of mycelium described above. The branches are eventually killed 
vessels of the wood by mycelium. So far as can be observed 
from an examination of the ample supply of material forwarded 
by Dr. Watt, the fruit of the fungus is only produced after the 
branch on which it occurs is dead, when it appears on the surface 
of the bark under the form of miniature pins about half a line 
high, and of a pale yellow colour. These fruits generally occur 
in large numbers, giving to the branch a minutely velvety or hairy 
appearance as seen with the naked eye. 
In the absence of living material it is impossible to state 
interior of the living plant; but the general habit suggests the 
idea of its being a root-fungus, first attacking the slender — 
and afterwards extending into the above-ground portions of t 
plant. If mycelium is found in quantity on the thicker vit 
branches and about the base of the trunk, the above supposition 
would doubtless be correct, and would imply the presence of 
strands of mycelium in the soil ; such strands pete traversing 
the soil and extending from one plant to another, as is known to 
the case in other root-parasites, as Dematophor 4 pi atrix and 
Rosellinia radiciperda. The fungus described above is in all 
probability o nly the conidial ess of some higher form, which, 
as is usually the case, nese forms its fruit on igs a "decay ed
