Bill (Oct 7),

*Washingtonia robusta* or "Mexican fan palm." The ivy survives only under
irrigation. This one is near the coast where the humidity is frequently
higher than inland.

Scrolling through the subsequent years reveals that the tree doesn't seem

So the two plants seem to be co-existing? What is the Palm? Not that I've
got any familiarity with anything beyond the Cabbage Palm (Cordyline
australis). I'm sort of surprised that the Ivy is surviving the southern
Californian climate.....

Ah, my prejudices with respect to my UK colleagues is now reinforced:

I quite agree with most of what Ross and Brewster have said, and share
some
of the same questions.

I might add that most trees resist the invasion of parasitic pathogens
*unless* there is an opening in the protective inner bark layer. I should
be delighted to stand corrected by any evidence that saprophytes do not
affect the outer bark of some species.

Here in the US it is true that "our" indigenous species did not co-evolve
with ivy. Here in the rather drier Southwestern US, ivy invasions are
commonly restricted to the more mesic habitats, particularly those that
supply supplemental water (e.g. sprinkler systems) in landscaping.
Algerian
ivy is perhaps more common than English ivy in some areas. Here is a link
to a GSV photo taken near 4736 Voltaire St. in San Diego, CA, USA:

Subject: Re: Fungus on Lime - Ivy

Firstly, Ivy is an introduced species to America and like so many
introductions, causes problems that it doesn't cause in habitats where
it has evolved with other species that have a tendency to control or at
least limit its growth, or else live amicably with it.
Secondly, one of the ways trees manage to live amicably with it is (for
deciduous trees anyway) by limiting its capacity top grow and spread
through the summer by producing dense canopies, so the ivy is happy
enough climbing up the trunk, doing much of its photosynthesising (and
of course its fruiting)  in the winter months. It's only when the ivy
becomes more vigorous than the host tree, that is when the host is
losing vigour and beginning to decline, that the ivy can become a
problem by proliferating and spreading out onto the lateral branches
where it can start to smother the host's foliage. (It can be more
problematic on evergreens such as hollies and yew, as it has to grow
straight to the outside or tops of the tree to order to seek light,
with
the result that it tends to suppress and smother the host tree at an
earlier stage.
SO... I suggest that ivy is not an cause of decline but a symptom,
albeit one which may exacerbate the situation.

That's my theory anyway.

Dear All,

Coniophora puteana, a well-known cause of wet-rot in timber, can
degrade
the outer layers of the bark of various tree species if humidity is
high
(typically near ground level). The underlying inner bark remains intact
and
eventually becomes exposed by the shedding of the decaying outer bark.
The
exposed inner bark usually looks smoother than the surrounding
unaffected
outer bark; hence the name 'smooth patch' for this condition.

Ivy tends to promote and maintain a higher humidity in such
micro-environments, so perhaps its removal might discourage fungal
development. Closer examination might reveal useful particulars.
Sometimes
saprophytes consume the bark, setting up conditions for entry into the
heartwood, as well as set up conditions for parasitic species. Even
loss
of
heartwood weakens the tree, which can appear to the casual observer to
be
"perfectly healthy."

I am speaking from experience in the USA only. Even in the relatively
dry climate in which I live now, I have observed such phenomena in
association with ivy. Some species appear to be more tolerant than
others.
In susceptible species, failure is often the result, even of those
"perfectly healthy" ones. Any tree professional should perform all of
the
necessary investigations to secure as complete as possible analysis.
(No
offence to my UK listserv pals, but failure to follow those procedures
seems to be more common than not here in the USA.)

In susceptible species, failure is often the result, even of those
"perfectly healthy" ones. Any tree professional should perform all of
the
necessary investigations to secure as complete as possible analysis.
(No
offence to my UK listserv pals, but failure to follow those procedures
seems to be more common than not here in the USA.)

Subject: Fungus on Lime

I think this is some form of dry rot - do you agree? It was growing
on
two Lime trees under ivy. I didn't find any bark necrosis, though
one
tree has a small amount of sapwood delignification (possibly
unrelated). Does anyone know the effects of this on trees?
