Fig. 6C, D View Fig .
Material.— Three specimens (PAULg. SCH I.4, 8, and 14) from the Middle Devonian ( upper Eifelian –? lower Givetian ) Russ Conglomerate, Schirmeck outcrop, France .
Description.—Cylindrical to scolecoid solitary coral up to 50 mm long and 13–14 mm in diameter, having 28–38 septa of each order. Major septa are short (half as long as the corallite radius) and thick near the wall, thinning towards the axis. Minor septa are either long (3/4 of the major septa in length) or withdrawn. Cardinal major septum as long as the other septa. Small cardinal fossula. Tabularium 9–12 mmwide, free of septa. Dissepimentarium made of an incomplete row of concentric interseptal dissepiments ( Fig. 5D View Fig 2 View Fig ), vertically discontinuous. Dissepiments elongated and vertical. Tabulae irregular, complete or not, concave or convex. External wall thick, festooned.
Remarks.—The combined occurrence of short septa, wide tabularium and scarce dissepiments is unusual but known from North American specimens initially described as Breviphyllum (see Remarks above). The North American Emsian species Breviphyllum lonense ( Stumm, 1937) is larger ( 40 mm in diameter and <40 septa) and displays longer minor septa. Breviphrentis cf. superstes Poty & Denayer in Denayer et al., 2012, with its diameter of 10–17 mm for 25–30 septa of each order is very similar to the present material but differs in having more regular tabulae and minor septa commonly contraclinant.
