683. Ascochyta clematibina Thum. 
On Clematis Virginiana L. Kenosha county. I have 
used the above name because there is in the Ellis 
herbarium a specimen of what appears to be the 
same fungus which is so labeled. I append my 
notes on the Wisconsin specimens: Spots sub- 
orbicular to irregular, brown, becoming cinereous 
with a blackish brown border; pycnidia epiphy- 
llous, prominent, hemispherical to globose, amber 
colored to light brown or ochraceous, 100—125 
microns in diameter; sporules oblong, hyaline, 
continuous, 2—4 nucleate, 10—15 X 3 microns 
in germination becoming a third longer and twice 
as thick and 1—3 septate. Wrinkling of the 
cuticle sometimes gives the spots the appearance 
of bearing radiating whitish fibrils.
