adhere in pairs have the appearance of Schizonella. Often some of 
the largest spores appear to be sterile cells merely. The species 
described by Ellis and Everhart on Geum is not distinct. Litera¬

S °ii ^ eaves 5 petioles, and stems, forming conspicuous pustules 
of varying shape and size, upon rupture disclosing dusty brown 
black spore mass ; spore balls irregular, apparently separating some¬ 
what into the sterile cells and spores, usually 22-35 p, rarely 45 p, 
in length ; sterile cells usually incompletely covering the spores' 
often only on one side, smoky brown or yellowish tinted, ovoid to’ 
spherical, usually thin walled, about 8-14 p in length; spores red¬ 
dish brown, irregular, oblong or ovoid to polyhedral or subspherical, 
smooth, 1-5 though usually only 1 or 2 in a ball, chiefly 12-17 p 
rarely most elongated 20 p, in length.

1 Since the above was written the writer has been informed by Dr. Thom 
that he has succeeded in germinating the spores and the germination is of the 
Ustilago rather than of the Urocystis type. This makes the species come under 
the former genus.
