HEART-ROT CAUSED BY OTHER FUNGI 148 
Note.—Since writing the above I have found a larch near 
Oxford in which part of the crown is heart-rotted, apparently 
by this fungus. The rot had not advanced very far and no 
fructifications were present. The rotted portion shows 
incipient ring-shake through the partial decomposition of 
the junctions of the annual rings. The holes described at 
the junctions occur chiefly in the last-formed elements of 
the summer wood, but the first-formed spring wood of the 
next year is in places affected. In each annual ring there 
is also a number of radially extended delignified patches 
and holes. The rotted portion, which occupies the centre 
of the stem, is surrounded by a layer of insoluble gum 
which resembles that described in connexion with Fomes 
annosus. Photographs of the specimen are shown in figs. 
56 and 57.
