g4 NATURAL HISTORY BULLETIN 



operculate, 8-spored; spores elliptical, 15 to 17 to 10/x, granular 

 within; paraphyses stout, thickened at their apices, 5 to 7/x in 

 diameter. 



On naked soil in woods, also grown in the laboratory on same 

 material. 



Two plants were grown in the laboratory from the soil on 

 which the plants were collected in the field. The hymenium is 

 nearly plane but surrounded with a delicate white fringe. The 

 asci are often found to be only 4 or 6-spored.

On the ground in woods, common. 



The plants are at first small and almost entirely globose be- 

 coming expanded and hemispherical with age. The species is 

 easily known by the white hymenium and external covering of 

 brown hairs, the plants being about the size of an acorn-cup.

Peziza albo-spadicea Grv., Fl. Edin. 420. 1824. 



Plants sessile, gregarious, at first subglobose becoming ex- 

 panded and often nearly plane, about 5 to 8 mm., externally 

 clothed with rather soft brown hairs; hymenium white or whit- 

 ish; asci cylindrical, 8-spored; spores elliptical, smooth, about 

 20 by 10/*; paraphyses filiform, slender. 



On naked soil in shaded places among weeds, Iowa City. 



The specimens referred to this species have been collected 

 often but never in large numbers. They resemble somewhat 

 the preceding but are much smaller and the cups which are at 

 first hemispherical become nearly plane with the margin often 

 slightly split, The hairs are softer and not so prominent as in 

 L. hemispherica.
