Taxonomic remark From Strother & Wellman, 2015: Zhang (1982) erected the taxon Torridoniphycus lepidus for what he considered to be a cyanobacterium (blue-green alga) with a complex life cycle, from microfossils extracted from shales of the Aultbea Fm (Torridon Group). He documented the presence of smaller cells, some of which were referred to as spores, down to about 10 μm in diameter, but the bulk of specimens attributed to the genus, including the holotype, were significantly larger and more complex. Given the size range, complexity and morphological variety of the specimens attributed to Torridoniphycus, these would probably be interpreted to be of a eukaryotic nature today (Strother et al. 2011).
