These specimens were found growing out of the ground, but when 
dug out carefully each was found to arise from a small, smooth, more or 
8 potato-shaped piece of wood, simulating a sclerotium. The 
ood is permeated by mycelium, and bounded externally by a thin 
datk layer, forming a delicate crust. The structure is exactly com- 
parable with that described by Petch for the pseudosclerotia of L. 
infundibuliformis and L. similis. The pseudosclerotia in this case 
age evidence of injury by termites. The dark limiting layer 
wever, continuous over the surface; hence it would appear 
dither ‘that this dark layer is formed after the wood has been partially 
eaten away by the white ants, or that the fungus mycelium is un- 
copa to them and is left uninjured when the rest of the wood is 
destroye

This fungus is fairly common on wooden pier-piles along the sea 
front. It grows only a short distance above the surface of the water.

This is the red-fieshed species which is common in the eastern 
Tropics, but the description given by Léveillé is poor and misleading. 
It does not appear to have been recorded previously for Africa.
