By definition, no.  Aspergillus and Penicillium are two well-known 
deuteromycete genera. Some species of Aspergillus and Penicillium make 
cleistothecia with fully fertile ascospores, and some do not.  Those 
that do not, do not cause problems.  But those that do are members of 
the Deuteromycota only when they don't; and when they do, then they're 
not.  Definitions are wonderful things.  

Just out of curiosity, are you seeing cleistothecia-type things in 
fuzzies not known to make them?
