SPILERONEMEI. 
Although perfectly satisfied that the majority of species included in 
this Order are nothing more than conditions of ascigerous fuugi, I have 
not hesitated to record such as have come under my own observation, 
with the names by which they are commonly recognized, because in 
any future and more satisfaetory arrangement these forms can be more 
aoe easily referred to under definite names, and moreover the species to 
beh they truly belong is, in many cases, only suspected.
