Notes on the Japanese Fungi. 



II. SOME SPECIES OF UREDINE/E. 



BY 



S. Eusano. n. sp. 



Puccinia Cacaliae Kusano. 



Teleutosori hypophyllous, isolate, irregular, 1— | mm. in diameter, 

 naked, pulverulent, black ; spores oblong or fusiform, slightly rounded at 

 the upper end, mostly tapering towards the lower end, constricted at the 

 septum, with upper cell broader than the lower, wall thickened at the 

 apex, forming conical papilla (15 fi), smooth, brown, 55-63 x 18-23 ji ; 

 spores with longer pedicel short, hyaline or pale. 



On the leaves of Cacalia Syneilesis (Fr. et Sav.) (=Seitecio Synei- 

 Itais Fr. et Sav). Aug. 1903, Mt. Komagadake in Prov. Kai (K. Tamura). 



It is quite different from P. Tranzschtlii Diet on Cacalia hastata and 

 also from any Puccinia on Senecio. 



Puccinia Benkei Kusano. n. sp. 



Teleutosori mostly hypohpyllous, arranged centrifugally, forming large 

 roundish spots 6-8 mm. in diameter, prominent, round, compact, black, 

 rarely epiphyllous in the central portion of spots; spores elliptical or oblong, 

 equally rounded at both ends, very slightly constricted at the septum, wall 

 somewhat thickened at the apex, smooth, light brown, 30-40 x 18-22 p. ; 

 pedicel persistent, long, thick-walled, slender, hyaline or pale, 140 p. 



On the leaves of Sedum Telephium L. var. purpureum Mats. Sept. 

 2. 1904, Nikko (S. Kusano). 



It is easily distinguished from P. Sedi Koern on Sedum by its 

 teleutospores. It approaches to P. exanthematica Mac Owan on Crassula 

 in its whole aspect, but differs from the latter by having much larger 

 spores with longer pedicels. 



Spores germinate as soon as they mature, so that the fungus belongs 

 to Xjeptoptcccinia.
