CRYPTOGAMIA. 



There are two specimens of this, one of which is depresso-globose, 

 produced at base into a short rugged stem nearly as long as the head, 

 the whole three-quarters of an inch high ; the other sessile, or with a 

 mere rudiment of a stem, and deformed, as if by the partial confluence 

 of two or three heads, thus somewhat resembling a small undulate 

 form of H. concentricum. The species is closely allied to H. poly- 

 morpJium, but the sporidia are shorter and thicker. It resembles E. 

 obovata, Berk., and S. poculiformis, Mont., but is distinguished from 

 both by its prominent ostiola, and rough coarse stem. 



Fries (in Nov. Symb. Myc. p. 114) expresses the opinion that this 

 species is his H. globomm.
