 REMARKS:— This is also one of our endemic species described by DiETEL 

 in 19');-]. Among the few specimens I have had the oeer.!-:'on to examine, the one 

 received I'rom S. KüS.\NO may be regarded as the best re[>resentative of the type. 

 It lias two germ-pores in tlie uppermost cell of the teleutospore, situated ;i httle 

 above the middle of the cell, while in the other cells there are three set ch)sely 

 under the septum. The general character of the teleutospore bears much resem- 

 blance to that of F/i. YosMnagai Diet, DiETEL holds the length, the paj)illum 

 and the constriction at septum as the distinctive points of their teleutospores. But 

 many well constricted and conically papillatcd teleutospores of Fh. Yo.sJnnagcd 

 Diet, have come under my observation which seem to stand in contradiction to 

 DiETEL's remarks to a certain degree.

 tlEMAEKS:— Tliis species is also endemic to our country. The first account 

 of it was given by DIETEL in 19! 'o after examining the specimen collected by S. 

 KUSANO at Ito, Prov. Izu. The materials I have examined were all in the ure- 

 do.stage. DiETEL made remarks concerning the affinity of this sjiecies with J'lt. 

 obtiisam (Strauss) Wint. I have, however, iiardly, any thing to say on tJiis species, 

 as I have not been able to observe the teleutospores myself.
