Two forms similar to the above were: 
M. caudatum'^ C. & E., Fungi Columb., 397. This was like the above 
but uniformly shorter. 
M. antennaeforme B. & C, Fungi. Columb., 2531. This species was in 
general form similar to those in the above group but the spores 
were uniformly more slender. 
Group 4 
Three other specimens were found with spores of the same form as 
the above group but the spores were much larger. These were: 
M. herculeum* E. &. M., N. Amer. Fungi, Ellis, 1263. 
M. commune^ Rabh., Fungi Europ., Rabh., 1360. 
M. saponariae Pk., N. Y. Fungi, Shear, 397; Fungi Sel. Ex., Roum., 
3868. 
Group 5 
Another group was formed of species with spores similar to those 
of Alternaria solani but generally wider and shorter and always more 
markedly muriform. The species in this group are not morphologically 
identical but merely similar. 
M. heteroschemon*"^ Faut., Fungi Sel. Ex., Roum., 6942. 
M. cucumerinuni^ E. &. E., N. Amer. Fungi, Ellis, 3396. 
M. nervii Cke., N. Amer. Fungi, Ellis, 964. 
M. sucaviae Trabut., Fungi Sel. Ex., Roum., 4098. 
M. convallariae Fr., Fungi Sel. Ex., Roum., 1897. 
M. hrassicae Berk., Fungi Sel. Ex., Roum., 6442. 
M. martindalei E. &. M., N. Amer. Fungi, Ellis, 1262; Fungi Europ., 
Rabh., 3282.

Alternaria malvae^ Roum., Fungi. Sel. Ex., Roum., 3393. 
A. hrassicae (Berk.) Sacc, Econ. Fungi, Sey. & Earle, 515.
