Usually non-septate, but about 10-20 % 1-septate, generally 
slightly constricted at the septum. 
Very rarely bi-guttulate.

septate (20 measurements). 
Form F. 
Issue in coils through ostiolum. Hyaline. 
Ovate to cylindrical with rounded ends, occasionally slightly 
curved. 
Usually non-septate, but 5 % of the spores from a tomato 
agar culture were 1-septate, and on Dox’s medium between 
5 % and 10 % were I-septate. Septate spores scarcely, if at 
21 constricted at the septum. In this form a spore mass 
which had been extruded some time from a pycnidium 
showed up to 50 % of the spores septate. 
About 40 % of the spores were bi-guttulate.

Ovate to cylindrical with rounded ends, occasionally slightly

Usually non-septate, about 5-10 % 1-septate, scarcely, if at 
all, constricted at the septum. Spores from a spore mass on 
Dox’s medium were about 30 % 1-septate. 
Occasionally faintly bi-guttulate.

Sometimes malformed and assuming a tubular form a milli-

one ostiole. 
Issue in coils through ostiolum, hyaline. 
Cylindrical, rounded ends, some slightly curved, some ovate. 
Sizes varying considerably. 
About 40 % 1-septate, the remainder non-septate. Always 
constricted at the septum. On potato aeee up to 80% 
I-septate. 
Occasionally bi-guttulate.
