USTILAGINE^E AND TJREDINE^ OF CEYLON. 247 



Apparently Mcidium luculentum Syd. from Mysore differs 

 in having pseudoperidia immersed, pseudoperidial spores 

 larger (50-70 X 28-40^) and secidiospores larger (38-52 x 

 26-35\k), but in other points the two species agree. It may 

 be noted that the character of an ^cidium , whether immersed 

 or columnar, depends to some extent on the state in which the 

 specimen is collected, or, when dried specimens are examined, 

 on the treatment to which the specimens have been subjected ; 

 it may also vary normally, as in Mcidium rhytismoideum Berk., 

 some specimens of which have immersed secidia, while others 

 have columnar secidia up to 0*5 mm. long when gathered. 



Mcidium bulbifaciens was said to grow on stems, but there 

 is no reason to suppose that it is confined to that position. Of 

 the remaining species recorded on Loranihus, Mc. Cookeanum 

 de Toni does not exhibit galls, but the specimens are apparently 

 on immature leaves. Mcidium goyazense P. Henn. differs in 

 having smooth spores and secidia up to 5 mm. high (? correct). 

 Mcidium Loranthi Thumen has " cupuhform " aecidia, and 

 spores 30-36[ji. diameter. The Ceylon species appears nearest 

 to Mcidium bulbifaciens, but the descriptions suggest that a 

 re-examination of the types might establish the identity of 

 at least all the South American species. 



Uredo Pers. 

 Uredo uguressee Petch. 



On unripe fruits of Uguressa {Flacourtia ramontchi Sher.), 

 Galle, July, 1907. On leaves of Flacourtia sp., Peradeniya, 

 December, 1910, leg. E. E. Green, January, 1912. 



Uredo gossypii Lagh. 



On leaves and bracts of Gossypium spp., Peradeniya, June, 

 1905, July, 1909. This is identical wdth Mcidium. desmium. 

 B. & Br., Fungi of Ceylon, No. 850, collected at Peradeniya, 

 January, 1868. The name must therefore stand as Uredo 

 desmium (B. & Br.). 



Uredo bombaeis n. sp. 



On leaves of Bombax malabaricum DC, Peradeniya, 

 December, 1911. 



No evident spots. Sori minute, on the under surface of the 

 leaf , orange , up to • 2 mm . diameter , clustered . Uredospores
