This species has been made to include both S. Syntherismae and 
S. Everhartii by some botanists. Winter described the species 
fiom specimens on both Andropogon Virginicus and Aristida 
dichotomy The form on the latter host seems to differ somewhat 
from that on Andropogon and possibly may merit distinction. The 
gei ruination has not been reported. The form reported from Con¬ 
necticut on A. scoparius is very near £. Everhartii which also 
occurs in that State on the same host.

Exsiccati: Sorosporium Ellisii var. provinciale , on Andropogon provin-

Son in the inflorescence, linear, often 6 cm. or more in length, 
concealed within the leaf sheath or upper part protruding, with false 
membrane that becomes lacerated exposing black brown, granular 
spore mass; spore balls variable, apparently gradually wearing 
away, chiefly 50-100/x, or possibly even longer 1 ; spores medium 
light reddish brown though often darker in places, rather regular, 
ovoid to chiefly subspherical, minutely verruculose, with thick uni- 
foim cell wall (3 ^,), 14—19 p in length. 
Host: Andropogon furcatus , Mo. (type), Neb. 
This seems entitled to specific rather than varietal rank since it is 
the most sharply marked off of any of these closely related forms 
on Andropogon. It is distinguished by the uniform spores with 
very thick walls. The germination has not been reported. Litera¬

Soii taking the piace of the aborted inflorescence, linear, usually 
enclosed in the leaf sheaths, forming an agglutinated brown black 
spore mass; spore balls reddish to black brown, usually opaque, 
ovoid to spherical, quite firm, composed of 6-20 or more spores, 
1 Ellis gives spore balls as : ~35-150 
fj. or oblong 100-200 fx X 75-80 p..
