Moreover, we have detected no septum in the sporidia. The 
radiating asci in Microthy yrium is an arrangement not met with in 
the Spherella. Hence it is evidently a too hasty assumption that 
the Spheria Buzi of Demuanes is Microthyrium. In fact, if the 
cuticle be ss from the leaf and submitted to the microscope 
this will be prov

This we regarded hitherto as a variety of Spheria Buzxi, but 
further ohaativatidh disproves this. e perithecia are more pro- 
minent, usually two to four a r, of a darker colour, nearly 
black, and the time Rad ice s long, and probably would be 
uniseptate when fully matured.

is onritted, as well as all moriiteh to his description. An original
