I could see that it was small…

it looks like a miniature version of our mirabilis.

Roots in a blender is the answer

I don’t know if Boletellus chrysenteroides is MR, saphrobic or both but I’m sure the answer is out there. I don’t read professional journals but any number people are harvesting rootlets with MR and examining the DNA and checking against gen bank for known species sequences to determine the diversity of MR without ever seeing a mushroom. I’m sure Steve Trudell could shed some light there. Pretty cool and something I’ve wondered about for a couple decades. Tom V sent me to a webpage on the American Chesnut studies that does just that and they’ve already identified 145 MR species for that one tree species. I don’t know if Boletellus chrysenteroides is among them. BTW B. chysenteroides is a tiny bolete here in the NE usually less than 2 or 3 inches tall with a cap less than an inch.

it reminds me (in its macro gestalt) very much of our local CA Boletus mirabilis, which also prefers to grow with well-decayed wood.


But does the MR mycelia merely grow up into the downed decayed wood or are these bolete sp. really functioning more as a woodrotting species?

that, I guess, is the question. or at least one of ’em. ;)

About a quarter of the time I find this on dead decayed logs

and the rest of the time just growing from the forest floor as if a normal bolete but if you pull it up carefully there’s often a bunch of woody debris at the base of the stipe which, i guess, begs the question, “Is it mycorrhizal?”

What habitat do you normally find this in?
