 REMABKS :— This sptcies is also endemic to our countrv. KUSANo's original 

 description is said to liave reached DiETEL, while his paper on Phragmidiuin in 

 1905 was iu the press. However, DiETEL made a short remark on this species 

 imder Ph. JRubi (Pers.^ Vriiit. v:ir. minkdum J. Müll., siiying "Als eine neue, in 

 dieser Arbeit noch nicüt beriicksichigte Art erhielten wir während des Druckes 

 noch PI). Pubi-T.tunbergii Ivusano atif Pvbu.9 Thunbciyii S. et Z. aus Japan. Sie 

 Lst den anderen japanischen Art sehr ähnlich". But nobody will think, that the 

 present species is allied to Ph. Pubi 'Pers.j Wint. var. miniafitm J. Müll., when 

 he once observed the smootli epispore of the former. In reality, the smoothness of 

 the epispore of Ph. Pubi-Thunbergii Kusano was not mentioned iu the original 

 descriptiim of this species. Through the kiuduess of Prof. M. SHIRAI I got a 

 specimen of the teleuti>stage of the present species. Under tlie microscope the teleu- 

 tosp>re disclosed its resemblance to Ph. griseum Diet, in the character of the pa- 

 pillatetl apex and of the ctmstrictiou at septum. But. as the author of the species 

 well noticed in his remarks, the number of the germ-pores in each cell are '2. while 

 in the case of Ph. gris^um they are generally 3. Tlie length of the pedicel of 

 the present species is also always shorter than that of Ph. griseum
