Summary

  1. 1.

    The structure and plugging of septa of several Neurospora crassa strains were studied.

  2. 2.

    Septa were occluded by an electron dense plug. Woronin bodies were never observed.

  3. 3.

    Nearly all the septa found within the peripheral 0.5 to 1.0 mm of colonies of spco 12 were plugged but plugged septa were never observed in cot 3 and only rarely in spco 4, even 11 mm from the colony's circumference.

  4. 4.

    Lines of vesicles were observed in the cytoplasm and traversing the septal pores of spco 1 hyphae. The mean diameter of these vesicles and the vesicles found at the hyphal tip were identical.
