Davis—Notes on Parasitic Fungi in Wisconsin — V. 701 
seen but the small spots and proportionately broader sporules 
described have deterred me from referring these collections to 
that species. 
Stagonospora zonata n. sp. Spots orbicular, clay colored 
with concentric dark lines, y 2 - 2 cm. in diameter; pycni- 
dia few, epiphyllons-immersed, depressed-globose, honey color, 
ostiolate, 120-180/* in diameter; sporules oblong to cylindrical, 
hyaline, 4-guttulate becoming 3-septate, not constricted, 12-25 
x 3^-6/*. On living leaves of Asclepias syriaca. Indepen¬ 
dence, Wisconsin, July 29, 1916; Arcadia, Wisconsin, July 31st, 
1916. Perhaps this is a better developed state of Ascochyta 
asclepiadis Ell. & Evht. 
Septoria mitellae Ell. & Evht. On <( Mitella or Tiarella.” 
Merrimack. Name of collector not given. 
Septoria stachydis Rob. & Desm. On Stachys tenuifolia. Mel- 
vina. 
Septoria krigiae Dearn. & House. Spots definite, suborbicu- 
lar, reddish brown, paler in the center, 3-8 mm.; pycnidia epiph- 
yllous, scattered, black, prominent, 50-75/*; sporules hyaline, 
straight or sometimes curved, 18-27 x %-l/*. On leaves of 
Krigia amplexicaulis. Arcadia. 
Cytodiplospora elymina n. sp. Pycnidia in the loculi 
of Phyllachora , spherical to elliptical, 100-135/*; sporules 
oblong, hyaline, often 4-guttulate, becoming uniseptate, 7-10 
x 23/2-3/*. On leaves of Elymus virginicus. Madison. This 
is doubtless a spermogonial state of the Phyllachora. 
Gloeosporium leptospermum Pk. On Pteris aquilina; accom¬ 
panying Phyllachora. Whitehall. The longest sporules attain 
30/* and the thickest 5/*. 
Colletotrichum circinans (Berk.) Yogi. Reported as occur¬ 
ring on onion bulbs in Wisconsin. (J. C. Walker) 
Marssonina rubiginosa Ell. & Evht. On Salix sp. indet. 
Madison. 
Monilia corni Reade. On petioles, midribs and peduncles of 
Cornus paniculata. Melvina. The fungus is apparently locally 
abundant on this species of host but I found conidia but once.
