Trichothecene producing molds that grow under low humidity?

[Guest guest]

What trichothecene producing molds can grow (not necessarily visibly)

under normal humidity levels, and if there was no flooding, moisture

problems etc?

Stachy requires a lot of water for a prolonged time, so it's out of

the question. Other molds that produce trichothecenes are Fusarium,

Trichoderma, Trichothecium, Myrothecium, Cephalosporium,

Cyclindrocarpen, Verticimonosporium and Calonectria.

For instance I have had papers, and wooden furniture that got

cross-contaminated with this mold (whose identity I'm still not sure

about) under completely normal humidity levels - no excessive

humidity. There has never been visible mold growth though, but I can

sense its presence easily. Sometimes borax can significantly alleviate

the problem. Sometimes I must apply H2O2 to deal with mycotoxins.

Since borax does have effect on this mold, and it is not known to

decompose mycotoxins, it follows that this mold is still alive. So

what can it be?
