USTILAGINE.^: AND UREDINE^ OF CEYLON. 243 



studded Avith close-set large warts. Pseudoperidial cells 

 irregularly pentagonal or hexagonal, 30-36 X 16-22[jl, covered 

 with close -set coarse warts, often arranged in transverse rows 

 or confluent in irregular ridges. 



[^cidium Pavettae Berk. 



There is no specimen of this at Kew, the British Museum, or 

 Peradeniya. From the description it is by no means clear 

 that it was an iEcidium.] 



^cidium ? iquitosense P. Henn. ' 



On leaves of Psychotria elongata Hk. f ., Hakgala, May, 1910. 



iEcidia amphigenous, on pale green blistered or swollen 

 spots up to 3 mm. diameter, convex above, which become 

 hard galls when old. ^9^cidia white, tubular, becoming funnel- 

 shaped, • 15-0 • 2 mm. diameter, up to • 2 mm. high ; pseudo- 

 peridium well developed, white ; spores in mass, very pale 

 yellow. iEcidiospores irregularly ovoid, hyaline, thin-walled, 

 minutely and closely verrucose, 25-34 x 17-22^. Pseudo- 

 peridial cells usually elongated, polygonal, thick- walled, 

 verrucose, with close-set warts and ridges, 34-36 X 14-18^. 



^cidium ? VernoniaB P. Henn. 



On leaves of Vernonia Hooker iana Arn., Peradeniya, May, 

 1910. 



Spots pale yellow-green, often extending over the whole leaf . 

 iEcidia usually hypophyllous , rarely one or two on the upper 

 surface, crowded, not concentrically arranged, 0*25-0 "5 mm. 

 diameter, pseudoperidium strongty developed, stout, recurv^ed, 

 white, mass of spores yellow. ^Ecidiospores ovoid, 18-21 X 

 13-15[jL, or globose, 16-21j;. diameter ; wall hyaline, closely 

 and minutely verrucose ; contents yellow. Pseudoperidial 

 cells pentagonal or quadrangular, 18-31 X 15-25^, verrucose, 

 with large close-set warts and ridges ; wall up to 4[x 

 thick. 



The spores are smaller than those of ^c. tarapotense P. 

 Henn., but larger than those of ^c. Vernonice, according to 

 the descriptions of those species, and the latter is said to be 

 epiphyllous.
