Septocylindrium aromaticum Sacc.*^ 



Examination of the type of C >■ 1 i n d r o s p o r i u m A c o r i 

 Peck*" collected at Sandlake, on A c o r u s Calamus L., shows 

 that the tufts are superficial but on such inconspicuous hyphae that 

 it belongs in SeptocyHndrium, and differs in no essential feature from 

 the description of S . aromaticum by Saccardo. Von 

 HohneF" states that Saccardo's species is a true Ramularia and 

 transfers it to Ramularia a r o m a t i c a (Sacc.) Von Hohnel.
