A second fungus of some interest is an Uredine that was found in 
considerable quantity on Glerodendron inerme. This the writer has 
met with, always producing the same characteristic effects on this 
Glerodendron, in South Andaman, Little Andaman, and Car Nicobar, as 
well as on Great Coco. The specimens were examined by the late Dr. 
Barclay, but were found insufficient for determination.

A third fungus of note causes a “ dry-rot ” in the fallen trunks of 
Mimtisops littoralis on the beaeh. The effect produced simulates in a 
wonderful manner charring by fire; it appears to be confined, so far as 
the drift timber and wreckage on these islands is concerned, to Mimusops 
and Quercus —the planks of a wooden vessel, apparently of oak, that had 
been wrecked on Little Coco, being attacked like the Bullet-wood trees; 
Teak, Sundiu and other logs were not affected.
