Collection location: Jacobsburg State Park, Belfast, Pennsylvania, USA [Click for map]

Who: Dave W (Dave W)

No specimen available

Notes:
There were numerous hard-fleshed buttons on the ground near large oaks of what I believe is some sort of polypore. These two showed a lot of vertical development.

yup, frustrating that you can’t easily go back and confirm.

still, gotta love MO, where we all get to put the pieces together to make a better sharper puzzle picture.

I agree Debbie.

Probably berkeleyi that will eventually evolve along with a longer than usual attachment to the substrate. Or maybe fronds will emanate horizontally…? I wish this was closer to my usual stomping grounds.

fair enough Dave.

I agree that these forms are awfully vertical for a broad rosette of a polypore!

Still, seems like our best working ID for now.

Not sure this mystery is solved.

But at least B. berkeleyi is a believable proposal. Young fruit bodies of these don’t exhibit any consistent shape/form. They tend to begin as hard-fleshed bumpy blobs. Still, the ones seen in this obs show quite a bit of vertical development, even for the shape-shifting berkelyi.

Here’s an example from last year showing the initial “blob” and what it evolved into after 10 days, obs 243064. The 10th day version is like an intermediate form; the fronds continue to thin out and form fairly well-formed semi-circular shelves that grow to an impressive size. I didn’t get any additional photos after day 10. I think I remember someone cut a big chunk off it.

that’s great that you could follow them through their growth.

thanks for solving this mystery!

Young and old

I do not see the young and old ones together but there are 3 spots where I see it every year and I go to them often and get to see it both when it is starting out and then later when it is several feet wide. I have even been past one collection when people were calling them white chanterelles, even though we do not get them here. The only thing that looks similar to me when young is the black staining polypore but it still stains black but often a little slower and it also tends to have more cream in tit and it tends to start later in the season.

huh!

I would never have guessed berkeleyii! I assume that you have found both young and older examples together before, John? Talk about knowing mushrooms in all of their guises!

Hi Martin and John.

These are as big as they probably look, ~8-9 inches. Almost certainly from buried wood/roots. Berkelyi makes about the most sense so far, especially since this was near a large oak.

I saw what I know is a young berkelyi today.

If these are on wood and not as big as they look, try this for comparison:

I’ll probably not get back to this spot this year. But I believe Eastern Penn Mushroomers may have at least one foray at this location.

can you let them grow up a bit and go back?

That’s what I thought at first, Ryan…

“Hypomyces”. But these were not hypomycized Amanitas, which are slimy and with soft/brittle context. These were rigid, like Ganoderma buttons, and the white on the surface did not rub off. There were other less notable examples in the area… smaller versions on the ground near dead trees.
