USTILAGINE^ AND UREDINEiE OF CEYLON. 239 



Ravenelia Breyniae Syd. 



On leaves of Breynia patens Hk. f., Hakgala, March, 1907, 

 May, 1910 ; Haputale, March, 1912. 



A bush at Peradeniya has for some years borne a Uredo 

 whose spores appear identical with those found among the 

 teleutospores of the Hakgala specimens, but no Ravenelia has 

 yet been found on it. These uredo-sori are amphigenous, 

 either scattered, or clustered on pale yellow spots up to 2 mm. 

 diameter, about 0*25 mm. diameter, circular, pale yellow, 

 almost white. Spores oval or globose, almost hyaline, spinu- 

 lose, 19-27 X 18-21[jL. Paraphyses up to IOO^a long, slightly 

 inflated upwards, 8^ diameter at the apex, which is sometimes 

 sUghtly capitate ; wall thickened at the apex. 



Ravenelia macrocystis B. & Br. 



o This was described by Berkeley and Broome as follows : — 

 'Pseudosporis e celluhs paucis magnis compactis e myceUo 

 radiante .oriundis (No. 515). On Cassia Tora, Damboul, 

 March, 1868. Spores -0015 (inches)." 



Cooke (Joum. Roy. Microsc. Soc, XI., p. 387) stated that he 

 had not seen a specimen. Dietel (Monographic der Gattung 

 Ravenelia) states that specimens sent him from Kew did not 

 show any of the fungus. The specimens at Kew from Herb. 

 Berkeley and Herb. Cooke exhibit several patches of the 

 fungus along the pieces of stem or along the veins of the leaves. 

 Numerous circular black bodies, which to some extent resemble 

 Ravenelia spores and correspond with Berkeley and Broome's 

 figure, are crowded together, but they are seated upon a 

 superficial myceHum which scales off when touched with a 

 needle. The mycelium is fuscous and furnished with appres- 

 soria. From the various stages of these spore -like bodies, it 

 is evident that they are the developing perithecia of a Meliola, 

 or some allied species.
