SOROSPORIUM PROVINCIALE (Ell. & Gall.) Clint, n.. 
sp.—Sorosporium ellisii var. provincialis Ell. & Gall., Journ. 
Mycol. 6:31-2. 1890. 
Sori in the inflorescence, linear, often 6 or more cm. in 
length, concealed within the leaf sheath or the upper part pro¬ 
truding, with false membrane that becomes lacerated as exposed 
and with black brown granular spore mass; spore-balls variable, 
apparently gradually wearing away, chiefly 50-100 /* or possibly 
even longer; spores medium light reddish brown though often 
darker in places, rather regular, ovoid to chiefly subspherical, 
minutely verruculose, with thick (3 t* ) uniform cell wall, 14-19 
in length. 
Host: Andropogon furcatus, Mo. (type), Neb. 
This species is based on specimens No. 2425 in Ell. & Ev. 
N. A. F. It seems entitled to specific rather varietal rank as it 
is the most sharply marked off of the related species on Andro¬ 
pogon. It is especially distinguished by the thick uniform walls 
of the spores.
