Palawan, Taytay, Merrill 8764, April, 1913. On dead spathes of Cocos 
nucifera. 
This new genus is related to Hysterostomella and Polystomella, differing 
from the former by the presence of paraphyses, and from the latter by the 
colored sporidia. The hypostroma of both species, P. grandis and P. Co- 
coes, consists of fuliginous, many septate hyphse running deeply in the 
tissue, creeping upward between the sclerenchyma bundles and forming 
thick effused balls beneath the epidermis. The hypostroma breaks through 
the stomata of the epidermis and so forms superficial ascus-bearing stro- 
mata. The latter are adnate with their whole base to the substratum. 
They are either small or more or less confluent and large, and are pluris- 
tratose like the shell of an oyster so that the center is very thick and 
carbonaceous. The margin is entire or very slightly crenate in P. Cocoes, 
and sometimes more fimbriate-dentate in P. grandis. The loculi have no 
ostioles, but the covering stratum is finally cracked and a round opening 
formed over them. The ripe sporidia are somewhat longitudinally plicate 
in P. Cocoes.
