whitish, pruinose, fleshy, brittle, substipitate or sessile. Stipe 

 very short and thick. Hymenium brownish hypothecium and 

 exciple of about the same color. Cells of the exciple and the 

 hypothecium are elongated cylindrical cells of septate hyphae. 

 Paraphyses enlarged at the ends, slightly adherent, rather nu- 

 merous, quite brown at ends because of brownish granules. 

 Asci cylindrical. Spores uniseriate, oval, smooth, 20-23 mic. 

 long and 10-12 mic. wide. 



Apothecia are about twice as thick as those of Peziza re- 

 panda Wahl. Growing on earth in woods.

Apothecia solitary, about 10 cm. broad, sessile, funnel- 

 shaped, becoming quite expanded, interior umber brown and 

 having large anastomosing veins, exterior nearly the same color 

 when damp but, when somewhat dry, becoming whitish, very 

 slightly pruinose or having minute fasciculate hairs, edge very 

 tough becoming very dark, entire. Hymenium pale brownish, hy- 

 pothecium of the same color, central part of the cup with less col- 

 oring and composed of a network of hyphae, outer cells some- 

 what dark. Paraphyses filiform, brownish, slightly clavate. 

 Asci cylindrical, broader than those of P. repanda and P. re- 

 ticulata. Spores smooth, hyaline, broadly elliptic, 20-24 mic. 

 long and 19-12 mic. wide. 



Growing on the ground in the woods.

Subgenus II. Plicaria. 



Apothecia often in groups or caespitose, sessile, at first 

 spherical and closed becoming plane and more or less irregular in 

 shape and often torn, fleshy. Paraphyses branched at the base, 

 more or less enlarged upward, hyaline or colored. Asci cylindri- 

 cal, ends quite blunt. Spores elliptical or oval, smooth or rough, 

 simple, with or without oil globules, hyaline.
