REPORT OF THE STATE BOTANIST IQI5 4I 
On dead branchlets of Cornus florida L. Yonkers, N. Y. 
H. D. House, May 8, 1915. Type in the herbarium of the New 
York State Museum. 
Sphaeropsis viburni-dentati Dearness & House, sp. nov. 
Pycnidia gregarious in the cortex, globose, 160-300 yp, raising 
the covering cuticle which is minutely pierced by the short 
black ostiola; conidia 'pale brown, oblong with rounded ends, 
I8x7 p to 22x 6% up, on basidia which are one-half to two-thirds 
of the length of the spores. 
On dead stems of Viburnum dentatum Linn. Albany, 
N. Y. Collected by H. D. House, May-June, 1915. Type in the 
herbarium of the New York State Museum. 
Differs from Sphaeropsis lantanae P. Brun., which 
has smaller dark-brown spores in erumpent, black perithecia, and 
from Sphaeropsis viburni Ell. & Dearness, which has 
larger, dark-brown, subpyriform spores and is phyllogenous. 
Stagonospora convolvuli Dearness & House, sp. nov. 
Spots reddish brown, irregular, .5 to 1 cm broad, deciduous, not 
bordered but faintly concentrically ridged on the upper side. 
Pycnidia mostly epiphyllous, black around the perforate mouth, 
80-125: in diameter, obscure or imperfect beneath. Sporules 
hyaline, fusoid, subacute at one end, rounded at the other, nucleate, 
faintly 2-3 septate, 15-18 x 3-4 wp. 
On living leaves of Convolvulus sepium L. Roadside 
north of Liverpool, Onondaga county. H. D. House, August 12, 
1915. Type in the herbarium of the New York State Museum. 
It was thought at first that this might be a variety of Septoria 
calystegiae West., but that has smaller spots and filiform con- 
idia 30-40 x 4-5 p. The difference between Septoria and Stagono- 
spora is mainly that of “ filiform” and “ fusoid” as applied to the 
shape of the conidia. The specimens here considered belong clearly 
to the later type and hence to the genus Stagonospora. © In 
Septoria calystegiae the pycnidia are mostly hypophyllous. 
Vermicularia polygoni-virginici Schw. 
On dead stems of Polygonum muhlenbergii (Meisn.) 
S. Wats. Sylvan Beach, Oneida county. H. D. House, May 13, 
IQI5.
