erect, more or less geniculate, septate, sometimes branched, 
60-70x6-7)a; conidia ferruginous, lanceolate, 6-8 septate, tapering 
into a flagelliform distal portion about as long as the body, 
100-165xl3-7/>i. On leaves of Froelichia floridana, Lone Rock, 
Wisconsin, July 23 and 25, 1921. The spots are sometimes very 
abundant but mostly sterile. It is not unlikely that vertical septa 
appear at full maturity and that this therefore is an Alternaria 
like A. crassa (Sacc.) Rands (Cercospora crassa Sacc.) which it 
resembles in its conidia. 
Cercospora cucu7'l)itae Ell. & Evht. A parasite on leaves of 
Cucurhita maxima (cult.) collected at Madison, I have referred to 
this species although it is quite different from the type in appear¬ 
ance. In the Wisconsin material the spots are suborbicular, brown, 
with a distinct darker border above, whitish and immarginate 
below, 2-5 mm. in diameter, sometimes confluent; conidiophores 
scattered or in small tufts, amphigenous, fuscous, somewhat curved, 
sometimes septate, simple, more or less denticulate especially near 
the apex, 70-130x3-4ju,; conidia flagelliform, straight or the slender 
distal portion curved, septate, hyaline, 87-123x3/x. It was collected 
in October. 
Uromyces perigynius Hals. var. altiporulus n. var. Uredinia 
brown, erumpent, elliptical to linear 0.2-1 mm. long; uredospores 
brown, globose to elliptical, ovate, ohovate or oblong, wall brown 
1-1%/x thick, echinulate, 12-23xl2-15/>i, germ pores two, variously 
situated in the upper half of the spore; telia similar but darker; 
teliospores obovate to subfusoid, brown, rounded or often conical 
at the apex which is strongly thickened (up to 10/x), pedicel hyaline 
as long as the spore or longer. On leaves, bracts and perigynia 
of Carex Gi^ayii, Blue River, Wisconsin, August 9, 1922. I am 
keeping this collection separate because the germ pores are uni¬ 
formly further from the equator than in JJ. pe^dgynius as I have 
seen it and as it is described. Often one pore lies higher than the 
other, sometimes both are subpolar. 
Happening to be in a locality in which Aecidium allenii Clint, 
was abundant on Shepherdia canadensis attempt was made to get 
a clue to the alternate stages. The infected Shepherdia was 
confined to the small valley through which the waters of Fish 
creek flowed into Green Bay. The first step was to find a host 
having the same habitat as the Shepherdia and Carex ehurnea was
