344 ON THE SO-CALLED TIGER’S MILK. 
showed that the mycelium of the Polyporus was growing 
partly on the wood and partly overthe Tiger's Milk and there 
was not only no mingling of the two bodies, but their 
m croscopic structure was totally different. In that of the 
Polyporus there were no round globose ceils, but a mere mass 
of mycelium threads as in an ordinary Scierotium, so that the 
growth of the Polyporus upon the Susu Rimau is a mere 
accident, and we have again to seek for the fungus which 
produces this Tiger’s Milk. 
The plant is evidently not a very rare one and is well known 
to the Malays, so that if some of those whose business leads 
them into the jungles of the Peninsula will make enquiries 
about it, we may hope ere long to obtain the fungus it pro- 
duces and settle definitely its name and life history.
