SUMMARY: The way in which the dolipore apparatus contains hyphal damage, and the process of septal sealing have been studied in using combined light and electron microscopy. The technique used allows the structure of septa in adjacent damaged and undamaged hyphae to be compared. The results show that septal sealing, following damage, is a two stage process. The first is the instantaneous plugging of the pore channel with electron-dense material. The second, beginning several minutes later, involves the detachment of the septal apparatus present in the ruptured compartment and a re-modelling of the septal swelling on the other side of the wall to give a permanent seal. The parenthesomes play no part in the plugging response.
