Summary
-
1.
The morphology, asexual and sexual reproduction, and zygospore germination of the green flagellate Furcilla stigmatophora is described from naturally occurring and cultured material.
-
2.
Combinations of nine clones were cultured and examined for evidence of mating and zygospore production. There appear to be two mating types.
-
3.
The effects of dry heat and other factors on zygospore germination were tested.
-
4.
Negative phototaxis, positive chemotaxis and positive reaction to higher oxygen concentration were established, while geotaxis was not observed.
-
5.
Growth under various anaerobic and aerobic, light and dark conditions was compared.
-
6.
No evidence of holozoic nutrition was found.
