SYNOPSIS Telomyxa glugeiformis found in France is structurally identical with the same parasite from Romania. The electron microscope shows that the sporonts in the fat body cells of Ephemera danica develop a double membrane. Electron‐opaque material (which is the polar ring of the future diplospore) is deposited at the opposite poles of the sporont in the space between the 2 membranes. The cell division which follows leads to the formation of 2 sporoblasts and later of 2 spores inside a membrane. The permanent assemblage of 2 spores embedded in electron‐dense material and enveloped by a common membrane is the diplospore, which is thus a special type of pansporoblast. The microsporidan suborder Dicnidea Léger and Hesse, 1922 should therefore be rejected.
