Peziza arvernensis (Boud.) Sacc. & Traverso                                       *Collections: California

This is the most common Peziza species that I see in our area (Northern California). It appears in Natural settings, as well as on woodchips. Another very similar species in California is Peziza repanda.

Amyloid asci tips -- I find them a beautiful sight...

Spores:  14-20 long, ornamented!!
