Davis—Notes on Parasitic Fungi in Wisconsin- — IV. 673 
as septate sporules are now and then found, that septation comes 
with maturity. A collection on Smilax rotundifolia from Lynx- 
ville bears ovoid or ovate more deeply tinted smaller sporules 
and is perhaps Ascochyta confusa Ell. & Evht. [See Dearness. 
Mycologia 9: 359-60.] 
Septoria candbina West, of the provisional list should be Sep- 
toria cannabis (Lasch.) Sacc. In a specimen from Lynxville 
the sporules are 25-45 (mostly 30-36) x2-2 y 2 fi. 
The host given as Rumex altissimus in the provisional list is 
probably R. mexicanus. 
R. E. Stone finds Septoria ribis Desm. to be genetically con¬ 
nected with Mycosphaerella grossulariae (Fr.) Auersw. (Phyto¬ 
pathology 6:109). 
The fungus recorded in the provisional list under the name 
Cylindrosporium. ribis Davis is evidently conspecific with 
Brenekle ? s Fungi Dakotenses 320 which was determined by Sac- 
cardo as Septoria sibirica Thuem. Saceardo gives a description 
in Annates Mycologici 13:122. This seems quite different from 
European material distributed under this name. 
For the fungus described by Trelease under the name 
Ascochyta salicifoliae and referred to Septoria by Berlese & 
Voglino and by Ellis & Everhart I am using the name Cylin¬ 
drosporium salicifoliae (Trel.) as better expressing the acer- 
vular character of the spore body as I find it. 
Dr. E. A. Burt of the Missouri Botanical Garden has kindly 
examined the type of Gloeosporium (Marsonia) meliloti Trel. 
and sent mounted sections thereof. It proves to be the 
Ascochyta caulicola of Laubert and A. lethalis Ell. & Barth. R. 
E. Stone has connected it with an ascigerous form to which he 
gave the name Mycosphaerella lethalis Stone. In the descrip¬ 
tion Trelease designated the spore bodies ‘ ‘ Perithecia ’ ’ which 
was changed to “acervuli” in the Sylloge Fungorum doubtless 
to conform to the character of the genus to which it was re¬ 
ferred. The word pycnidium was not then in use. 
Examination of type material of Gloeosporium populinum 
Pk. received from Dr. H. D. House shows it to be the same as 
43—s. A. L.
