Micro photos show material scraped from partially dried fb and mounted in Meltzer’s. Asci appear to be inamyloid, which I believe points away from Peziza.

I doubt I’ll return to the collection site, at least not within the foreseeable future… 150 miles from my home. I don’t think the specimen was washed-out by rainfall. Only one period of rainfall in this area during the preceding week, and I figure this caused the fruiting. Material seemed structurally sound… not old and washed-out.

Spores appear to match Otidea.

The fertile surface seems to be a problem within the described Otidea, Dave. I think it would be good to have a voucher collection of this if you come across it again. It might also be a very old rain-battered specimen with the color washed out of it? Hard to decide when the original is that far away.

It has the “split/pinched goblet” appearance.

Also, the side opposite the pinch in slightly elongated. Seems to match with O. onotica, except the inner surface of this specimen is white.

usually looks like it grew around a pencil or twig. It is usuallly pinched at the base, expands near the center, and collapses back to a central point at the top.

Having said that, this looks similar to an Otidea, but not the normal growth habitat. Maybe something new?
