Multilamellar surface layer of the cell wall of Albugo candida and Phycomyces blakesleeanus.

The surface layer of the cell wall of the sporangia of Albugo candida and of the sporangiophores of Phycomyces blakesleeanus was composed of a series of lamellae. The evidence from freeze-fracture, freeze-etch, and single-stage replicas indicated that the lamellae are organized as bilayers, an organization associated with the presence of lipids. The role of these lamellae in dispersibility and resistance is discussed.
