British North Borneo, Tenom, Yates 10k, October 17, 1917, on leaves 
of Pterocarpus indicus. 
This species is very abundant on the leaves of Pterocarpus, associated 
with Meliola pterocarpiae Yates, The 2-celled brown spores readily dis- 
tinguish it from the other PhyUachoraceae reported upon this host. Co- 
nidia are borne on the younger stromata. They are subglobose or 
somewhat irregular in shape, brown and about 10 to 12 p diam.
