Hi Jasper, I'd be fairly relaxed about it; there is also a thread on UKTC
some years back about it where a member posted that they'd be harvesting the
fruit bodies from a pine over a number of years; and were not very concerned
re its stability - the tree that is - can't remember which spp of pine, though

Ps I took a copy of some of the correspondence back then and kept it on my
'bits off UKTC' folder - an ideal resource for CPD! - see below, though I'm
not sure if it was the same thread as referred to above - dated 29/9/2008:
"Sparassis Crispa
Hi Dom,
In my opinion, if the Pine has Sparassis appearing all over the place then
the tree's not worth trying to retain. Mattheck, Schearze and Strouts and
Winter make little reference to it. Lonsdale considers it somewhat
negligable. However, it enters through damaged roots and causes a brown rot
of the heart wood of both stem and roots and, can extend up up into the stem
for over a metre. Lonsdale says it doesn't necessarilly lead to catasrophic
failure, but the trees are usually in dcline for other reasons.
Very often it is accompanied by Phaeolus. I would say its not worth further
invetigation, as its habit is known and the trees condition won't improve.
Ron.
It wasn't my question Ron - but I'm inclined to agree, I've only seen it on
trees I had to condemn. Once saw it associated with a 'T' shaped crack, the
external ribs of which were obscured by the mile thick Mo pine bark, with
decay in the crack extending up to 3-4m. The crack was the problem rather
than the decay though.

There is a very large 30m Specimen Monterey Pine located in the formal garden
at Saltram House (NT) property on the outskirts of Plymouth, which has had
the disease for around 6 years that I'm aware of, the sporophore/fruiting
body appears at the base of the main stem/root crown area only, or at least
it did the last time I looked at it around two years ago now.
The tree is in a very exposed location and was not showing any signs of
decline, apart from the usual small amounts of minor dead wood throughout the
crown.

I regularly go back to a very large Douglas Fir to pick S. crispa for supper
although last week the slugs had got there first. I've been picking it more
than 10 years now from this tree. The tree is near a highway (on County owned
land) so I assume it obviously gets regularly inspected, but there are still
no obvious signs of decline/ dieback etc.
best regards,
Bill

Dear collective,
Does anyone have experience of observing Cauliflower fungus on Scots pine
over a number of years or even better have tomograms or resistance drilling
measurements they can share (confidentially of course)?
I can think of maybe 3-4 previous times where I have formally recorded this
particular fungi over a 30 year period and the circumstances did not warrant
any further investigation. However, yesterday I recorded one on a huge Scots
pine (d: 116cm & h: 28m), which is within falling distance of two roads and a
house. The foliage/needle density appeared to be slightly thinning compared
to a neighbouring Scotty. Also, I was somewhat surprised to see the fruiting
mass at this time of year.
I'm sure there will be others out there who have a better understanding of
this fungi than me and I'd be really grateful for any shared experiences from
the forum.
Many thanks in advance.
