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. What features would you look for in your isolates to indicate if the target fungus was present?

2208A sexual spore is formed in a culture from a single isolate. An attachment is found on either side of a sac- like structure, which encloses the spore. Which division does the fungus come from?
1 3439Toxin 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?
