Are Deuteromycetes Universally Amylolytic?

You are going to have to test an overwhelming number of organisms to prove
any "universal" hypothesis about the Deuteromycetes.
The Deuteromycetes are, basically, "the rest of the fungi" i.e. the
asexual fungi. Their lineages trace to the Basidiomycetes, Ascomycetes,
Zygomycetes, and so forth.
As a group, the Deuteromycetes have no high degree of relationship
phylogenetically, which implies no high degree of relationship
biochemically or physiologically. Within any given "genus" of
Deuteromycetes, there IS, of course, a greater degree of relationship.
I'm not trying to say you are wrong in trying this, but a claim to
anything universal about the Deuteromycetes is a tough nut to crack and
would require a phenomenal amount of testing across all known taxa.
