USTILAGINE^ AND UREDINE.E OF CEYLON. 225 



globose, 5-7 {ji, diameter. 8pores of the Ceylon species are pale 

 olive, ellipsoid, coarsely warted with dark warts, 5-9 x 4-6(x 

 (Kew specimens) ; ellipsoid, 5-11 x 4-6^, or globose, 5-7[x 

 (Peradeniya herbarium) ; 5-11 X 4r-l<^, or globose, 4-7 jjl 

 diameter (fresh specimens, Ceylon). The spores of the fresh 

 specimens are darker than those in the herbarium. The 

 filaments in the Ceylon species are greenish olive, up to 40 ^ 

 diameter and several millimetres in length, composed of 

 numerous parallel hyphae. It would appear that the Ceylon 

 species is identical with Ustilago olivacea (DC.) Tul. 



Ustilago digitariae (Kze.) Rabh. 



On Panicum repens L., Bandarawela, April, 1908 ; Hakgala, 

 October, 1908 ; Haputale, March, 1912. 



Ustilago anthistiriae Fetch. 



In ovaries of Anthistiria- tremtda Nees, Peradeniya, May, 

 1908. 



Ustilago tonglinensis Tracy & Earle. 



On Ischoemum ciliare Retz., Peradeniya, April, 1907, &c. ; 

 Bandarawela, April, 1908. In the ovaries, or converting the 

 whole inflorescence into a black mass, surrounded by a thin 

 white membrane. Spores ll-lSfx, blackish olive, rough, with 

 close-set warts. 



Ustilago spermoidea B. & Br. 



In the ovaries of Citronella grass (Lena batu), February, 

 1908, leg. J. F. Jowitt. Andropogon nardus L., Bandarawela, 

 March, 1908 ; Hakgala, April, 1907. Andropogon venustus 

 Thw., Peradeniya, May, 1908. 



This species was originally recorded by Berkeley and Broome 

 as " On Cymhopogon Martii." The herbarium specimen at 

 Peradeniya is marked Cymbopogon Martini, which, as imder- 

 stood by Thwaites, is a synonym of Andropogon nardus. 

 Spores subglobose, almost smooth, 7-10^^. It would 

 seem probable that Ustilago nardi Syd. & Butl. is the same 

 species.
