There can scarcely be a more common plant than this species
of Ascoholus, and it is therefore at the command of anyone
who wishes to satisfy himself by microscopical investigation
of the nature of the genus. Except in the striking peculiarity
of the fructification, the Ascoboli do not differ from the Pezizce,
and, except by one somewhat versed in mycology, would be at
once pronounced Peziza;. P e r s o o n established the genus in
his Observationes Mycologica;, published in 1796. In his My-
cologia Europaea, seven species are enumerated ; eleven in the
Systema Mycologicum of F r i e s .
