 EXSICCATI: Ellis & Ev. Fungi Columb. 1903; Kell. & Swingle, Kans. 



Fungi 2; Sydow, Ured. Jf97. 



A characteristic species of wide range. It doubtless has its telial stage 

 on some host other than a grass or sedge. Its pycnia are subcuticular. 



28. Accidiuin sp. 

 On SAXIFRAGACEAE : 



Mitella ntida L., Newfoundland. 



Only the one collection known from Shoal Point, Bay of Islands, New- 

 foundland. No doubt a distinct species. 



29. Aecidium Puniassiae (Schl.) Grav. Duby Bot. Gall. 2:904. 1830. 

 Caeoma Parnassiac Schl. Fl. Berol. 2:113. 1824. 



On PARNASSIACEAE : 



Parnassia palustria L., Alaska. 

 TYPE LOCALITY: Berlin, Germany, on Parnassia paliistris. 

 DISTRIBUTION: In America, known only from Alaska. 



In Europe this is considered the aecial stage of Pitccinia nliginos-i 

 Juel, which it may also prove to be in America. 



30. Aecidium sp. 



Aecidium Cassiac E. & K. Trans. Kans. Acad. 10:91. 1SS7. (nomen uu- 



dem) not Aec. Cassiae Bres. 

 On CAESALPINACEAE : 



Cassia Clianiaecrista L., Kansas, Nebraska. 

 TYPE LOCALITY: Manhattan, Kansas, on Cassia Chamaecrista. 

 DISTRIBUTION: Central Mississippi valley. 



This Aecidium dift'ers decidedly from Aec. Cassiae Bres. in having 

 considerably smaller spores than the African species, and is without ques- 

 tion distinct from it. Ellis & Kellerman's name was never established, 

 as far as the writer can determine and not now an available one. This 

 being the case, this Aecidium is still uiuiamed.
