Description Solitary trochoid to ceratoid, with an epitheca s.l. Calice subcircular and moderately deep. Radial elements are compact, free, straight, slightly curved or even bent septa s. s. Septa show regular variation of their thickness from the center to the periphery. Distal edge poorly ornamented by some regular wide festoons corresponding to the variations in thickness. Lateral faces show the subvertical orientation of these thickest and thinnest bands. Hexameral symmetry not very regular. Bilateral symmetry visible with curvature of septa and eccentricity . Endotheca with tabuloid thick dissepiments. Calicular fossa well marked and eccentric. Wall of unknown nature but peripheric in position (no costae). [details]
Remark Small rows of granules evoked in the fig. 70 of Alloiteau (1957) were not seen and the angle of thick and thin bands with vertical is incredibly exaggerated. [details]
Status Erroneously, Alloiteau (1955) proposed again Plesiophyllum as a new genus for P. harrensis, a coral of Upper Jurassic of Yemen [details]
