Davis — Parasitic Fungi in Wisconsin — II. 105 



Ascochyta saniculae ii. sp. On indefinite, discolored, more 

 or less mottled areas which may include the entire leaf ; pycnidia 

 scattered, innate, globose to lenticular, thin walled, light reddish 

 brown with a round apical pore surrounded by a dark ring, 

 100-170/4 in diameter; sporules hyaline, cylindrical, usually 

 straight, 4-guttulate, 20-30 x 4-6^. On leaves of Sanicula 

 marilandica. Grant County, Wisconsin, September 19th, 1913. 

 The pycnidia are very inconspicuous. They are most readily 

 seen by transmitted light when they show as translucent points. 



Cylindrosporium shepherdiae Sacc. (Ann. Mycol. 11 :551. 

 1913). To this species, founded upon material collected at 

 Field, B. C. by Dearness, I am referring specimens from which 

 the following notes were made. The spots are circular, reddish 

 brown, concentrically rugose, 3-5 mm. in diameter. They have 

 a greenish border and are seated upon an indefinite yellowish 

 area. The epiphyllous pycnidia ( ?) are aggregated in the cen- 

 tral portion of the spot, are soon erumpent, and widely open, 

 the white mass of sporules within being visible under a hand 

 lens. The sporules are hyaline, oblong-cylindrical, obtuse, pluri- 

 septate, 18-40 x 3-4/x.. Collected on Shcplierdia canadensis at 

 two stations near Ellison Bay and at Detroit Harbor. I have not 

 seen Scptoria argyraeae Sacc. which I suspect is not very differ- 

 ent. 



Ramularia fraxinea n. sp. Spots none, the fungus appearing 

 as small snow white patches on the lower surface of the leaves; 

 conidiophores densely clustered on a more or less hemispherical 

 stroma, hyaline, sometimes bulbous at base, 10-20 x 3^1/i. ; coni- 

 dia apical, hyaline, cylindrical, obtuse at both ends, distal %- 

 % more or less strongly curved, becoming 1-4 septate, 40-80 x 4 

 -5/x.. On languishing leaves of Fraxinus pennsylvanica. Bridge- 

 port, Wisconsin, September 17, 1913. The gross appearance sug- 

 gests a light development of Microstroma and the shape of the 

 conidia a hockey stick. Perhaps this should be referred to 

 Fusarium. Since collected on Fraxinus pennsylvanica lanceo- 

 lata at Maiden Rock. 



Cercosporella nivea Ell. & Barth. On Solidago uniligulatax 

 Athelstane. The specimen referred here bears conidia usque 

 118 x 3-4|U, on short conidiophores. The affected leaf areas are
