There are too many missing information to help you more.
1/ it is probably a Peziza sp. although you did not mention if the iodine blue reaction at ascus tip was checked.
2/ spores are smooth or not, guttulate or not (I guess it is), width
Spores have to be examined outside asci in cotton blue
3/ paraphysis, shape, tip, gel cap, width
4/ flesh : thickness, textura, layers
In Europe, with such substrate, Peziza vesiculosa is frequent. it is a big ochraceous yellow species (up 10 cm, 4 inches?), vesicle shape, but with longer smooth spores. I know several european Peziza keys, maybe not totally suitable for America, but have not in mind such work for american species.
Let us wait for Dick Korf's point of view.

Re:Peziza ?
Chers Tous,
Il est possible qu'il s'agisse de P. vesiculosa, elle en tout à fait le faciès Ce qu'il est intéressant, de savoir s'agissant de cette espère et qu'il arrive que les asques ne réagissent pas à l'iode. J'ai eu le cas sur deux récoltes dont l'une faite sur de la paille. Cette particularité, qui peut être déconcertante, est signalée par GRELET, dans "Les Discomycètes de France" rééd.1978 p. 62.
