Sampling date 09/2018. Scale bars indicate 25 µm.

Three images. One synoptical representation of the cell wall and two optical cross-sections showing pyrenoids, storage grains and the cell nucleus.

Note: Cell forms of Xanthidium antilopaeum with a deviating number of spines are known as forma irregularis:
Xanthidium antilopaeum f. irregularis West & G.S.West 1912. Such deviations occurs particularly in X. laeve; Coesel & Meesters (2023*) argue that this do not deserve a separate taxonomic status.
