Chloroidium Nadson

Chloroidium Nadson View in CoL .

All eleven currently accepted Chloroidium species ( Guiry & Guiry 2022) are characterized by an ellipsoidal, ovoid, or spherical cell shape bounded by a relatively thin cell wall that becomes thicker with age, a parietal lobed or lobe-less chloroplast ( Fig. 5 View Figs 1–18 ), and reproduction by unequally sized autospores. Representatives of this genus differ from the other Chlorella View in CoL -like species in the production of ribitol, a metabolite typically produced in response to osmotic stress (Darienko et al. 2010). Chloroidium View in CoL accommodates species, which were previously attributed to the various Chlorella species, including C. saccharophila , C. ellipsoidea , C. angusto-ellipsoidea , and C. viscosum , and later moved to the genus Chloroidium View in CoL based on phylogenetic analyses (Darienko et al. 2010; Darienko et al. 2018). Chloroidium View in CoL is a widely distributed genus that inhabits a variety of environments, including water ( Darienko et al. 2018). Chloroidium ellipsoideum , C. saccharophilum , C. lichinum and C. viscosum were described as lichen symbionts ( Thüs et al. 2011; Vančurová 2012; Darienko et al. 2018).
