Note: Scytonema hofmannii was proposed as a substitute name for S. hoffman-bangii. Both epithets commemorate the Danish botanist, Niels Hofman Bang (for whom the red alga Bangia is also named), so that neither is correctly spelled. When later starting points are abandoned, the correct name for this species becomes Scytonema hofman-bangii. Among numerous taxonomic synonyms cited by Drouet (1973) are eight that are listed separately in this catalogue. (See the appended Reconciliation with Drouetian Classification [p. 79].)
