of tlic thickened apex, the g-cneral form of tlic spore approaches rather near 

 to Puccinia longicoriiis tlian to Piicciiiin Kusaiioi, as has ah-eadj- remarked 

 by Prof. KUSANO. 



I have also found mixed in one and same sorus of the variet}' some 

 teleutospores closely resembling the t)-pical spores of Pncciiiia Kusanoi.

Remarks. This species isireadil)- distinguished from Puccinia Kusanoi, 

 P.SaSLCd^wA P. Pliyllostachydis by the cylindrically elongated apex of its 

 teleutospore (13-32//. sometimes 38// in length), and the presence numerous 

 clavate paraphyses in the uredosori. By Dietel (9), this species is recorded 

 as parastic on Phyllostachys bambnsoidcs S. et Z. ( = /*. Quilici Riv.), col- 

 lected by Mr. Vosiiix.vga in Shikoku. From m\- own obscr\-ation, the 

 fungus does not attack any species o^ Pliyllostacliys.
