1. Macroconidia are few or absent in many species.2. Macroconidia are able to produce secondary conidia.3. The chlamydospores are round, resting spores, produced on older mycelium or in macroconidia . 4. Blue Fungal spore masses are produced on the roots of the plant where macroconidia are formed. 5. During sporulation, septate hyphae, with macroconidia with tappered tips, and club shaped microconidia are present. 6. The macroconidia are found on dead plant tissue surfaces as well as in groups that look like sporodochia. 7. Macroconidia differ in shape and size between the species, whereas microconidia are rather uniform, oval to globose ( 5x3?m ).8. On the former, growth is slow with and poor sporulation with most strains producing a few abortive macroconidia and sparse microconidia. 9. Macroconidia are one of the overwintering phases of the pathogen and can persist in the soil and plant residue for many years.10. Macroconidia are also hyaline and in spindle-shape ( truncate at the base and narrow down at the basal end ).
