Davis—Notes on Parasitic Fungi in Wisconsin — VII. 409 
late, 30-50 x l~V/ 2 y. On leaves of Coreopsis palmata. Hixton, 
Wisconsin, September 1, 1917. 
Specimens on Chrysanthemum Leucanthemum from Bailey’s 
Harbor that I have referred to Septoria chrysanthemi Allesch. 
bear spornles mostly 60-70/x long. 
Leptothyrium pomi (Mont. & Fr.) Sace. 
On fruit of Pyrus Malus. Sparta (L. R. Jones). 
Gloeosporium equiseti Ell. & Evht. 
On Equisetum sp. indet. Sullivan. The sporules remind one 
of the sporidia of Entyloma. 
Gloeosporium balsameae n. sp. (Plate XXX). 
Acervuli hypophyllous, subepidermal, orbicular to oblong, J / 2 -l 
mm. in length; sporules hyaline, continuous, fusoid, often in¬ 
equilateral, seldom curved, 16-33 x 4-6/x, borne on hyaline basidia 
of about the same length. The affected leaves have the lethal 
color throughout, the presence of the fungus being indicated only 
by the epidermis being slightly raised over the acervuli. This 
epidermal covering apparently becomes cut away at the peri¬ 
phery and detached in one piece. 
On Abies balsamea, Clark lake, Door county, July 22,1918. 
Ramularia destructans Zinssmeister and R. panacicola Zinss- 
meister are reported by the author as occurring on roots of Panax 
quinquefolium at Wausau (Phytopath. 8: 570). 
Ramularia minax n. sp. 
Spots small, angular, black, y 2 -l mm. in diameter; conidiophores 
predominantly hypophyllous, subulate to cylindrical, usually con¬ 
tinuous, sometimes denticulate near the apex, 6-24 x 2y 2 -3y 2 n 5 con- 
idia hyaline, straight, fusiform to cylindrical; acute, 10-23 x 2y 2 -4ju. 
On leaves of Solidago rigida. Buffalo County near Arcadia, Wis¬ 
consin, September 5, 1917. 
Superficial repent hyphae become closely septate and brown, 
contorted into brown knots 15-30/*, in diameter, forming superficial 
tubercularioid pseudostromata from which the conidiophores arise 
as lateral branches of the component cells, the basal portion of 
the conidiophore sometimes showing some of the brown color of 
the cell from which it sprang. Sometimes, however, the brown, 
or sometimes hyaline, septate hypha is extended along the leaf 
surface, giving off condiophores as short lateral branches. Often
