branched, tortnons intrafoliar mycelium which is seldom filamen¬ 
tous but usually nodulose to moniliform. It is possible that this 
will prove to be a form of Cercospora convolvuli Tracy & Earle 
(Bull. Torrey Bot. Club 27:187). 
Cercospora tortipes n. sp. 
On indefinite leaf areas or entire leaves which finally become 
dead; fasciculi small, scattered, mostly hypophyllous; conidio- 
phores fuligenous, usually divaricate, tortuous and denticulate, 
sometimes septate, seldom branched, 30-60 x 3/*,; conidia hyaline, 
obclavate-cylindrical, straight or somewhat curved, 50-130 x 3^. 
On leaves of Veronica scutellata. Bruce, Wisconsin, September 
4, 1918. 
Cercospora tabacina Ell. & Evht. 
On Rudbeckia laciniata. Cornell. The translation of “ ab¬ 
ruptly bent” by “abrupte incurva” in the Sylloge Fungorum is 
somewhat misleading. Much longer conidia occur than the de¬ 
scription indicates, one having a length of 250 p having been meas¬ 
ured. The leaf tissue of an old spot becomes filled with monili¬ 
form mycelium, and what appear to be immature epiphyllous peri- 
thecia occur. A collection on Prenanthes alba from Mosinee I 
have also referred to this species. Collected also at Tomahawk on 
this host. The conidiophores are not always bent but are often 
undulate instead. 
[A collection has since been made on Rudbeckia hirta at Cary- 
ville in which the development is less vigorous the conidiophores 
being largely scattered and nearly straight, 70-100 x4/u, and the 
conidia 25-45 x 3-4y, indistinctly septate or continuous.] 
There was collected in small quantity on Trifolium repens at 
Madison in the spring of 1916 and of 1917 a rust that I have re¬ 
ferred to TJromyces flectens Lagh. 
Puccinia montanensis Ell. & Evht. 
Telia on Elymus canadensis. Hancock. Determined by Ar¬ 
thur. 
Kern has segregated Puccinia canaliculata (Schw.) Lagh. from 
P. cyperi Arth. (Mycologia 11:136 et seq.) Cyperus strigosus 
and C. Houghtonii are hosts of P. canaliculata in Wisconsin. To 
this species Kern refers the Aecidium on Xanthium also. 
Puccinia cicutae Lasch. 
Telia on Cicuta maculata. Bruce and Cornell.
