    Definitions

From editor or global species database
Comparison Organically united corallites appear to have independently evolved twice, within Merulinidae in Mycedium + Pectinia, and within Lobophylliidae in Echinophyllia + Oxypora (Budd et al., 2012: fig. 2B). Other synapomorphies of the Mycedium + Pectinia clade are polymorphic corallites, extensive coenosteum, unequal costosepta thickness, discontinuous columellae (lamellar linkage), not more than 6 teeth per septum, interarea made up of horizontal bands, and micro-fibrous deposits. Transverse crosses are also lost in this lineage. The clade is highly supported. Mycedium and Pectinia share all morphological traits examined here, as opposed to the paraphyletic Pectinia recovered by molecular data. Physophyllia is also extremely similar on the basis of macromorphology. The lack of distinction between these three genera, and the paraphyly of Pectinia may be grounds for regarding Mycedium as a synonym of Pectinia and/or Physophyllia, but as Mycedium elephantotus remains the only species placed on the morphology tree, no changes are proposed here. Note that quantitative measurements were based on peripheral corallites as structures of the central corallite may be extremely large in comparison. [details]

Diagnosis Colonial, with intracalicular budding only. Corallites polymorphic and organically united; monticules absent. Coenosteum costate, extensive amount (≥ corallite diameter). Calice width medium (4–15 mm), with medium relief (3–6 mm). Costosepta confluent. Septa in 3 cycles (24–36 septa). Free septa present but irregular. Septa spaced < 6 septa per 5 mm. Costosepta unequal in relative thickness. Columellae trabecular and spongy (> 3 threads), < 1/4 of calice width, and discontinuous among adjacent corallites (lamellar linkage). Paliform (uniaxial) lobes weak or moderate. Epitheca absent and endotheca abundant (vesicular). Tooth base at mid-calice circular. Tooth tip at mid-calice irregular; tip orientation perpendicular to septum. Tooth height medium (0.3–0.6 mm) and tooth spacing medium (0.3–1 mm), with no more than 6 teeth per septum. Granules scattered on septal face; irregular in shape. Interarea formed by horizontal bands. Walls formed by dominant paratheca; abortive septa absent. Thickening deposits micro-fibrous. Costa center clusters not distinct; medial lines strong. Septum center clusters not distinct; medial lines strong. Transverse crosses absent. Columella centers clustered. [details]

Remark This genus has commonly been regarded to be similar to Echinophyllia (Lobophylliidae), because of its laminar growth form (Vaughan and Wells, 1943: 198; Wells, 1956: F419; Veron and Pichon, 1980: 319; Veron, 1986: 382; Veron, 2000, vol. 2: 342). The lack of distinct corallite walls, or corallites being 'organically united' (Vaughan and Wells, 1943: 196), is a distinguishing feature of Pectiniidae, the family in which Mycedium and Echinophyllia were placed prior to revision by Budd et al. (2012). It is now clear based on molecular phylogenetics that this genus is closest to and also nested within Pectinia de Blainville, 1825: 201 (Fukami et al., 2008; Huang et al., 2011, 2014; Huang, 2012; Arrigoni et al., 2012). [details]

Status Mycedium was originally described by Oken (1815). According to ICZN Opinion 417 (September 1956), the names originally proposed by Oken (1815) are rejected. Therefore authorship is assigned to the second person who used the name. The holotype of Madrepora elephantotus Pallas, 1766, p. 290, is lost (Chevalier, 1975, p. 338). [details]
