bodies much shorter than the asci, but nearly as broad. They are 

 often tilled with large, unequal, crowded nuclei, and appear more 

 like undeveloped asci than like ordinary paraphyses. The interior 

 surface of the stem is scurfy like the exterior. 



Peziza orbicularis. 



Plate 2, figs. 4-6. 



Receptacle 8 to 12 lines broad, sessile, appressed to the matrix, 

 nearly plane, orbicular or sometimes irregular, externally whitish 

 or subolivaeeous and slightly gelatinous when moist, the disk reddish- 

 brown or chestnut-colored ; asci, cylindrical ; spores uniseriate, ellip- 

 tical, .0009 to .0011 in. long, .00045 to .0005 in. broad ; paraphyses 

 lihform, thickened at the tips, brownish. 



Wet, much decayed wood. Brewerton and Guilderland. Sep- 

 tember and October. 



The spores usually contain one or two large nuclei. The contrast 

 between the dark color of the disk and the light color of the exter- 

 nal surface is quite noticeable. The flattened orbicular form of the 

 receptacle when growing on smooth surfaces suggests the specific 

 name. In the Thirty-second Report both this and the next s[)ecies 

 were referred to the genus Bulgaria inider the respective names 

 B. bicolor and B. deligata^ but upon further observation their affini- 

 ties a[)pear to me to bring them in the genus Peziza, subgenus Dis- 

 cina, in consequence of which I am obliged to change the names. 



Peziza leucobasis. 



Plate 2, figs. 1-3. 



Receptacles 1 to 3 lines broad, scattered or crowded, plane or con- 

 vex, sessile, scarcely margined, purplish-black when moist, black and 

 more or less angular when dr}^ surrounded at the base by dense 

 whitish filaments ; asci cylindrical, .01 to .012 in. long, .0009 to .001 

 broad ; spores uniseriate, elliptical, even, binucleate, subhy aline, .001 

 to .0013 in. long, .0006 to .0007 broad ; paraphyses numerous, fili- 

 form, septate, colored, slightly thickened above. 



Wet, decaying hemlock wood. Catskill mountains. July. 



The numerous white filaments that appear to bind the receptacles- 

 to the matrix, constitute a marked feature in this species and suggest 

 the specific name. 



Peziza longipila. 

 Plate 2, figs. 15-19. 



Receptacle small, .014 to .02 in. Inroad, narrowed below into a 

 short stem, densely clothed with long, rigid, erect, septate, tawny
