Mclanospora chry Somalia B. & Br., Fungi of Ceylon, 

 No. 1125, Joum. Linn. Soc, XIV., p. 130. 



Perithecia scattered or gregarious, superficial, each in a 

 yellow globose tuft of hyphse by which it is attached to 

 the substratum. Perithecia black, globose, 0-4 to 0*5 mm. 

 diameter, clothed with coarse, intertwined, irregular yellow 

 hyphge, 4 jj- diameter, with a black cylmdrical ostiolum, 0-4 

 mm. high, 0-1 mm. diameter. Outer layer of the perithecium 

 wall fuscou^, inner layers thick and yellow : wall fleshy, not 

 carbonaceous. 



Asci cylindrical with a short abrupt pedicel, 85-90 X 8 ft ; 

 spores obliquely uniseriate, or linear in the lower half of the 

 ascus ; spores 12-13 x 6/^, fuliginous, oval, with three cross 

 septa and a longitudinal, sometimes oblique, septum in one 

 or both of the two middle loculi ; not constricted at the septa ; 

 the septa appear thicker than the wall. Paraphrases absent. 



The peritliecia are accompanied by pycnidia surrounded by 

 similar yellow liyphse, and with walls of the same texture as 

 those of Bivonella chrysomella. Pycnidia black, somewhat 

 conical, 240 fi high, 200 /jl diameter ; mouth fimbriate with 

 yellow hyphse : basidia simple, 12-16 x 1-2 t*, or acutely 

 branched with branches up to 25 M long ; sporulge liyaline, 

 3 X 1-5 /u, oval. 



Specimens recently collected on decaying bamboo, at 

 Peradeniya, agree exactly with Berkeley and Broome's type 

 specimens in Herb. Peradeniya.
