[Prom careful observation of the living plants, and of extensive 

 series in my herbarium, it appears to me that there are two interr 

 n:iediate series (species ?) between C. pysidata and Jtmbriata. 

 They may be thus distinguished: — 



C. PYxiDATA, Fr. Podetia continuously corticate, granulate 

 Forma simplex. Scyphi cup-shaped, short, simple* 

 F. staphylea, Apothecia on the margin of the scyphi podicillate, large. 

 F. syntheta. Scyphi simply or repetito-proliferous. 

 F. lophyra. Scyphi fohaceo-crisped on the margin and prolificant. 

 T^' pocillum. Thalline leaves broad and thick; podetia and diaphragm 



vemicose 



verrucose 



C. PiTYREA, Ach. Podetia pulverulento-grannloso-furfuraceous, ashy 

 ^'hite, smooth and decorticate in the upper part. 

 Forma simplex. Scyphi simple. 

 F. denticulata. Margins of scyphi denticulate. 

 F' syntheta. Scyphi simply or repetito-proliferoua.
