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:

.... 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
