Davis—Parasitic Fungi in Wisconsin — 11. 105 
Ascochyta saniculae n. 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/* 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 skepherdiae 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/*. Collected on ShepJierdia canadensis at 
two stations near Ellison Bay and at Detroit Harbor. I have not 
seen Septoria argyraeae Sacc. which I suspect is not very differ¬ 
ent. 
Ramularxa 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 3-4/*; coni- 
dia apical, hyaline, cylindrical, obtuse at both ends, distal %- 
% more or less strongly curved, becoming 1-4 septate, 40-80 x 4 
-5/*. 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 EU. & Barth. On Solidago undigulata. 
Athelstane. The specimen referred here bears conidia usque 
118 x 3-4/* on short conidiophores. The affected leaf areas are
