KL\,SAl-ON THE J.\PA^'ESE SPECIES OF PHRAGMIDIUM. 35 



Teleutospore brownish-black yellowisli- brown 



Xiimber of cells 4—9 7-11 



General form fusiform or subcvIinJrical eylimlrical 



Papilla long fiC-l'i mmm. very short A-6 mmm.^ 



Pedicel conspicuously bulbous slightly inflated 



(100-120 mmm. long) 150 mmm. long) 



Remarks : From Fh. i/czoense n. sp. this species differs by the wloiir of 

 its teleutosori as w 11 as by that of the teleutospore.^. . The general form of the 

 teleutospores and the shape of papilla also show sharp points of their di.ssimilarities. 

 The characteristics of Fh. Hosae-nigosae n. sp lie in the very short papilla, a 

 cylindrical outline and also in the brownish-yellow color of its teleutospores. I have 

 often uotic-ed that in the lower part of the palicel, where fine spiral striation often 

 comes to view, the outer portion of the wall, on a long treatment with potash or 

 water, swells up and melts away leaving the innermost layer of the wall compa- 

 ratively unchanged.

 of leaves, small, densely scattered or crowded, black 'not browu;, readily detachable ;
