23, 1913, on leaves of Dunbaria sp. 
The present species appears to be best referable to Sydow’s genus 
Pwzschkeella described from Brazilian material in Bull. Herb. Boiss. II 
1 (1901) 83. The Philippine specimen differs in several respects from 
the original description and a comparison with Sydow’s type might show 
that our plant should be better described as the type of a new genus.
