REMARKS. In his monograph, SYDOW has described five species of Pucciiiia 

 parasitic on Caltha, in which two species have teleutospores with smooth epispore, 

 P. Calthae Link and P. gemclla Diet, et Holw. 



The teleutosori in our specimen are irregularly scattered over both surfaces oi 

 the leaf, small, roundish in shape. At first they are covered by epidermis, soon 

 after naked, powdery and brownish black in colour. Uredospores are often 

 mixed in the sori. Uredospores are subglobose, globose or ellipsoidal, echinulate, 

 yellowish brown, 24 34.5 x 19 25 //,. The germ-pores are two on the upper half of 

 the spores. The teleutospores are clavate, oblong-clavate or fusiform in shape, mostly 

 somewhat attenuated at both ends, not or slightly constricted at the septum, 

 smooth and chestnut-brown in colour. Typical ones measure 32 48 x 14.5 23 p,. 

 The germ-pore of the upper cell is at the apex, that of the lower is just below the 

 septum, each pore is pro.vided with a hyaline, conical or flattened pnpilla. Pedicels 

 are hyaline and persistent, and" often attain the length of 58 //.. 



These characteristics coincide exactly with the descriptions of Puccinia Calthae 

 by many European authorities. Although I was not able to observe any JEcidium 

 and uredosorus in our Saghalien specimen, there is no doubt of its being identical 

 with the European species. This fungus is not yet found in other parts of Japan.
