Puccinta Crapu EIl. & Tracy. 
On Cladium effusum, Ocean Springs, Miss., Aug., i889 (Prof. 
S.M. Tracy). II. & III. 
On the culms and peduncles of the cyme. -Sori small, ellip- 
tical, subconfluent, so as often to envelope and cover the peduncles 
for 2 or more cm. in extent; at first covered, then bérdered by the 
ruptured yellowish epidermis. Uredospores ovate or elliptical, 
22-25 X20 #, or subglobose, 18-20 #, at first hyaline, then deep red- 
brown (or ferruginous-yellow while lying in the sori) aculeate. 
Teleutospores in similar but much darker colored sori, clavate or 
oblong, 45-60X18—22 «, constricted, deep brown, lower cell nar- 
rower and paler, epispore smooth or slightly granular-roughened 
above, strongly thickened at the obtusely rounded apex, or with 
an oblique papilla, or sometimes subtruncate-flattened. Pedicels 
shorter than the spores, hyaline or slightly colored, stout. The 
uredospores are also pedicellate. 
PUccINIA GRANULISPORA Ell. & Galloway. 
On stems and leaves of Alum cernuum? Montana, 1890 
(Prof. F. D. Kelsey). ; 
II. and III. Sori linear, 4-1 cm. long, shorter on the leaves, 
¥% mm. wide, at first covered, then exposed by a longitudinal 
cleft in the epidermis, but only slightly prominent. Uredospores 
Subglobose, pale, faintly echinulate, 20-30X15~-20 #. pepe 
spores oblong, clavate or obovate, 45-60%20-25 /, smooth, wit 
granular contents, slightly constricted, upper cell subglobose re 
elliptical, darker, moderately thickened at the rounded or ae 
pointed or often truncate apex, lower cell paler, cuneate. Pedicels 
shorter than the spores, colored. Mesospores not abundant, 
shorter, obovate, 20-23 / long. 
Differs from P. Porri in its linear sori and larger teleutospores. 
AEcIpIum cytinpricum E. & E. 
On leaves of Houstonia angustifolia, Osborne, Kansas, June, 
Da hyll bseriate along each 
Spe ia? Aecidia hypophyllous, subseriate ¢ 
sae ithe AGEs white, atc about 1 mm. high, sini 3 
minutely subfimbriate-dentate. Spores orange-red, angular-g “di 
bose, smooth, 18-22 #. The upper side of the leaves is ange io 
less blackened and papillate from the projecting bases of the 
aecidia. . : = 
‘Differs from Accidium houstoniatum Schw. in its elongated, cy- 
lindrical aecidia.
