Hi all,

We've been having an issue in the bathroom recently where some sort of
pale yellow growth appears from the edge of the floor, if you spray
mould removing spray on it, it turns dark red like this picture shows:

http://i363.photobucket.com/albums/o...ndom/photo.jpg

.... and shrinks a bit.

The above picture is a bit of an extreme example as it had been allowed
to develop as we were away for a few days.

Can anyone confirm what it is and how to get rid of it and stop it
happening again? The bathroom has an extractor fan which works, trickle
vent on the window and a gap under the door. The window is usually left
open in all but the coolest weather (and when the shower is in use).

Thank you

It looks suspiciously like some kind of wood rot. I suggest you get
expert advice on which sort it is and the right treatment. I am no
expert but it looks to me a bit like dry rot (a neighbour had it).

That looks like a fungus of some sort, is it a leathery sort of growth?

Well the room is well ventilated but what is behind that red panel under the
floor or skirting? Fungus/molds generally like permenant damp, so you need to
find the source of that damp. Hidden leaking pipe, leaking window/window
frame, water on the floor not mopped up and getting behind those bits?

Behind the red tiles is where the soil pipe from the toilet goes; the
toilet sits right in front of the red tiling box, further down is the
sink and the hot and cold water pipes come up from inside the red tiling
box and up to the sink. There is no window on that wall. I think some
further investigation is required, do you think it is worth lifting up
the lino flooring first to see if it's from the floor and then break up
those red tiles?

That is some sort of fungus/rot. The bit you see there is the fruiting
bit that disperses millions of spores.

You need to fix this pronto. Get the floor covering up, floorboards
and skirting off.
If you don't you will shortly have VERY serious problems.

May already have. DON'T DELAY.

You need to replace all rotted timber and treat the whole area with
rot killer. All timber, brickwork the lot.

Once established, dry rot (which I think it is) spreads like wildfire
and needs no further moisture.

As others have said, it is the fruiting body of a fungus, probably one
of the dry rot types. This will be just the tip of the iceberg, and
there will probably be a large area behind the bulkhead affected by rot.

If you're *very* lucky, it won't have affected the floor structure yet
(Assuming it's a wooden floor), but it can affect nearby wood, even on
the other side of a wall. The normal method of removal is to remove and
replace *all* wood within two or theree metres and treat the rest. While
you're at it, you'll need to improve the local ventilation behind the panel.

Tciao for Now!

From the description, it sounds like fungal growth. its probably one of
those that is often called dry rot. the eventual fate of any wood seems to
be kind of seperated sinews and dust.
Not nice.

If it is fungal, you will only be seeing about ten percent of it, ie the
parts that spread the spores, its probably quite extensive in the underlying
material.

Important to sort it out now not later. Remove any floorcoverings in
the way to see whats going on and remove infected material. This is
the price of lino on wood floors.

Thanks everyone, we have stripped the lino back and there isn't any sort
of growth underneath, the wood floor seems to be slightly damp on the
surface so we have left it without the lino to allow it to dry out and
see if anything happens after this.

It's Serpula lacrimans, IE dry rot, and the fact that you've seen the
fruiting body, means that it's already well established.

The dry rot won't be visible on the surface of the floorboards, but when you
take them up, you'll see white 'roots' growing in every direction, over the
underside of the floorboards, joists, backs of skirtings and architraves,
door frames etc, and the longer you wait, the further it's spreading.
If this is a downstairs bathroom, the rot will be spreading to the first
floor joists and upwards (it can go through and along brickwork joints for
several metres without the requirement of timber) if it's a 1st floor
bathroom, the rot will be spreading both upwards and downwards.

It starts off in wet timber but soon spreads to normal, dry timber and
leaves it totally dried out and cracked - it resembles a crocodiles back,
like a cubic pattern, and you can poke a finger straight through what was
originally a 8 X 3 timber joist.

You need to get those boards up and see what's beneath. And the
skirting off.
This could be a very serious problem.

It is the sort of thing that you really need to get specialists in to
deal with if you want any kind of guarantee. They can use far more
aggressive chemicals than are available to DIYers.

Basically though it is physical removal of large amounts of affected
wood, plaster and possibly even bricks to zap every last trace and then
powerful chemical antifungals. ISTR they come with a 25 year guarantee.

The neighbour ended up with their entire ground floor ripped out and
replaced. Everything under the floor had a layer of mycelium on it. They
only realised there was a problem when the fruiting bodies appeared. It
appears that putting down parque flooring had trapped enough moisture in
the wood to allow the rot to get a foothold.

The dry rot won't be visible on the surface of the floorboards, but when you
take them up, you'll see white 'roots' growing in every direction, over the

Yes. It is scary stuff and not something you want to leave untreated.
Question is where did it get started ?

Not as bad as one place I was intending to buy until I walked through
the door, and saw a layer of rot spores on the floor. So I quickly
walked out again, and made sure my shoes got thoroughly cleaned before I
got into the car to drive home.

where this fruiting was seen/

No idea tbh, will have to do some further investigation on the wall
outside where the soil pipe and other waste water pipes are. A very long
time ago, probably 15-18 years now, we had some sort of problem in a
room downstairs, think it was wood worm or something. The whole floor
was replaced then! Still have the certificate to show it had been I think.

Well, had someone in today (I was at college) but from what mum told me,
he said it's not dry or wet rot; there is usually a distinct smell from
dry or wet rot. He gave some sort of latin name and said it's some sort
of fungus I think? The advise he gave was to remove the floorboards,
find the source of moisture and fix that, let the floor dry very
thoroughly and then give it a coat of some chemical available from B&Q,
don't remember what it was. He said if left, it could become worse...

Oh dear, well this thread needed updating anyway, the cause of moisture
is a leaky pipe just under the floor, the water has been shut off
temporarily to that area while the floor dries out. The pipe supplies
the small toilet just next door to the bathroom
