Protococcus

/ˌprəʊtə(ʊ)ˈkɒkəs/

Botany

noun

A genus of the family Ctenocladaceae (formerly Protococcaceae) of unicellular freshwater green algae, chiefly of spherical shape; (also protococcus) an alga of this genus.

Originally applied to Protococcus viridus (also called Pleurococcus viridus), the common green alga which forms patches on tree trunks, walls, etc. The genus has since often been extended to include unicellular algae of many other genera; hence the name is often avoided on account of its perceived ambiguity..

Origin

Mid 19th century; earliest use found in The Penny Cyclopaedia. From scientific Latin Protococcus from ancient Greek πρωτο- + κόκκος grain, seed.
