Observation 76891: Boletus subvelutipes group

When: 2011-09-14

Collection location: Monticello, New York, USA [Click for map]

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

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?
