Ustilaginoidea Penniseti sp. nov. 



Attacked glumes become swelled, several times larger than 

 common one, black ; sclerotium spherical, dark— black, densely 

 verrucose, 22-28 in diameter. 



On Pennisetum compressum R. Br. (Shinchou, Hunan ; Oct. 

 14, 1908). 



According to Saccardo's Sjlloge Fungorum, we have five 

 species Ustilaginoidea, that is JJ. vierens Tak., U. Setarise 

 Bref., U. mossambicensis P. Henn., U. ochracea P. Henn. and 

 U. usamhariensis P. Henn., but my species is quite different in 

 its colour from the former two and in its size of scleotium, 

 from the others. 



Phyllachora graminis Fckl. Sacc, Syll. H. p. 602 et IX. 

 p. 1026 ; SoRAUER, Pflzkr. H. p. 222 ; Engler, Pflzfam. I. I. p.

On Miscanthes sinensis Aud. (prov. lichang, Hupei ; Sept. 

 25. 1908). 



Melanomma glumarum Miyake. Miyake, in Journal Col- 

 lege Agric. Tokyo, 2 (1910) Tafel 13 fig. 1-3. 



On Oryza sativa L. (Soochou, Kiangsoo ; Nov. 1908). 



According to Mr. K. Hara, this fungus was very common 

 in the vicinity of Tokyo and paraphyses which in my descrip- 

 tion are not mentioned, exist also. When I got it for the first 

 time in Soochou it was nearly the end of the harvest season, 

 therefore my materials were scarcely enough to determine its 

 characteristics and for this reason my observations are imper- 

 fect. I am grateful to Mr. K. Hara for supplying to me these 

 details which I was unable to get from personal observation. 



Mycosphaerella Fomacearum Sacc. Sacc, Syll. I. p. 482. 



On Pirus Malus L. (Peking; Oct. 1910). 



This fungus appears together with certain conidiaform, 

 Phvllosticta, Coniotliyrium and Hendersonia in one spot, but 

 not with Septoria, Diplodia, etc. as in Saccardo's Sylloge 

 Fungorum. In spite of the differences of conidiaform I put the 

 present species under this name because the ascoform is the 

 same in both and those conidiaforms naturally are very closelj- 

 related.
