Ceratoystis-Ophiostoma group is considered common lumberyard and is often found in commercial lumber or in a living tree as a pathogen.
There is NO surrounding water damage to adjacent wood. This is a major indication this is common lumberyard mold.
It is spread as a wet spore by insects.
This mold generally originates from wood framing inside walls.
Allergenicity has not been studied. Persons most likely to be possibly infected are lumber-yard workers or carpenters. A connection between Ophiostoma and the human pathogen Sporothrix schenicki has been proposed but not confirmed. Ophiostoma ulmi is the cause of Dutch Elm Disease.
- Allergen: coughing and sniffles
