Davis-—Notes on Parasitic Fungi in Wisconsin— X, 28J. 
Phyllosticta pyrolae Ell. & Evht. Collected in small quantity 
and not quite mature on leaves of Pyrola elliptica at Blue Mounds. 
Phyllosticta steironematis Beam. & House. On 8teironema cilia- 
tum. Lone Eock. 
Phyllosticta verbascicola Ell. & Kell. On Verhascum Thapsus. 
Barneveld. 
Phoma alliicola Saec. & Eoum. A collection on Allium canadense 
from Madison is referred to this species. The ostiole is often gap¬ 
ing, the sporules 4--6x2~3fi. 
Macrophoma arens n. sp. Pycnidia black, scattered, subepider- 
mal, globose, 130”150ft in diameter; sporules narrow ovoid, becom¬ 
ing subfuligenous, 27xl0/x at maturity. On more or less of the 
distal portion of leaves of Koeleria cristata which become sere and 
involute. Boscobel, Wisconsin, July 5, 1921. 
Asteromella astericola n. sp. Pycnidia epiphyllous on indefinite 
purple areas in compact orbicular groups, black, globose, 100-165ju, 
in diameter; wall parenchymatous of dark firm cells 6-10/x in diam¬ 
eter; sporules sessile (?), hyaline, terete to fusoid-cylindrical, 
mostly straight, 20x30x3-4/x. On Aster lateriflorus, Blue River, 
Wisconsin, August 3 and 4, 1921. It may be that this is a better 
developed form of Asteromella asteris Pk. {Report for 1912, p. 38). 
Stagonospora albescens n. sp. Spots orbicular, sordid white, 
%-2 mm. in diameter surrounded by a broad indeterminate reddish 
brown border; pycnidia few, innate, dark brown, globose, thick 
walled, about 150/i, in diameter; sporules hyaline, fusoid-cylindri¬ 
cal, straight or sometimes curved, 5-7 septate, 45-67xl0-13ju. On 
living leaves of Carex tribuloides. Muscoda, Wisconsin, October 
1920. Macroscopically this resembles Septoria caricinella Sacc. 
sufficiently to have been mistaken for it in the field. The contents 
of the cells or cytoplasmic divisions are homogeneous. 
May 13 and 19, 1921, spots were observed on leaves of a few 
plants of Melilotus alba at a station near Madison. The following 
notes have been made from these collections: Spots definite, circular 
to elliptical to irregular, argillaceous with a paler center, 1-10 mm. 
in diameter; pycnidia in the paler area, hypophyllous, exception¬ 
ally epiphyllous also, brown, globose to lenticular, ostiole circular 
with a dark margin about 30/x across, 135-165 /a in diameter;
