Taxonomic status: This name is currently regarded as a synonym of Phymatolithon.
Comments: In a subsequent general algal treatise, Nardo (1835: 20) reaffirmed his treatment of coralline red algae as plants and provided a classification in which Nullipora was clearly treated as a synonym of Agardhina.
Seven generic names are based on Millepora polymorpha Linnaeus and thus are ultimately typified by the type of Millepora calcarea Pallas. Chronologically these are Apora Gunnerus (1768), Nullipora Lamarck (1801), Agardhina Nardo (1834), Agardhia Meneghini (1838), Juergensia Reichenbach (1841), Phymatolithon Foslie (1898) and Eleutherospora Heydrich (1900). Because Phymatolithon is a conserved name, it automatically takes precedence over the other six names, which must be rejected under ICBN Art. 14.4, irrespective of when they were validly published. Separate entries for each name are provided in AlgaeBase.
An account of the epitype specimen of Millepora calcarea Pallas, the correct name for Millepora polymorpha Linnaeus, is provided by Woelkerling & Irvine (1986, as Phymatolithon calcareum).
Changes in the ICBN necessitated an update (Spencer et al. 2009: 253) to the original typification (Woelkerling & Irvine 1986 58) of Millepora calcarea; the species is now lectotypified by an illustration (Ellis 1755, Tab. 27, Fig. C) cited in the protologue (Pallas 1766: 265) and epitypified by BM 000562555 (Algal Box Collection 1626) housed in the Natural History Museum, London(BM). Further information is provided in the AlgaeBase entry for Phymatolithon.
