Rt:MARKS. The species of Puccinia hitherto known to be parasitic on 

 the Japanese l^ambusea: are Puccinia Kiisanoi, P. Phyllostaciiydis, P. longi- 

 coritis and /'. 5^5«". 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 arc 

 distinguishable from each other. The apex of the teleutospore of the present 

 species is conically elongated reaching nearly 90/; in length, while that of 

 Puccinia longicornis is cylindrically elongatetl attaining about 38//. 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 urcdostage of this 

 fungus is not yet obtained.

Remarks. This species was described by Prof Kus.ANO from the 

 specimen collected at Nikko by Mr. T. Makixo. This species is said to 

 resemble Puccinia Phyllostachydis in general appearance, but it differs in 

 the upp:r cell being wider and shorter than the lower, and also in its para-
