a variety of Peridermium abietinum, (A. & S.) by

652. Doassansia intermedia, Setchell. 
On 8agittaria variabilis , Engelm. Vilas county. 
Through the courtesy of Dr. Setchell, I have been 
able to examine authentic material of this species, 
the description of which appeared in the Botanical 
Gazette , 19, 185-86, 1894. Doassansia affinis, 
Ell. & Dearn., which I consider a synonym, was 
published in the Bulletin of the Torrey Botanical 
Club , 22, 364, 1895, consequently the name used 
has prioritv and it is not invalidated by Doassansia 
intermedia , Morot (on Alisma ), Journal Botanr 
ique , 1895. Since this was written Prof. G. P. 
Clinton has announced the same conclusion. Jour¬ 
nal of Mycology , 8 , 63, 129. This appears to have 
a northern range: Shelburn, K. EL, Farlow; 
London, Canada, Dearness; northern Wisconsin;
