that they are 2 to 6 mm. This covers both the sizes described for 
C. depazeoides and for C. sambucina (4 to 6 and 2 to 4 respec- 
tively). The conidiophores agree also with the European form ex- 
cept that we have a minimum length of 50 microns. While the 
spores are for the most part 75 by 5 microns, they range from 50 
to 115 by 5 to 5%. It seems rather remarkable that our Indiana 
specimens should agree so well with the European form as com- 
pared with those from New York and Kansas situated as we are 
between the two States. In our judgment C. sambucina E. & K. 
is not sufficiently different from C. depazeoides to constitute a 
separate species. The “shot hole” effect of the fungus upon the 
leaves is very noticeable in our specimens. 
Cercospora granuliformis Ell. & Mart. 
On Viola cucullata (V. sororia), Kerr Creek, June 22, 1920. 3821. 
Varies from the description as follows: conidiophores 3 to 4 microns 
in thickness; conidia 20 to 62 long, straight or sometimes bent, 
cylindrical or enlarged near the base, 1 to 5-septate (mostly about 
3), hyaline and not brown. Our specimens have many things in 
common with C. Violae Sacc., C. murina Ell. & Kell. and C. granu- 
liformis Ell. & Holw. These common characters suggest a too 
close relationship of these species. 
Cercospora Nasturtii Pass. 
On leaves of Radicula Nasturtium-aquaticum at a spring one mile 
southeast of Bloomington, July 24, 1921. 3880. Large areas of 
this cress were killed by this fungus at this date. It appeared as 
follows: spots circular, 1 to 10 mm. (eventually spreading over 
and killing the entire leaf), pallid, with ochraceous border; conidio- 
phores amphigenous, fuscous, light colored at the tips; conidia 40 
to 112 by 4 to 6 microns, 3 to 7-septate (many are 4-septate), cyl- 
indrical to long tapering, some cells thicker than others, hyaline. 
Our specimens bear great resemblance to several species and va- 
rieties of Cercospora described on various Cruciferae, some of which 
seem too closely related. 
Cercospora murina Ell. & Kell. 
On Viola cucullata, I. U. Campus, July 13, 1916. 3700. 
Cercospora Rubi Sacce. 
On leaves of blackberry, Weimar Lake, October 21, 1920. 3851. 
Further study of specimen number 3655 reported in 1915 (Indiana 
Fungi IV) as C. septorioides E. & E. seems to assign it here. As 
stated there, C Rubi Sacc., C. rubicola Thuem. and C. septorioides 
E. & E. have many common characteristics, while our specimens 
differ somewhat from all of them as follows: spots amphigenous, 
one-third to one cm., orbicular, at times somewhat limited by veins, 
wood-brown to avellaneous, becoming paler with age, bounded by 
a purplish-fuscous border; conidiophores densely aggregated, short, 
15 to 30 by 38 to 4 microns, wavy above; spores 30 to 100 by 2 
to 4 microns, continuous to 7-septate, most of the larger ones 
slightly curved and 5 or 6-septate.
