What is this? Under Quercus agrifolia in Oakland. Size approx 2 - 3 cm diameter.Spores smooth, inamyloid, 18 × 10 micrometers. Asci inamyloid and with a rounded apex. Micrographs in Meltzer's.
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.

Consider also the genus Jafnea (especially J. semitosta) because your micrographs show immature ascospores, but the spore shape agrees.
