Now the problem! Yesterday I was on safari at the far reaches of our
garden (about 30 yards from the house!) and noticed one of these large
chunks of wood had fungus on it. A very spectacular layered fungus
(pic on request). Actually this piece had rolled away and disappeared
under a holly bush which is why I hadn't seen it before. Now it is
nearly always wet under there. Anyway I looked up the type of fungus
and it looks to me like DRY ROT!!!

If you don't know you fungi, then many species "look like" dry rot.


I've seen what dry rot can do to a house and it doesn't appeal to me
very much.

Just so.

Dry rot spores are *everywhere*, so if your house might be
susceptible to dry rot then it will get dry rot! The only
solution is to (1) ensure the house won't support dry rot by
either dousing everything in seriously noxious chemicals
or by (2) ensuring the conditions are wrong for the mycelium,
to grow.

(2) is obviously preferable, and only use (1) if you've
actually got an infestation.
