Davis—Notes on Parasitic Fungi in Wisconsin — V. 703 
or geniculate, becoming denticulate and developing one or two 
septa. 
Alternaria soncki Davis. Parasitic on leaves of Sonchus asper. 
Madison. The description was published by John A. Elliott 
in the Botanical Gazette, 62: 416 (1916). 
TJromyces murrillii Ricker. The aecial stage, Aecidium hous- 
toniatum Schw., has been collected on Houstonia longifolia at 
Solon Springs and Millston but the further stages on Sisyrin - 
chium have not yet been detected in Wisconsin. This is TJromy¬ 
ces houstoniatus J. L. Sheldon, a name that violates the rule that 
I am following. 
TJromyces- striatus Sehroet. Uredinia on Medicago sativa 
(cult.) Weirgor. (F. R. Jones). 
Puccinia eriophori Thuem. Following field observations by 
Dr. House it has been shown by Dr. Arthur by means of in¬ 
oculation that the rust on Eriophorum is distinct from that on 
species of Scirpus and known as Puccinia angustata Pk. and 
that it developes aeeia on Senecio. Aecia on Senecio aureus 
have been collected in widely separated localities in Wisconsin 
and Dr. Arthur reports a collection of the rust on Eriophorum 
virginicum at Elm Grove by Dr. C. L. Shear. 
Cronartium ribicola Fisch. de Waldh.. The dreaded white 
pine blister rust has been found on Pinus Strobus in Polk 
County. Specimens of the aecial stage were collected by Moody, 
Sanders & Pierce in May, 1916, and Professor J. G. Sanders 
kindly furnished specimens of uredinia on Ribes cynosbati col¬ 
lected in June. 
Aecidium uvulariae Schw. On Oakesia sessilifolia. Melvina 
and Hixton. I suspect that this is not distinct from Aecidium 
majanthae Schum. and that it is connected with Puccinia ses- 
silis Schneid. 
In the 3rd supplementary list (Trans. Wis. Acad. 14:92) 
reference was made to the occurrence of a Doassansia on Sagit- 
taria heterophylla that was referred to Doassansia sagittariae 
(West.) Fisch as forma conftuens with the statement that it ap¬ 
peared to be physiologically distinct which opinion has been 
supported by subsequent observation. Morphologically, however,
