341. Glceosporium piiegopteridis, Frank. 
On Onoclea sensibilis, L., and Aspidium Thelypteris, 
Swartz. Racine. Sometimes abundant on the 
first mentioned host. On the Aspidium it does 
not seem to develop so perfectly. 
342. Glceosporium prunicolum, E. & E. 
On Prunas Virginiana, L. Racine, Abundant, 
but apparently not common. 
343. Glceosporium potentill^, (Desm.) Oud. 
On Potentilla palustris, Scop. Kansasville. 
344. Glceosporium rtbis, (Lib.) Desm. & Mont. 
On Ribes floridum, L., and wild and cultivated 
gooseberries. Racine. Abundant.

346. Glceosporium saccharinum, E. & E. 
On Acer saccharinum, Wang. Racine and Wauke¬ 
sha. Destructive to the leaves of city shade trees; 
sometimes very much so. On forest trees it is 
much less common and usually confined to definite 
spots on the leaves.

On leaves of Vicia Americana, Muhl. Berryville.

On Hamamelis Virginiana, L. Racine. 
349. Heterosporium allii, Ell. & Martin.
