Davis—Notes on Parasitic Fungi in Wisconsin — IV. 677 
For want of another I used in the provisional list the name 
Puccinia impatientis Arth. for a species forming uredinia and 
telia on Elymus. For this I suggest the designation Puc¬ 
cinia elymi-impatientis nom. nov. For the rnst given in the 
provisional list as Puccinia albiperidia Arth. I am now using the 
name Puccinia pringsheimiana Kleb. as there seems to be no rea¬ 
son for considering the American rust as distinct from that of 
Europe. 
ADDITIONAL HOSTS 
Albugo Candida (Pers.) Kuntze. On Dentaria diphylla. 
Laona. Oospores only; in leaves. 
Basidiophora entospora Roze & Cornu. On Erigeron canar- 
dense. Long Lake. Monstrous conidia, up to 63 x 30y., with 
suppression of conidiophores were found in this collection (Cfr. 
Farlow, Botanical Gazette 7: 311). 
Peronospora potentillae D By. On Agrimonia mollis. Lynx- 
ville. 
Peronospora trifoliorum D By. Collected in small quantity 
on Lupinus perennis at Millston. 
In “Notes” I, p. 85 mention was made of the collection of 
Synchytrium at Athelstane on Rubus Jiispidus and on no other 
host. The station was visited again in July, 1915, but the 
organism was not found on Rubus. It was found however, in 
small quantity, on Viola conspersa and on a single leaf of 
Clintonia borealis. In August collections were made at Solon 
Springs on Viola conspersa, Halenia deflexa, and in small 
quantity on Rubus triflorus. It may be that these represent 
more than one species but the effects of stage of development, host 
and environment have not been worked out.

cernua. Madison.
