Re : Asco from California, USA
Hello,
that's an interesting discomycete. That stipe reminds me of Tarzetta, but if the spores really are without guttules, then my best guess is a Geopyxis. If you can check the ascus base, Tarzetta has simple septate base, Geopyxis has forked (pleurorhynchous) base.

Re : Asco from California, USA
Tarzetta species possess large guttules in their spores.
Consider also the genus Jafnea (especially J. semitosta) because your micrographs show immature ascospores, but the spore shape agrees.
