Alysidium, Kze. 



Note. This genus was founded on Alysidium fulvum, Kze. of which the 

 North American references are given below. As limited by some authors it 

 includes certain species referred to Oidium, Oospora, etc. Since all the 

 fungi of this group are either known or suspected to be imperfect forms of 

 higher fungi it seems to us unnecessary to attempt to settle the question as to 

 what is the oldest name of the genus to which they might be referred and we 

 have preferred to retain most of them in Oospora, the genus under which 

 several of our species were first described and under which they are to be 

 found in most recent works.
