Summary

Carpospores ofG. clavatum have been studied under the light and electron microscopes. They are wedge-shaped cells of 80–100 μm at their longest diameters. The nucleus is an uncondensed structure provided with a regular outline and a large nucleolus. The plastids constitute heterogeneous populations of organelles differing in size and shape as well as in number and arrangement of the thylakoids. Multiplicating plastids are also present. The mitochondria are small but have well developed cristae. The Golgi apparatus consists of very numerous active dictyosomes. Starch is the main storage substance but some large lipid bodies are also present. Labyrinthine polysaccharide aggregations are present in the carposporial cytoplasm. Multilayered bodies constitute a “sui generis” very conspicuous cell component.
