Davis—Notes on Parasitic Fungi in Wisconsin — V. 697 
seems to be so like the form on Elymus as to indicate specific 
identity. There is a Phyllachora asprellae Roum. & Fantr. in 
France the asci and spores of which are described as being larger. 
Panicum latifolium: Asci 65-80x9 /a; spores 8-9 x 4-5/*. A 
later collection: Asci 60-70 x 8-12/*; spores 9-11 x 5-6//,. 
Panicum huachucae: Asci 50-60 x 6-9/a; spores 8-9 x 4-5/*. 
Panicum sp. indet.: Asci 57-63 x 9 /a ; spores 7-9 x 5/*. The 
Panicum specimens appear conspecific and are what has been 
distributed in this country as Phyllachora graminis var. panici 
(Schw.) Shear. If they belong with any of the species de¬ 
scribed by Theissen & Sydow as occurring on Panicum it is 
probably thq South American Phyllachora panici (Rehm). 
Muhlenbergia: Asci 50-67x5-6/*; spores 6-8 x 4/a. This is 
probably Phyllachora vulgata Theiss. & Syd. (loc. cit. 450). 
Agropyron repens: Asci 60-80x6-8/*; spores 8-12 x 4-5/a. 
Calamagrostis canadensis: Asci 51-72 x 5-6/a; spores 7-9 x 
5-6/*. Phyllachora has been observed in northern Wisconsin on 
Oryzopsis asperifolia but no mature specimens have been pre¬ 
served. This is presumed to be Phyllachora oryzopsidis Theiss. 
& Syd. (loc. cit. 451). 
Taphrina coryli Nishida. On leaves of Corylus americana. 
McFarland, Madison, Sparta, Melvina, Hixton, Taylor, Blair, 
Whitehall. In 1916 this was found scattered about through 
the woods in western Wisconsin in a way that left no room for 
doubt as to its being indigenous. The appearance in the field 
suggests Microsphaera. 
Of a collection on leaves of Echinocystis lobata made at White¬ 
hall, July 28, 1916, the following notes were made: “Spots 
suborbicular, immarginate, pale brown, y 2 -l cm. in diameter; 
pyenidia scattered, lenticular, succineous, ostiolate, 75-100/a; 
sporules hyaline, oval to oblong, 4-8 x iy 2 -S^. Accompanying 
Plasmopara australis (Speg.) Swingle and perhaps secondary.” 
I have referred it to Phyllosticta orbicularis Ell. & Evht. 
Sphaeropsis betulae jCke. var. 'foliicola n. var. On large, 
light brown dead leaf areas; pyenidia mostly epiphyllous, scat¬ 
tered or aggregated, blackish brown, depressed-globose, black¬ 
ened about the ostiole, 100~150/a; sporules oblong with rounded
