The Black-Bundle Disease of Corn 
191 
tion is published in English by Jensen, 1912 (25). Dop, 1906 (13), 
described a Cephalosporiumlike fungus upon the insect Aspidiotus 
perniciosus on the leaves of Cocos nucifera in the island of Mar¬ 
tinique. He named it Hyalopus yvonis. The description and spore 
measurements are in accord with C. acremonium. Bainier, 1907 (1) 
cultivated, described, and figured the fungus, as did Dale, 1914 (rr v 12 
P-. 5 6 )> . in working with soil fungi. She thinks also that the form deter¬ 
mined m her first paper (11, v. 10, p. 4.65) as Verticillium is really C. 
acremonium. Peyronel, 
1914 (59), found C. acre¬ 
monium now and then 
in the air on high moun¬ 
tains. Fawcett, 1915 
(15), reported a Cephalo- 
sporium sp. as the cause 
of “zoned” leaf spot of 
coffee. Zimmerman, 
1916 (50), reported the 
fungus as a parasite of 
scale insects on coffee but 
later gave it the name of 
C. lecanii. Ciferri in 
Italy, 1921 (8), reported 
Aspergillus varians grow¬ 
ing on kernels of maize 
that had developed on 
the extremities of the 
ears of plants growing 
in soil of low humidity. 
C. acremonium was fre¬ 
quently found by him as 
a parasite on the Asper¬ 
gillus. Manns and 
Adams, 1921 (29,30,31), 
made investigations upon 
fungi carried within the 
kernels of seed corn. 
They found that 39.54 FlG ‘ 4 '” After Fresenius b/, m. 3, pi. «. fig. 59-62).

was affected internally 
with a species of Cephalosporium which they determined as C. sacchari 
Butler and Khan. Butler and Khan (7) described C. sacchari as the cause 
of a wilt of sugar cane in India. The spores of this species are larger than 
those of C. acremonium and often become 1 to 3 septate before germinating. 
The authors found, upon examination of cultures kindly supplied by 
Manns and Adams, that the Manns and Adams Cephalosporium does 
not correspond to the species sacchari but to acremonium as described by 
Fresenius (77, p. 94-95), and therefore to the organism with which the 
authors are working. Branstetter, 1922 (4), followed Manns and Adams 
in the identification of the fungus on com as Cephalosporium sacchari. 
Relative to the fungi carried within the kernels, he says: 
The disease; survey shows that 1921 Missouri com was heavily infected with Fusarium 
moniliforme, Cephalosporium sacchari and Diplodia zeae in the order named.
