A NEW GENUS OF DISCOMYCETES.* 
By M. C. Cooke. 
The Discomycetes are a large group of fungi, which form a 
portion of the order of Ascomycetes. The substance of which the 
fungus is composed is of a fleshy or waxy nature, very similar to 
the soft flesh of many of the Agarics, and never hard, corky, or 
brittle, as in most of the Splneriacei. It is true that some genera of 
the Sphaeriaeeous group, such as Cordyceps and Hypocrea , have a 
similar fleshy substance, or stroma, but in these we recognise 
another point of difference, in the asci being enclosed within 
definita perithecia, which are embedded in the stroma, whereas in 
the Discomycetes there are no perithecia, the hymenium being 
always continuous over the fructifying surface. The form of the
