Cup cyathiform, entire, stipitate; margin furnished

Dr. Cooke has shown that the hair-like processes in 

 the four exotic species, for the reception of which he formed 

 the subgenus, viz. Peziza sulci pes (Berk.), P. Hindsii 

 (Berk.), P. tricholoma (Mont.), and P. insititia (B. and 

 C.), are not true hairs, but squamules, composed of a 

 number of longitudinal cells lying parallel to each other, 

 the exterior ones gradually diminishing in length, so that 

 the base of each squamule is broader than the apex. 

 This structure is the same in the teeth of the well-known 

 Peziza inflexa (Bolt.), and although this species is much 

 smaller than the exotic species named above, it must be
