2C4 ARTHUR-BISBY— TRANSLATION OF SCHWEINITZ'S 



Represented only by a mounted specimen, consisting of three 

 galls, each about 1.5 cm. broad, one of which bears numerous pro- 

 jecting telia, 5 mm. long, the other two much eaten by insects. The 

 fungus is one of the best known American rusts, now generally 

 listed under the name first given by Schweinitz. Why Link changed 

 the name, having no information except that supplied in Schweinitz's 

 Carolina list, and not having seen a specimen, is not evident. 

 Schweinitz accepts Link's substitute name, but places the species 

 under the genus Podisoma for reasons which he states. 



Note. — The above account includes all numbers pertaining to 

 rusts in Schweinitz's " Synopsis Fungorum in America Boreali." 

 It also includes all numbers possibly relating to rusts, given under 

 ^cidium, Uredo, Puccinia and Gymnosporangium in his " Synop- 

 sis Fungorum Carolinas Superioris " except two. 



No. "460. [Uredo] confltiens /?., rare on softer leaves, e. g. 

 Veratrum album," is represented by no specimen or original packet 

 at Philadelphia, and the identity of the collection must be left unde- 

 cided. No rust is known that would answer the requirement. 



No. "475. [Uredo] Betcc, a and ^, here and there on leaves of 

 the garden beet and on Ipomcea pandurance/' is represented by no 

 specimen or original packet. The most probable suggestion points 

 to species of the Phycomycetous genus Albugo to account for this 

 number.
