The cell ultrastructure of the VAM fungus Gigaspora margarita was examined, and its N ‐acetylglucosamine content and distribution were assessed by means of WGA/ovomucoid‐gold labelling. The various ontogenic stages of the fungus were studied with particular reference to cell walls. The results provide new information on chitin incorporation during spore wall development. A decrease of chitin was observed which was correlated to the structural simplification of the fungus wall throughout its life‐cycle. This suggests an involvement of chitin in specific biological functions such as mechanical resistance and plasticity.
