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?
1465In cleared and stained root material you have seen structures that appear to be empty sacs in the epidermal cells with ostioles that exit to the soil. Which division are these fungi likely to be from?
1585A 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 2626Toxin 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?
