Habitat and Range
Peziza fimeti "also grows in dung, but is smaller (up to 2cm) and dull brown, seldom grows in clusters, and has smaller spores", (Arora). P. fimeti grows on dung and has smooth spores in the same size range, but differs in small disc-shaped fruitbodies and other characters, (Hansen, K.). Phillips(1) says that Peziza bovina is found in the Pacific Northwest: according to Dennis(1), it has "similar ascospores, 19-22 x 9(10) microns borne by small (under 1cm diameter) umbilicate-revolute umber-brown apothecia on cow dung".
