Survival of airborne Stachybotrys spores

Viable spores of Stachybotrys atra are rarely encountered in samples of indoor 
air.  If they are detected, the accepted interpretation, in the context of 
indoor air quality,  is that there must be (and usually is) an active growth 
site nearby as the spores do not survive for long once airborne.

Given this limited survival of airborne spores, what is the source of 
infection which will initiate growth of Stachybotrys on, say, wallboard 
which has become wet, in an otherwise dry, reasonably maintained building?

Any thoughts?
