not confluent, naked, pulvinate, prominent, compact, thick, sooty-black or 
brownish-black. Teleutospores, oblong-clavate or fusiform, apex extraordi- 
narily conically elongated (36-84 fx, sometimes go/x in length), subacute, 
base somewhat attenuated, not or slightly constricted at the septum, smooth, 
light yellowish-orange or whitish-yellow, hyaline or lighter colored at the 
tip of apex, 80-130x18-23,«; pedicels hyaline, fine, extraordinarily long, 
( 100-240//, sometimes 280,«), slender, subdeciduous. Mesospores are fre- 
quently mixed in the sori.

REMARKS. The species of Puccinia hitherto known to be parasitic on 
the Japanese Bambuseae are Puccinia Kusanoi, P. Phyllostachydis, P. longi- 
cornis and P. Sasce. A fifth species is here added, based on the specimen 
obtained from Prof. G. Yamada. It grows on Sasa paniculata. At first 
sight it is quite indistinguishable from Puccinia longicornis macroscopically. 
It is only when examined under a microscope, that these two species are 
distinguishable from each other. The apex of the teleutospore of the present 
species is conically elongated reaching nearly go/x in length, while that of 
Puccinia longicornis is cylindrically elongated attaining about 38 [x in its 
maximum length. Moreover, the teleutospores of the former species are 
slightly constricted at the septum, with extremely long slender subdeciduous 
pedicels, and also with many mesospores intermixed. I regard this fungus 
for the above mentioned reasons as a new species. The uredostage of this 
fungus is not yet obtained.

REMARKS. This species was described by Prof. KUSANO from the 
specimen collected at Nikko by Mr. T. MAKINO. This species is said to 
resemble Puccinia Phyllostachydis in general appearance, but it differs in 
the upper cell being wider and shorter than the lower, and also in its para-
