.... Easy money though if people start thinking it's the cat's meow.
For some situations is is.
When I bought the old house I've been remodeling for the past 15 years, I found some fungus that looked like Serpula Lacrymans.That scared the crap out of me, since this is the most destructive form of dry rot in buildings and if found, takes severe measures to remove/cure.
Any wood has to be cut back to at least 3 feet behind affected areas and treated with fungicides. Since I found fungal bodies in both floor substructure and roof construction, if it was S.L. the cheapest thing to do would have been to burn the house down and build a new one.
Imagine how I felt when I got the lab report ( which by the way, I paid them extra to expedite!!) saying that it was a close cousin, but not the actual SL.
The one I had is not very agressive and easily cured................whew!!
Serpula lacrymans comes from Himalaya and has supposedly been brought to England in a load of lumber, then it has spread to the rest of Europe.
In Sweden they are training dogs to find it by smell. Since you can insure your house against it, insurance companies pay the dogs ( or their owners) to check houses before insuring them.
