You have been provided with a set of plates of fungi isolated from a diseased leaf, one Chytridiomycota, one Zygomycota, one Ascomycota and one Basidiomycota. The signs of infection indicate that the disease has been caused by a member of Ascomycota which does not form a sexual stage easily.

1 2354Toxin X is released only in mature spores of a single fungus and only when both alleles at a single locus are present. The toxin is never observed when the alleles are together in hyphae or modified hyphae. What division is the fungus found in?
