Chrysococcus diaphanus is a loricate chrysophyte alga in the genus Chrysococcus, family Chromulinaceae. The epithet diaphanus (Greek/Latin: transparent or see-through) describes the delicate, translucent quality of the lorica that encloses the cell body. This silica-reinforced or organic covering is a diagnostic feature of the genus, encasing the photosynthetic protoplast while allowing the flagellum to project through an apical aperture. C. diaphanus is found in freshwater and brackish environments, with records from Scandinavian and northern European lakes and ponds. Chrysophytes of the loricate type are common in oligotrophic and subarctic freshwaters, where they form a regular component of the flagellated phytoplankton and nanoplankton communities. The genus Chrysococcus includes species that range from purely phototrophic to fully heterotrophic, with many displaying intermediate mixotrophic strategies depending on light availability and prey abundance. Loricated chrysophytes are also valuable in paleolimnology because the siliceous cysts and scales they produce are preserved in lake sediments for millennia, recording past environmental conditions. The species has not been formally assessed for conservation status and is listed as Not Evaluated by the IUCN.

Chrysococcus granulatus is a unicellular freshwater chrysophyte microalga in the genus Chrysococcus, class Chrysophyceae. The species epithet granulatus — granular or granulated — describes a textured surface on the lorica of this species, a feature visible under electron microscopy that contrasts with the smooth surfaces of some congeners. In the genus Chrysococcus, the lorica is a secreted outer covering enclosing the cell, and its surface texture, shape, and any projections or pores form the primary morphological characters distinguishing species from one another. C. granulatus has been documented from Norwegian and Swedish freshwater bodies, consistent with the strong Scandinavian research tradition in chrysophyte taxonomy. Scandinavian oligotrophic and mesotrophic lakes are important reservoirs of chrysophyte diversity, harboring numerous species of Chrysococcus, Chromulina, Ochromonas, and related genera. Records from Brazil and Denmark extend the known distribution of C. granulatus, suggesting cosmopolitan or at least widespread dispersal capability through passive transport mechanisms such as wind, waterfowl, and hydrological connectivity. The species is a golden-brown phytoplankton organism with chlorophylls a and c and fucoxanthin carotenoids, enabling photosynthesis in the limnetic zone. Like other Chrysococcus species, C. granulatus may supplement photosynthesis with phagotrophic uptake of bacteria. It has not been assessed under IUCN criteria and carries a conservation status of Not Evaluated. The species contributes to understanding freshwater chrysophyte taxonomy and biodiversity in Scandinavian aquatic ecosystems.
