1962 M. R. Edwards in Abstr. 8th Internat. Congr. Microbiol. 31/1 The ingrowths of the plasmalemma may branch repeatedly and anastomose to give rise to a complicated honeycomb-like organelle. This organelle may be termed a plasmalemmosome in view of its origin from the plasmalemma.
1973 Protoplasma 74 235 The morphology of plasmalemmasomes in the species examined is variable and ranges from vesicles or tubules within the plasmalemma invagination to parallel arrays of membrane lamellae. Plasmalemmasomes thus appear to be primarily excess plasma membrane that has accumulated, perforce, endocellularly.
1984 J. W. Deacon Introd. Mod. Mycol. (ed. 2) ii. 27 The plasma membrane may proliferate in the form of whorls or convolutions, giving rise to structures termed lomasomes or plasmalemmasomes.
