Taxonomic remark Originally described as fossil foraminiferan, later interpreted as calcified sheaths of blue-green algae (cyanophytes); Recent examples (from freshwater) apparently referable to Plectonema, see Riding, 1977. From Liu et al, 2015: Bornemann (1886) regarded Girvanella as a cyanobacterium, as did Pollock (1918) who interpreted it as a calcified sheath. Frémy & Dangeard (1935) compared Girvanella with Symploca, and Riding (1977a) compared it with the present-day calcified sheaths of Plectonema (Fig. 3). We therefore tentatively regard Girvanella as calcified sheaths of oscillatoriaceans. [details]
