Mississippian ; Ireland . DIAGNOSIS. — Acanthocladiid forming delicate irregularly branching colonies; branches divide, or develop as lateral branches; branches straight or gently flexulous and taper distally, with four to seven rows of autozooecia on main and lateral branches; reverse surface longitudinally striated with microstylets; autozooecial bases pentagonal to hexagonal (diamond-shaped) (modified after Wyse Jackson, 1988 , p. 198, Wyse Jackson, 1996 , p. 140). OCCURRENCE. — Two definite species are known: Baculopora megastoma ( M’Coy, 1844 ) from the Mississippian of Ireland, Germany , Russia , and B. redondensis n. sp. from the Mississippian of France (present paper). Baculopora sp. was mentioned from the Mississippian of Mongolia ( Morozova et al. 2003: 131 ). COMPARISON Baculopora Wyse Jackson, 1988 resembles Ichthyorachis M’Coy, 1844 in possessing four to six rows of autozooecia on branches, but lacks regularly offset or opposite secondary lateral branches. R EMARKS The species Pseudohornera ossipovae Schulga-Nesterenko, 1955 from the upper Visean (Mississippian) of Russia coincides in its morphology and dimensions with Baculopora megastoma ( M’Coy, 1844 ) . Therefore, Pseudohornera ossipovae is synonymised with the latter species.
