Daniel,

Thanks for interacting with me on this observation. I’m relatively new and starting to understand all the details necessary to make correct id’s. Like you said the photos do give the fungus a stronger yellow appearance than I noticed in the field. I think this is due to the translucence of the fruiting body. When I first spotted them the color was not that striking but I think there is definitely a hint of yellow in the fruiting bodies. I will be better about stating any differences between photos and field observations as well as attempting to have the photos accurately portray the color of the fungi in the field. Thanks again.

does treat Peziza micropus as a species. It is included with other Pezizas, and synonymy with Peziza varia and P. repanda is suggested.

Peziza micropus was first suggested from Brittain on elm. American elm is not commonly found in Britain.

Regarding color: your photos show yellow shades. If the fungus was more a “tan color” than yellowish, you need to include that information in your comments about the fungus. In other words, if the photos are not representative of the fungus you saw, you should include that information first, so that all on MO can reference them.

Maybe Peziza micropus

This was one fruiting body of several on a downed, severely decade log. The fruiting bodies were not clustered and the struck me as more of a tan color than any kind of light yellow. Peziza micropus is a European species common on beech and elm. There are several dead elm at this site but this log was unidentifiable.

In Arora,

P.r. described as “Fertile (upper or inner) surface pale brown to medium brown, tan, or in age somewhat darker, smooth to somewhat wrinkled or convoluted at the center.” Arora’s photos of P.r. show as mostly whitish undersurface, brown (sepia, red-brown, or darker) inner surface, which becomes nearly flattened or planar in age. This obs. is no where near flattened. It might be a Peziza, but a very light-colored one. Or it might be an Otidea which has not formed well.
