upwards a short column. Tliis bifurcated at the top into two 

 sliort processes, eacli ending in a large oi^ening, the pycnidial 

 orifice. One stroma had onlj^ a terminal orifice and another 

 had three. The pycnidium is deep and somewhat lobed at the 

 base. The orifices were jalugged with yellow -brown or olive-green 

 gelatinous masses of conidia." The remains of this specimen 

 are now in Herb. Peradeniya. The stromata are pulvinate, or 

 conico-pulvinate, up to 1 mm. high, or scarcely elevated, with a 

 narrow hypothallus ; some bear one or two short processes ; 

 other.s, immatuie, bear numerous developing processes ; tlie 

 P3^cnidia occur singly in each process, or in the body of the 

 stroma ; one specimen has a large, flattened-globose pycnidium, 

 0'8 mm. diameter, and 0'3 mm. high, in the body of the stroma, 

 and .smaller (immature) pycnidia, 0'2-0*3 mm. diameter in its 

 processes. 



The colour of the spores in mass is usually pale yellow. The 

 green colouration noted by Parkin is a frequent abnormality in 

 illeyrodiieolous species of Aschersonia. 



Tlie pycnidial stromata are very variable, but, in general, they 

 may be identified by the long cylindrical neck of the pycnidium. 

 At first glance they may be mistaken for Aschersonia oxy stoma, 

 with which they sometimes occur, but they are not translucent 

 as in the latter species. The perithecial stromata include forms 

 which resemble Hypocrella convexa, others approaeliing HypocreUa 

 phyllogena, and some which resemble a group of confluent nectrias. 



This species has been found recently on A llophylus zeylanicus, 

 and on Lasianthus sp., Hakgala, Ceylon, January, 1914. 



Distribution. — Ceylon, in Herb. Peradeniya.
