Re: mushroom type growth - help!
Check to see if there are spider weblike offshoots to them. Make very sure this is not dry rot!!! This occurs when wood has gotten wet and gone unnoticed, later when heating etc. is put on the fungus starts to grow!! We've had dry rot and it doesn't only affect wood, it goes into the plaster and even brick! The first sign is usually paint bubbling, or the plaster crumbling. It can be very serious and spreads rapidy. Hopefully you don't have it...there is another thread on it, I know, cos I started it and got some good advice.
