Peziza repanda does fit, i have found it and it does have a wrinkled center.

I think P. repanda

may be the one, Irene. In particular, the wrinkled center of the cup (which is what caused me to guess “Disciotis”) seems to be a fairly distinctive macro trait for Peziza. (In my limited experience with observing Pezizas, they are mostly smooth capped.) Also, as you say, the pale outer surface. Kuo lists habitat as including “on the ground in soil that is rich with decayed wood.” This matches very well the habitat where I found this specimen. Lastly, the attachment to substrate was under the center of the cup.

How about

this cup was found. Second and third pics represent specimen as observed on 5/5. I think this is the exact same cup as obs 44852; otherwise it is from the same grouping. Spore size supports Peziza. Interesting feature of elliptical spores is that one part of the surface appears to be pushed in, so that when the indentation is viewed head on, the spore looks like a bowl. A few of them where the indentation is viewed in profile look like bent sausages.

Seems like maybe the main

macro differences between this one and D. venosa are that this one appears to be a mature specimen but has not become flat and highly veined, and the margin of this specimen is irregular to serrated rather than smooth. Matches pretty well with P. arvenensis. Tough to get this sort of thing home in one piece while lugging a around a bagful of morels.
