A. Massalski, T. Mrozińska, M. Olech


Lobosphaera reniformis (Wat.) Kom. et Fott (=Chlorella reniformis Wat.) so far known only from Japan, and Papua Island, was for the first time found in Antarctica (King George Island, South Shetland Islands). In laboratory cultures a complete life cycle was obtained, and most of its stages were followed by the electron microscopy. Reproduction is by morphologically different autospores. In some large vegetative cells two Golgi apparatuses lying side by side were observed.
