of the thickened apex, the general form of the spore approaches rather near 
to Puccinia longicornis than to Puccinia Kusanoi, as has already remarked 
by Prof. KuSANO. 
I have also found mixed in one and same sorus of the variety some 
teleutospores closely resembling the typical spores of Puccinia Kusanoi.

Remarks. This species is readily distinguished from Puccinia Kusanoi , 
P. Sasce and P. Phyllostachydis by the cylindrically elongated apex of its 
teleutospore (13-32/2 sometimes 38/2 in length), and the presence numerous 
clavate paraphyses in the uredosori. By DlETEL (9), this species is recorded 
as parastic on Phyllostachys bambusoidcs S. et Z. (=P. Quilici Riv.), col- 
lected by Mr. YOSHINAGA in Shikoku. From my own observation, the 
fungus does not attack any species of Phyllostachys.
