var. osmophila n. var. 
Spots like those of the type; sporules uniseptate 12-21 x 3-5/a. 
On Agastache Foeniculum. Danbury. 
var. lycopina n. var. 
# 
Spots suborbicular to angular, blackish brown above, lighter 
below, immarginate, 3-10 mm. in diameter; pycnidia few, scat¬ 
tered, innate, ostiole directed toward the upper surface of the 
leaf, very inconspicuous; sporules hyaline or smoky tinged, 
cylindrical with rounded ends, uniseptate, 16-24 x 7-8/*. On 
Lycopus uniflorus. Shiocton, Wisconsin, August. 
Collections on Sanicula marilandica having uniseptate 
sporules 20-30 x 4-6/a were described in Trans. Wis. Acad. 
18 1 :105, under the name Ascochyta saniculae n. sp. The af¬ 
fected leaf areas are usually larger and less definite in the form 
on this host. This has also been collected on Zizia aurea at 
Melvina. On this host definite orbicular to elliptical olivaceous 
spots y 2 -l cm. long occur. Both of these probably should be 
referred to Ascochyta thaspii Ell. & Evht. the sporules of which 
were described as being 25-30 x 6-8/*. In the Wisconsin speci¬ 
mens on Zizia the sporules are 18-25 x 4—6/a and are perhaps 
immature. 
Next comes a form that may be designated 
Ascochyta compositarum n. sp. Forming large indefinite 
brown areas and also smaller more definite spots about 
1 cm. in diameter; pycnidia as in the previously mentioned 
forms; sporules hyaline, uniseptate, 15-22 x 4-6/a. On Eupa- 
torium urticaefolium, Helianthus strumosus and Aster Drum- 
mondii. Of one specimen on the former host it was noted 
“sporules not well developed, 12-16 x 3-4/a .’ 9

It is probable that this species occurs upon other Composites 
and that A. thaspii E. & E. will be found on other TJmbelliferae. 
Indeed I have seen the latter on Cicuta maculata but did not 
secure enough, for a specimen.
