Davis—Parasitic Fungi of Wisconsin. 749 
450. Septoria solidagixicola Pk. 
On Solidago arguta Ait. Racine. In this specimen 
the sporules are 24—36 X 1% microns. Septoria 
intermedia E. & E. on the same or a similar host 
is probably not distinct from this. 
480. Chrysomyxa cassandrae (Pk. & Cl.) Tranz. 
( Uredo cassandrae Pk. & Cl. suppl. List. Melamp - 
soropsis cassandrae Arth.) Aecia ( Peridermium 
consimile Arth. & Kern) on Picea Mariana Mill. 
Oneida (Cheney) and Vilas counties, Waupaca 
and Gordon. The two first mentioned collec¬ 
tions were reported as Peridermium decolorans. 
Pk. in the 3d suppl. List which species, however, 
has also been collected in Vilas county. 
490. Lender this number in the supplementary list was reported 
the collection in small quantity of Protomyces 
macrosporus Ling, on Cicuta maculata L. and 
reference was made to the fact that considerable 
search had been made to find more of it but with¬ 
out success. Reexamination of the specimen 
leads me to the conclusion that it is really 
Cladochytrium maculare (Wallr.) on a scape of 
Alisma Plantago L. 
491. TuBURcmiA clixtoxiae Kom. 
Collected in small quantity in Douglas County on 
Streptopus roseus Michx. This fungus was in¬ 
cluded in the supplementary list under the name 
Tuburcinia trientalis B. & Br. the host being given 
as Smilacina. On reexamination however I am 
constrained to believe that Streptopus roseus is 
the host of that collection also. It is somewhat 
curious that these two collections, with a time in¬ 
terval of 21 years, were made in the south eastern 
and north western corners of the state. 
492. Tuberculixa persicixa (Ditm.) Sacc. 
On Lupinus perennis L. Adams county. This is the 
only evidence that I have seen of the occurrence 
of a rust on Lupinus in Wisconsin.
