Pezizella Fuckel, Symb. Myc. 299. 1869. 

 Myridium Clements, Gen. Fungi 174. 1909. 



Apothecia sessile, membranous, subgelatinous, bright-colored, 

 white, yellow, or red, typically smooth, subcorneous when dry; 

 asci cylindric to clavate, usually 8-spored; spores bacilliform, or 

 ellipsoid to subglobose; paraphyses filiform the apices often 

 clavate to subglobose. 



Type species, Peziza leucostigma Fries. 



The plants of this genus are usually minute but because of 

 their light or bright color they are more easily seen and conse- 

 quently often collected. The apothecia are typically thin and 

 membranous, the substance subcartilaginous and often trans- 

 lucent. The spores are minute and often difficult to diagnose. 

 A number of the species have paraphyses with subglobose or 

 pyriform apices.
