Summary:
Features include a cup-shaped or expanded fruitbody with the upper surface varying from ochraceous brown to pale brown, whitish scurfy underside, absent stem, growth on the ground in woods or on lawns, and microscopic characters including finely warted spores. There is considerable variation in the color of the upper surface, and the name Peziza howsei Boud. refers to a violaceous form of Peziza emileia according to Dennis(1), but is maintained separately by Hansen, L.(1). The online Species Fungorum, accessed January 4, 2014 gave the current name as Peziza howsei Roze & Boud. with Peziza emileia Cooke as a synonym.

Microscopic:
spores 17-22 x 8-11 microns, elliptic, finely warted, with 2 droplets; asci about 250 x 12 microns; paraphyses slender, straight, slightly clavate, colorless or containing violaceous granules, (Dennis), spores 16-18 x 8 microns, elliptic, becoming sculptured with very minute warts or papillae, colorless, uniseriate; asci reaching a length of 200 microns and a width of 12-15 microns, cylindric or subcylindric; paraphyses slender, strongly enlarged in upper part, septate, (Seaver), spores (17)18-21(22) x 8-10(11) microns, finely verrucose [finely warted] with 2 droplets; paraphyses simple, colorless, (Hansen)

Notes:
Peziza howsei (as P. emileia) is found at least in OR, CA, CO, UT, (Larsen), WI, France, (Seaver), United Kingdom (Dennis), and Denmark, Norway, and Sweden, (Hansen). There are collections from BC at the Pacific Forestry Centre determined (as P. emileia) by J. Groves and by J. Ginns.
