is among the known substrates for this sp. Known distribution includes Ecuador, Brazil, Costa Rica, Mexico and the US. wondering whether that is enough for an ID, as the genus seems demand micro and KOH pigment extraction to confidently get to species.
It’d be really fun to try to understand the biogeography of a fungus like this. I was just reading Jack D. Roger’s treatment of the genus, and apparently he consideres concentrica and grandis to be regional subspecies, or at least closely allied species, in 1997 at least.
I have sent these off to another expert, Fred Stevens. Apparently they are bigger.
I’m not certain but I think concentrica are not Black and White, just concentric.
I’m told these have made it here from Mexico.
What makes you say D. grandis, not D. concentrica? I was under the impression that D. grandis didn’t have quite as distinct zonation as this specimen seems to.
The trees have been burned. That is not from the sporing effect.
The brown /speckled fruiting is esp. interesting. You mentioned that the cottonwoods are burned – does that account for all of the black on the wood? ..or is the black on the bark of on the 1st two photos a mat of daldinia hyphae? – added later, I did not see the spore prints in subsequent photos- perhaps that is part of the source of blackening on the bark as well.
