Davis—Notes on Parasitic Fungi in Wisconsin — VI. 711 
Whitehall, Wisconsin, July 27, 1916. I have referred this, with 
some doubt, to Metasphaeria chaetostoma Sacc. var. urticae 
Rehm. 
Keithia tsugae Farl. occurs on Tsuga canadensis in Wisconsin 
but has not been included in these lists because of doubt as to 
its parasitism. It has been found only on dead leaves at¬ 
tached to dead twigs. More favorable opportunities for ob¬ 
servation however lead me to surmise that the death of the twigs 
is caused by the organism that sporulates on the leaves. The 
appearance of an infected tree reminds one of fire blight. It 
was especially abundant at Two Rivers in 1917. 
Lophodermium juniperinum (Fr.) De Not. On Juniperus 
communis depressa. Two Rivers. 
Phyllosticta boehmeriicola n. sp. Spots suborbicular, 
olivaceous with a darker margin and pale, sordid, central por¬ 
tion, 3-10 mm. in diameter; pycnidia epiphyllous, scattered, 
lenticular, succineous, ostiolate, 100-150/x; sporules oval to ob¬ 
long, fuligenous tinted, 4-7 x 2-3 y. On leaves of Boehmeria 
cylindrica. Shiocton. August 1917. 
Phyllosticta minutissima Ell. & Evht. On Acer saccharinum; 
accompanied by Phloeospora aceris. Shiocton. 
Phyllosticta ulmicola Sacc. Under this name I am recording 
the occurrence of a fungus having the following characters: 
Spots definite, immarginate, orbicular, light brown becoming 
cinereous above and lacerate, finally falling away in fragments, 
3-7 mm. in diameter, sometimes confluent; pycnidia epiphyllous, 
scattered, black, globose to depressed-globose, 60-80/x; sporules 
globose to elliptical, olivaceous-hyaline, continuous, 3-6 x 2-3 y. 
On TJlmus americana. Tisch Mills August 3, 1917. Ulmus 
racemosa August 5, 1917. This is probably a member of a 
group to forms of which various names have been applied in 
Europe and America. 
Phyllosticta mitellae Pk. On Mitella diphylla. Melvina. 
In the collection that I am provisionally referring to this species 
the pycnidia are light brown and the sporules oblong to ellipti¬ 
cal, 4-6 x 2-3 fx. Occasional sporules have a median septum. 
Ascochyta nepetae n. sp. ad interim. Spots orbicular to 
elliptical, olivaceous usually with a narrow darker margin, 4-10
