^ PsiLOPEZiA NUMMUiAKiA : orbicular, one-third of an inch broad, fiat, pur- 

 ple-brown growing on a white, tomentose stratum, which forms a narrow 



border; asci large, containing eight large, elliptic binucleati sporidia. The 



characters of this genus are precisely those of Fyroncma, which was founded 

 on the old confluent state of Peziza omphahdes. It has the habit of Corlicum 

 w^ith the hymenium of a Peziza, from which it is distinguished by the total 

 absence of any true margin. The name of Pyronema is evidently inapplica- 

 ble to the present species. 



3 Pateliaria cahpikea : This is not a goodPcziza, though it certainly has 

 asci and sporidia. The former are clavate, the latter subrymbiform. Ditiola, 

 to which Fries is inclined to refer it, has no asci. It appears to me evidently 

 congeneric with Pez. rhabarbarine, Berk.
