DESCRIPTION

Branched colony with 4-6 rows of short tubular autozooecia opening on the one side, 0.66-0.75 mm wide. Autozooecia elongated oval to slightly rectangular in deep tangential section having well developed vestibule. Autozooecial apertures oval to lens-shaped, spaced 5 at distance of 2 mm. Thin ridges between apertures separating drop-shaped areas around apertures. Small pit-like heterozooecium (leptozooecium) positioned at distal part of such an area, triangular to rounded in cross section, 0.06- 0.075 mm in diameter. Single small acanthostyle in the wall between the heterozooecium and the adjacent aperture; rare smaller styles irregularly spaced between apertures. Inner granular skeleton hyaline, well developed; outer lamellar skeleton relatively thick.
