S ummary Electron microscopical examination of cultured Chlorella variegata , a facultatively heterotrophic species of the genus, revealed the presence of electron‐opaque spheres, or pyrenoglobuli, in the pyrenoid. The pyrenoglobuli, observed both in vegetative cells and autospores, are associated with the pyrenoid thylakoids which are single thylakoidal elements penetrating into the homogeneously granular matrix of the pyrenoid. There appear to be more pyrenoglobuli present in the pyrenoids without starch plates.
