oot. Its weight is estimated at 1,400 kg., and the root concerned is only 30 cm. in
thickest diameter. “An instance is also known in which a stone of 160 kg. (352 lb.)
was raised and shifted by the growing fructification of a fungus of the mushroom
tribe” (p. 514).
Other trees are quoted, but they all dwarf into insignificance in their effects as
compared with the devastation caused by tropical Figs (Ficus). I have no
illustrations of Eucalypts, but observers have often noticed what great disruptive
force they are capable of exercising.
Epiphytes.
One of the most charming sights I have ever seen was that of huge masses of
Dendrobium aemulum R.Br., flowering on the trunks of E. paniculata at Wyong,
N.S.W.
Cymbidium canaliculatum R.Br., is epiphytal on spp. of Eucalyptus in New South
Wales, but especially on E. clavigera A. Cunn. in N. W. Australia (W. V.
Fitzgerald). It is common on Box trees, resting in the forks. These epiphytes do not
injure the trees, so far as I know. The subject of epiphytes on our Eucalypts may
well be taken up by an observer.
(c) Fungi.
I am much indebted to Mr. Edwin Cheel, my chief Botanical Assistant, who has
favoured me with the following valuable list and notes of fungi recorded as having
been found on various species of Eucalyptus. Unfortunately, the particular Eucalypt
is not mentioned in very many cases. It is obvious that there is still a wide field of
research indicated by Mr. Cheel.
The list includes 113 species, representing 31 families and 71 genera of fungi,
found on 35 species of Eucalyptus. Cooke and Harkness (2) have recorded 42
species, representing 32 genera, found on E. globulus cultivated in California.
Thumen has also recorded a species of Eucalyptus cultivated in Portugal. Six
species of those enumerated in Cooke and Harkness (2) have also been definitely
recorded as having been found in Australia, and are accordingly included in the list
herewith.
It is interesting to note that of the 35 species of Eucalyptus specifically mentioned,
E. globulus is the host of the largest number of species of fungi in Australia, as well
as in California, 12 species having been actually recorded on this host. This is
owing to the circumstance that this species was for many years the commonest
species cultivated abroad. E. viminalis comes next with 7 species and E. amygdalina
with 4. The various species of Polyporaceae are the most numerous and worst foes
of Eucalypts, as they attack the living trees as well as the dead wood. Even fencerails
and building material after it has been dressed is frequently attacked by the
