According to Berkeley the spores are smooth and very 

 minute ; but in the description in vSaccardo (furnished by 

 Cooke) they are said to be " subtihter rugulosis." 12-15iJ. 

 diameter. Massee states {loc. cit., pp. 402-3) that they are 

 smooth and 5-6[jl diameter, while Dietel (Engler-Prantl, 

 Pflanzenfamihen) gives them as smooth and 4jx diameter, 

 Mc Alpine (Smuts of Australia, p. 164) states that in a 

 specimen from Java examined by him the spores were globose 

 to ellipsoid, very delicately echinulate, and 7-8^ diameter, or 

 7-8 X 5-6iJL, violet-tinted. He also quotes a communication 

 from Kew to the effect that the type specimen of emodensis 

 has irregularly globose spores, violet, thick- walled, almost 

 smooth, and measuring 5-7 [i., and that it agrees with Ustilago 

 Treubii Solms (Exsicc, No. 56). 



In Ceylon the fungus forms either spherical galls in the 

 inflorescence, or clustered conical outgrowths on the stem, 

 which agree exactly with the figures of the Javan species. In 

 both situations the spores are spherical. 7-10^., with a few 

 irregularly ellipsoid, 7-10 x 5-7 ; they have a pronounced 

 violet tint, and an epispore so closely and regularly warted 

 that it appears reticulated in certain aspects. 



Ustilago Scleriae Tul. 



Recorded by Berkelej' and Broome. Fungi of Ceylon. 

 No. 841 (Thwaites 450, 459). 



Ustilago endotricha Berk. 



On Carex bengalensis Thw. (= C. indica L.), Dolosbage. 

 May, 1868 (Berkeley and Broome, No. 843). Abundant at 

 Hakgala on Car ex haccans Nees. 



All the specimens of nuloirirhn at Kew are marked (richo- 

 phora by lierkelcy, one Ceylon specimen being labelled var. 

 Thwailcsii. Bcrkelej' and Broome give the sjjores of the 

 Ceylon species 5-12*5 X 4-10(j,, and state that there are more 

 fibres than in the New Zealand species on (lahnia, from which 

 it was first described. The Ceylon species certainly is more 

 woolly, according to the Kew specimenfl, and it is olive, whereas 

 the New Zealand specimens at Kew are black. Spores of the 

 latter (Kew syjccimen) are blackish olive, minutely warted.
