4^32 SPH^RONEMEI. 



Sometimea scattered, commonly gregarious, often in lines beneath the 

 cuticle, erumpent. Numerous species have already been described of this 

 gpnus, which is doubtless but a condition of higher forms. The fruit differs 

 80 slightly in the species on different herbaceous stems, that we hesitate to 

 characterise them as distinct.

On dead twigs of plane. Batheaston. 



Perithecia one or two together, at first concealed, at length exposed, glo- 

 bose, with a rather prominent orifice. Spores small, at first hyaline, elliptic 

 or obovate, ard falling off in that state, at length oblong, brownish, and 

 uniseptate. — B. <{: Br.

 sured epidermis. Sporidia elongated, opaque, brown and uni-

On damp cotton. 



Forming dirty black spots on the matrix, but without any evident floccose 

 stratum ; perithecia globose, at length cracking above, black. Eemarkable 

 for its singular habitat and free mode of growth. — B. d: Br.
