GRIFFITHS: West AMERICAN FuncI 299 
Puccinia micrantha sp. nov. 
Sori epiphyllous, with both uredo- and teleutospores produced 
in the same sori which are usually short, linear or circular, scattered 
evenly over the surface, conspicuous, black, prominent, without 
visible remains of ruptured epidermis ; uredospores subglobose, 
minutely, rather sparsely but evenly echinulate, 15~17 yu in diame- 
ter, the epispore rather thick and prominent in optical section ; 
teleutospores very variable, obovate to oblong-elliptical, very 
slightly to conspicuously constricted at the septum, the base 
rounded, the apex broadly rounded or long-pointed, strongly thick- 
ened, 13-24 4 x 30-45 4; pedicel once to twice the length of the 
Spore, hyaline or slightly tinted at the base of the spore. (Fig. 8.) 
On living leaves of Oryzopsis micrantha (T. & R.) Thurb. (3 86), 
Billings, Mont., Sept. 1898 (Williams & Griffiths). This is such 
@ common and familiar species to me that it is with considerable 
hesitancy that it is given a distinct name. It seems almost impos- 
sible that it has not been collected by others; but careful search 
has not revealed a record of it. It was first collected by Griffiths 
and Schlosser at Forest City, South Dakota, in 1892 and subse- 
quently in the same locality in 1897 by Griffiths and Carter. Speci- 
Mens from the first collection are in herbaria of the writer, the 
agricultural college of South Dakota and the agricultural college 
of North Dakota. There was also a specimen in the private her- 
barium of the late Professor T. A. Williams. A large sheaf of 
the host, all badly rusted, was collected and deposited in the col- 
lection of the agricultural college of South Dakota in 1892. It 
Was the intention to have put it up for distribution, but judging 
from the notes on p. 74 of bulletin no. 40 of that institution it may 
have been all destroyed except the specimens cited. Frotessor 
Bolley, to whom specimens were submitted, reported at the time 
that the fungus had ‘characters of its own.” Although reniem- 
bering the specimen, he is unable, owing to removal to new quar- 
ters, to find it now. 
Aecidium grindeliae sp. nov. 
Aecidia usually clustered in brown somewhat thickened areas 
Of the leaf tissue, occurring about equally on both sides of the same 
Spot, each cup forming a distinct papilla having finally a circular 
°r oval or lenticular opening through which the spores escape, 
© peridium not projecting beyond the raised epidermis of the
