AlgaeBase is often a compromise of taxonomic opinions that may or may not reflect your particular conclusions. It is also a work in progress, and is thus incomplete. Please note that AlgaeBase is purely meant as an aid to taxonomic studies and not a definitive source in its own right. You should always check the information included prior to use.

Status: One species of Egregia is currently recognized, despite the wide range of morphological variation recognized on this coast. There is a trend for bumpy (papillate) main axes (rachi) and paddle-shaped (spatulate) lateral blades north of Point Conception, and smooth rachi and narrow (filiform) lateral blades to the south, but this pattern is not constant (see illustrations).

Glossary Synonym: are different scientific names that pertain to the same taxon, for example two names for the same species. One basic principle of zoological nomenclature is that the earliest correctly published and available name (the senior synonym) takes precedence and must be used for the taxon, if no other restrictions interfere.

In addition to the green, green-blue, red, and brown coloration of healthy cyanobacteria, damaged cells may appear turquoise and white as chlorophyll breaks down.
