Genus Entalophoroecia Harmelin, 1974

? Entalophoroecia sp. ( Fig. 40 View FIGURE 40 ; Table 39 View TABLE 39 )

Material examined. VMNH no. 70661, 70662.

Description. Colony encrusting, expanding into elongate lobes from smooth, circular primary disc ( Fig. 40 View FIGURE 40 A). Zooids tubular, transversely wrinkled ( Fig. 40 View FIGURE 40 B, C), with large round pseudopores (10–15 µm diameter, density about 7–9 per 100 µm2) on both proximal adnate region and vertical distal peristomial region ( Fig. 40 View FIGURE 40 F). Peristome tubes variable in length, often broken, rims angular, openings c. 0.6 x 0.9 mm in size ( Fig. 40 View FIGURE 40 E), minute pustules distributed over inner peristomial surface, each c. 5 µm in size.

Remarks. The colonies found in the study were very small, 1–2 mm in size and infertile, suggesting they may be early growth stage of a larger/and or erect species.

Tube length and diameter measurements do not match any Canu & Bassler (1928a) species. The large round pseudopores most closely resemble in size and density ttwo European species, Plagioecia sarniensis and Entalophoroecia deflexa . Plagioeocia sarniensis has an orifice diameter about 0.1–0.15 mm according to Hayward and Ryland (1985b, p. 100) and as illustrated by De Blauwe (2009, p. 121, photo 109). Entalophoroecia deflexa has an orifice diameter of 0.14–0.16 mm (Hayward & Ryland (1985b, p. 113) (see also De Blauwe 2009, photo 118). However, the zooid tubes with their angular ends and the way they are bent unevenly in different directions, rather than being uniformly oriented, are more like the encrusting portions of Entalophoroecia than of Plagioecia .

Distribution. Florida Atlantic coast, Oculina banks.
