I think they are just playing a numbers game...innoculating with way
more colony forming uints of the competative fungus than were present
for the wild, toxin producing fungus.

the factor that supports the outcompetition?  Both are the same fungi
but different strains.  The only logged difference seems to be the
production of aflatoxins.  So why would a fungus that doesn't produce
aflatoxins be dominant in an environment where both should grow?  Why
does the nontoxin producing fungus outcompete the toxin producing
parent?
