Alysidium Kunze. Myk. Heft. 1 : 11, 1817 must be used 

 instead of Oospora Wallr. Fl. Crypt. Ger. 2 : 182, 1833. 

 the name adopted by Saccardo. Alysidium was founded 

 for A. fulvum Kunze. = Oospara fulva Sacc. & Vogl. 1. c. 

 Moreover, Bonorden, Handb. 35, 1851, took up Alysidium 

 and described several species, one a Torula, but the rest 

 placed in Oospora by Saccardo. Even those who would 

 oppose a year limit of fifty years to the rule of priority, 

 must restore the name Alysidium. The saprophytic spe- 

 cies were generally included with the parasitic ones in 

 Oidium until 1886, and neither Oospora nor Alysidium 

 were in general use. But the latter having been adopted 

 in 1851 by Bonorden cannot be called obsolete. Acros- 

 permum.'^ees 1816 was founded on Oidium monilioides 

 and was applied to this genus by Persoon in 1822.
