Pezizomycetes
Pezizomycetes are a class of fungi within the division Ascomycota.
Pezizomycetes are apothecial fungi, meaning that their spore-producing/releasing bodies are typically disk-like, bearing on their upper surfaces a layer of cylindrical spore-producing cells called asci, from which the spores are forcibly discharged.
Important groups include: cup fungi, morels, Elfin saddles, and truffles.
