the hyphae ascend the trichomes, developing lateral conidiophores 
and profuse conidia. In the leaf tissue is a fine (l^jt-0 hyaline 
mycelium which is apparently nonseptate. Microscopically this 
fungus resembles Plasmopara halstedii (Farl.) Berl. & De Toni, 
for which it was mistaken in the field. This is another of the 
Sporotrichum-like forms but whether it is a saprophyte, a leaf 
parasite, or a parasite on Plasmopara, I do not know. [In a 
collection made at Chaseburg in August, 1920, the hyphae are all 
hyaline and the stromata small, loose, and hyaline. Some of the 
longer conidia have a median septum, and one was observed hav¬ 
ing 3 septa.]

This was collected a number of times on Scirpus atrovirens at 
Kacine but not identified. It occurs also at Madison on the same 
host.

In this collection the sporules are 40-60/x long.

Under the name Aecidium smilacinae, (error for maianthae) two 
species of Aecidium were confused in the provisional list. One 
of them, Aecidium magnatum Arth., has been connected with a 
race of TJromyces acuminatus Arth. on Spartina Michauxiana to 
which the name TJromyces magnatus Arth. has been given (Myco- 
logia 9: 309-12). The aecial hosts of this in Wisconsin as far as 
known at present are Smilacina racemosa, S, stellata, and Polygo- 
natum. The Aecidium on a leaf of Oakesia sessilifolia collected 
at Hancock I am also referring to this species. Of the four races 
of TJromyces acuminatus Arth., three occur in Wisconsin. The 
least unsatisfactory way of designating these, as it seems to me, 
is by the use of trinomials, thus: 
TJromyces acuminatus magnatus (Arth.) 
TJromyces acuminatus steironematis (Arth.) This form appears 
to be rare in Wisconsin.
