Taxonomic remark From Miao et al., 2021: M. carpogenum was originally described from the latest Mesoproterozoic Neryuen Formation, Lakhanda Group in Siberia, and interpreted as intermediate stages of two fusing cells (Hermann, 1979; Hermann in Jankauskas et al., 1989). However, an alternative interpretation of being a large dividing cell at different stages can’t be excluded. It was interpreted as fungal fossils based on morphology (Hermann, 1979), but confirmation of this interpretation would require further evidence, such as molecular signatures indicative of fungal affinity (e.g. Loron et al., 2019a; Bonneville et al., 2020). At present, the biological affinity of M. carpogenum remains uncertain regardless of their varying vesicle outline and large dimension (width 41–146 μm; length 67–240 μm). [details]
