CANADIAN FUNGI. 



BY J. B. ELLIS <fe BENJAMIN M. EVEKHART. 



The Fungi here enumerated were received from Prof. John Macoun, 

 Botanist to the Geological aud ISTatural History Survey of Canada, and 

 and were mostly collected during the summer of 1834.. The collection, 

 though small and consisting mostly of species already known, comprises 

 some not heretofore recorded in this country. 



PuccmiA MESOMEGALA, B. & C— On CUntonia borealis. Lake Ellen, 

 Nipigon River, June. 



Ptjccinia congregata, E. & H.— On Mitella nuda, islands in Lake 

 Nipigon. 



PuccmiA ASTERis, Duby, var. PunpuRASCEisrs, C. & P.— On Aster 

 macTopliyllus, Lake Superior region. 



PuccimA ^^Tardosmii, E. & E.— Sori numerous, hypophyllous, pur- 

 plish brown, subconcentrically arranged in circular clusters about 4 mm. 

 in diameter, soon naked. Spores rather /ariable in shape, elliptical to 

 oblong and often more prominent on one side, scarcely constricted at the 

 septum, 25— 30 X 15— 20 z^-, often narrowed above, epispore smooth, thick- 

 ened at the apex with a distinct, subhyaline papilla, pedicels about as 

 long as the spores, fragile and easily deciduous. 



On leaves of JSfardosmius {Fetasites) palmatus^ Red Rock, Lake Supe- 

 rior, June. 



The mostly smaller spores with smooth epispore and the more 

 decided, clustered mode of growth would seem to sufficiently distinguish 

 this from P. Compositarum^ Schlect. 



Uromyces Orobi, Winter.— On Lathyrus ochroleucus, Long Portage, 

 iSTipigon river. 



Triphragmitjm clavellosum. Berk.— On Aralia nudicauUs, Burnt 

 Island, iS'ipigon river, July.
