B. berkeleyi

No, not from same tree, but on same foray. They may be
different, but we still didn’t notice blackening on the
large one.

Fronds on this are thinner — it is M. sumstinei on further consideration.
Non-blackening pieces were from a Berkeley’s.

it just doesn’t look right…

the first and forth picture look different to my concept of B. berkeleyi.
The fronds look too thin and has a lot more layers then I associate with berkeleyi and it looks to lightly colored… I have been wrong before and most likely will be wrong again, BUT… to me it doesn’t look like Berkley’s
The second and third pictures I would have no problem calling berkeleyi; did you collect them from the same tree?
if you are back in the area that you found it do collect some.

Was just a suggestion

I found Grifola frondosa and Dendropolyporus in Europe and Bondarzewia montana in Europe and Bondarzewia berkeley in America as well. I know Meripilus giganteus which is blackening as does Meripilus sumstinei. Are there any other mushrooms that look like those mentioned? I just look at the pics and something sez they look not all really right for this species but this is just a personal impression.

Not Grifola frondosa or Dendrypolyporyus umbellatus

I have found both G. frondosa and D. umbellatus here (not sure of spelling of second), the fronds on those are MUCH smaller, and pores are miniscule. They also do not have the scent this one has (rather strong).

What about Grifola or Dendropolyporus or something related?
