the pore surface was also yellow all around the cap margin, which is typical of B. subvelutipes.

Just for the record, could you state why this cannot me an older, possibly slightly dried B. subvelutipes? I have seen the pores start very dark brown – a rich red-black-brown. …and then they can get very red, but can’t they also darken back to an orange-brown? This one has a light cap – perhaps also environmental?
