Apothecia scattered or gregarious, sessile, expanding, and at 

 maturity becoming scutellate to discoid, not usually exceeding 

 1-2 cm. in diameter; hymenium at first concave, becoming plane, 

 finally a little convex, often umbilicate, brownish-black with a 

 slight tinge of green; asci cylindric above, tapering rather 

 abruptly below into a stem-like base, reaching a length of 

 300-350 /x and a diameter of 15-17 ^u, 8-spored; spores 1-seriate 

 or occasionally slightly crowded, parallel with the ascus or 

 oblique, at first smooth, becoming sculptured, very faintly 

 yellowish or olive, containing two conspicuous oil-drops or more 

 rarely one, 10-11 X 20-22 m; spore-sculpturing taking the form 

 of rather conspicuous warts about 2 ju in diameter; paraphyses 

 rather strongly enlarged above, reaching a diameter of 7-8 /x 

 at their apices, yellowish-brown. 



On the ground in damp places. 



Type locality: Europe. 



Distribution: New York to Iowa; also in Europe.

3. Peziza spissa Berk. Grevillea 3: 152. 1875. 



Humaria spissa Sacc. Syll. Fung. 8: 141. 1889. 



Apothecia gregarious, at first shallow cup-shaped, becoming 

 discoid, attached to the substratum by a short stem-like base 

 which is obscured at maturity, reaching a diameter of 1-2 cm.; 

 hymenium concave, becoming convex, dark-brown; asci cylindric 

 or subcylindric above, tapering below into a stem-like base, 

 becoming spirally twisted when young, reaching a length of 

 260-275 Ai and a diameter of 23-24 fx; spores 1-seriate, obliquely 

 or irregularly disposed, ellipsoid, usually containing two large 

 oil-drops and often several smaller ones, granular within and 

 slightly yellowish, smooth, then becoming very minutely sculp-
