it is herein described as shown in our local fungi. Professor C. 
H. Kauffman, of the University of Michigan, has kindly compared 
specimen number 749 of the exsicatti of Ellis’ N. A. F. with the 
above description and says that it agrees well with it. 
MELANCONIALES. 
Cylindrosporium Capsellae E. & E. 
On living leaves of Lepidium Virginicum, six miles west of Bloom- 
ington, July 25, 1920. 3861. 
The measurements of the spores on this new host agree well with 
those in the description, except that they are only 12 to 30 by 
2 to 2% microns, while in Ellis and Everhart’s original descrip- 
tion they are given as 35 to 45 by 3. We have two specimens 
collected on Capsella Bursa-pastoris. The spores in these are 
slightly longer, measuring 15 to 37 by 2 to 2%. They are vari- 
ously curved and are 1 or 3-septate, not uniform in thickness and 
occasionally pointed at one end. Though differing somewhat from 
the original description, it seems proper to refer this specimen to 
C. Capsellae E. & E. In addition to the spore difference noted 
above, the acervuli are hypophyllous as well as epiphyllous. 
Marsonia Thomasiana Sace. 
On living leaves of Evonymus atropurpureus, Showers’ Farm, 
August 26, 1920. 3811. 
Spots 1 to 6 mm. broad, usually 1 to 3 mm., amphigenous, sub- 
circular or angular, with reddish margin; acervuli amphigenous, 
erumpent through the cuticle, 25 to 50 microns and later often 
extending so as to cover most of the spot and leaving a white, 
flaky appearance due to the adbundance of spores drying in masses; 
spores 17 to 30 by 8 to 12 microns, mostly about 20 to 25 by 10, 
pyriform, usually constricted at the septum; the upper cell twice 
the width of the lower one, subspherical and occasionally not ex- 
actly above it but tilted slightly to one side by the lower cell being 
bent; conidiophore very short cylindric, about 4 to 7 by 4 to 5 
microns. 
HYPHOMYCETES. 
Cercospora avicularis Wint. 
Common on living leaves of Polygonum species throughout Monroe 
County. 2805. Collected on the Showers’ Farm, August 20, 1920. 
Spots scattered, amphigenous, 1 to 6 mm., brown in dried speci- 
mens, bounded by a narrow elevated reddish-brown line, yellowish 
outside this line; tufts of conidiophores chiefly epiphyllous; conidio- 
phores short, about 25 by 4 microns, colored at the base; conidia 
pale yellow (almost hyaline), 3 to 7-septate, curved or straight, 
40 to 90 by 3 to 4 microns. Distinguished from C. polygonacea 
E. & E. by its short conidiophores. 
Cercospora depazeoides (Desm.) Sacc. 
On living leaves of Sambucus Canadensis, Showers’ Farm, August, 
1920. 3810. Our specimen agrees with the European type rather 
than with C. sambucina E. & K. collected in New York and Kansas. 
The spots agree with those described for C. depazeoides except
