Abstract
The sequence of sporogenesis using light, transmission, and scanning electron microscopes is reported for nine genera of the Musci: Weissia controversa, Acaulon muticum var. rufescens, Astomum muhlenbergianum, Bruchia drummondii, Clasmatodon parvulus, Ditrichum pallidum, Leucodon julaceus, Physcomitrium pyriforme, and Funaria hygrometrica. Dense amoeboid sporocytes were observed surrounded by gray matrix-like material. In time sporocytes enlarge, become more vacuolated and less dense. During this phase of development the archesporial septa gradually disappear. The events of meiosis are documented multi-vesiculated bodies, vesicles, mitcochondria and lipid bodies are shown indicating the planes of division during cytokinesis of the sporocyte. Plastid development is followed from its occurrence in the young developing sporocyte to the mature spore.
