Saccharomycomorpha is a genus of non-flagellated protists with a rare yeast-like appearance, containing the single species Saccharomycomorpha psychra. It is the only genus of the family Saccharomycomorphidae (=Clade T), within the cercozoan order Glissomonadida.

Morphology and behavior

Saccharomycomorpha psychra is a unicellular protist composed of round unflagellated cells, which is a unique morphological characteristic among Glissomonadida. It is able to withstand temperatures of 4 °C and its optimal growth is mainly 20 °C, making it a psychrophilic organism.

Ecology

The species was isolated from lichen and moss found in both the Arctic (Svalbard) and maritime Antarctica (King George Island), respectively. These areas have a flora mainly consisting of lichens and mosses. Although glissomonads are mainly bacterivorous, Saccharomycomorpha is perhaps an osmotrophic or parasitic species, since it is able to grow in a culture medium without the presence of bacteria.
