32 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. 
Of the several kinds of larvee which are to be found affecting 
different parts of the oak tree, I have never found any in the acorn, 
nor do I find any record of such. This is to be noted, as very few 
seeds of plants escape the ravages of some variety of insect or 
another. 
Fungi. 
We now come to treat of the fungi that are to be found on the 
oak, but it is doubtful whether they can be properly classed as a 
disease, or only as the result of some other disease or of natural 
decay, for whenever they occur it is a certain sign of the bad 
condition of the tree. 
Some tree fungi are not particular as to the tree upon which 
they grow, whilst others confine themselves to one genus or species. 
The following may be taken as an approximate list of those 
found on different parts of the oak, some of which are to be found 
on other trees and substances :— 
Galarileus quietus, in oak woods. 
Pleurotus dryinus, on the tree. 
ie palmatus, on the tree. 
Crepidotus aurant ferrugt, on the roots. 
Coprinarius papyraceus, on the tree. 
Dedalea quercina, on the tree. 
Microporus frondosus, on the roots. 
3 sulphureus, on the tree. 
x hispidus, on the tree. 
Fistulina hepatica, liver-like or beef-steak fungus, grows 
on old trees in the New, Sherwood, and Epping 
forests, and is edible. 
Hydnum minimum, on the rotten timber. 
erinaceus, hedgehog fungus, is very rare and 
curious. Found in Epping Forest, and recently in the 
New Forest, by Dr M. C. Cooke, the eminent myco- 
logist.
