PALAWAN, Taytay, Merrill 8739, 8757, 8794, April, 1918. All on dead 
petioles and rachis of Calamus; Merrill 8808, on dead leaf-rachis of Oncos- 
perma horrida; Merrill, 8872, on dead Flagellaria indica; Merrill 8847, on 
dead stems of Drynaria quercifolia. 
We have compared the Palawan specimens with the types of Microthy-

rium grande and Seynesia calamicola, and have found that all these repre- 
sent the same fungus. Theissen, to whom we are much indebted for the 
accompanying figure of this fungus, drawn after the Palawan specimen on 
Calamus, has taken up the fungus as a doubtful Seynesia in Oesterr. Bot. 
Zeitschr. (1912) 23 extr., but because of the poor specimen seen by him at 
that time. Palawania grandis is nearly related to the following P. cocoés, 
but differs in its external appearance, and the somewhat longer and less 
septate (articles 8-15 » long) hyphae. 
The specimens growing on Calamus must be considered as typical. The 
forms growing on the other hosts mentioned seem not to differ.
