Pseudopeziza paulula. Mass. 



Scattered or usually gregarious, erumpent, miuute, {-I mm. 

 across, glabrous, closed at first, then expanding and concave ; 

 disc pale, margin whitish, entire, externally blackish with 

 an olive tinge, surrounded at the base, especially when 

 young, by a narrow white zone of hyphae which spring 

 from the basal cortical cells ; cortex parenchymatous, cells 

 irregularly polygonal, 710 /x diameter, arranged in a 

 parallel series, and pale at the margin ; asci broadly 

 elliptical, usually rather broadest near the base, apex 

 rather narrowed, sessile or very nearly so, 8-spored ; spores 

 irregularly 2-seriale, hyaline, continuous, narrowly elliptic- 

 oblong, ends rather blunt, often 2-guttulate, 1214 X 4-5 p;

Pseudopeziza graminis. Mass. 



Erumpent, sessile, gregarious or scattered, emerging 

 through a slit in the epidermis of the host-plant and

 glabrous, often slightly wrinkled, about 1 mm. diameter; 

 cortex parenchymatous, cells brownish below, polygonal, 

 somewhat elongated from base to margin, becoming narrower 

 upwards, and running out into distinct, pale, obtuse hyphae, 

 40-65 X 4-5 p., to form the pilose margin ; asci cylindric- 

 clavate, apex narrowed, base stout, 8-spored ; spores irregu- 

 larly 2-seriate, narrowly elliptic-oblong or slightly clavate, 

 hyaline, continuous, 12-16 x 3-3 5 p.; paraphyses slender,
