On willows in damp marshy ground. King's Cliffe, M. J. B, 

 We have little doubt that JE. perpusilla, Desm., is merely this 

 species. As no complete analysis has been given, we subjoin a 

 figure. There is certainly no peridium, and the genus is typi- 

 eaJly a compact O'idium. Dr. Greville figures the spores of jE. 

 Candida as globose ; but, beautiful as the figures of the Scottish 

 Cryptogamic Flora are, the more minute details arc often in- 

 correct. Spores -OOO^-'OOOS inch long.

824. Pilacre Petersii, Berk. & Curt. Stipite breviore can- 

 dido ; capitulo magno, floccis subrectis. 



On hornbeam. Hainault Forest, C. E. B. 



Stem 2 lines high, white; head 1-2 lines or more across; 

 threads anastomosing, far less flexuous than in P. faginea. 

 Spores snufi'-coloured, about '0002 inch across. When fresh, 

 it has a smell like that of some Hypericum. 



This species was originally found in Alabama by Mr. T. M. 

 Peters, and is No. 3811 of Mr. Curtis's Collection. It difi'ers 

 essentially in its white stem and large head. The threads per- 

 haps vary in character. The spores in both are nearly the 

 same. In habit the species resembles a little Nyctalis.

C. Hookeri, Kl., is probably referable to this species.
