PARAMURAL BODIES OF ALBUGO-CANDIDA

The paramural bodies of A. candida were formed solely by elaboration of the plasmalemma. Two major forms were recognized: one consisting of plasmalemmal invaginations projecting into the cytoplasm; the other appearing like a pocket containing a number of vesicles and tubules. It is suggested that the first is the basic form of paramural body. In sporangia the paramural bodies break away from the plasmalemma and undergo autodigestion while in vegetative hyphae their tubules and lamellae break up into vesicles that are finally sequestered into the wall.
