maea var. fusca (Pk.). I take it that the state with local infec¬ 
tions and both spore forms is the older and that the others have 
been derived therefrom. 
Synchytrium scirpi Davis on Scirpus atrovirens previously 
known only from the vicinity of Racine was collected at Oconto in 
September, 1921, mostly in an abortive state, presumably because 
of the hot, dry summer. In examining sections of the leaves what 
appeared to be a Sphaerulina was observed and the following notes 
made: Perithecia sparse, innate, black, globose, 85-lOOjtJi in diam¬ 
eter; asci sessile, fusoid-cylindrical, 60-70xl6-18/x; spores long 
fusoid, slightly curved, hyaline, obtuse, 5-septate, 35-40x5-6/a; 
paraphyses none; The inconspicuous perithecia are too few to 
warrant taking the material as a type. [In 1922 Synchytrium scirpi 
was collected on the same species of host opposite Sauk City. There 
is also a specimen from Little Suamico.] 
Sept or ia rubi West, was found by Roark to have an ascigerous 
stage for which he proposed the name Mycosphaerella rubi (Phyto¬ 
path. 11:329, [1921]. Although the Septoria is abundant through¬ 
out the state he was able to find the Mycosphaerella only in Door 
county which lies between Green bay and lake Michigan. 
Piggotia vaccinii Davis (“Notes” IX, p. 436, fig. 3) is doubtless 
conspecific with Leptothyrium conspicuum Dearn. & House (A. Y. 
State Museum, Report of the Botanist for 1919, p. 37, [1922] and is 
antedated thereby. 
A parasite of Gentiana Andrewsii was collected in Wisconsin 
thirty odd years ago and sent to Ellis who identified it as Depazea 
gentianaecola Pr., but referred it to Phyllosticta (see N. A. Phyl- 
lostictas No. 176) and it was so recorded in the supplementary list. 
Baeumler in 1889 recorded as Leptothyrium, a fungus on Gentiana 
which he supposed to be the same as the one treated by De Can¬ 
dolle and Pries and used the specific name proposed by De Candolle. 
In compiling the provisional list there was no time to investigate 
such matters but simply to follow the Tom Johnson rule, “decide 
at once and be right half the time. ’ ’ On the principle that things 
that were equal to the same thing were equal to each other I used 
Baeumler’s binomial. Dr. Brenckle sent me a specimen from North 
Dakota and I wrote him that it was the fungus recorded in the 
provisional list under the name Leptothyrium gentianaecolum 
(DC.) Baeuml. and he issued it in Fungi Dakotenses under that
