showed that the mycelium of the Polyporus was growing partly on the wood and partly over the Tiger's Milk and there was not only no mingling of the two bodies, but their microscopic structure was totally different. In that of the Polyporus there were no round globose cells, but a mere mass of mycelium threads as in an ordinary Sclerotium, 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.
