Fig. 6P.

Material examined.—Hyrnefjellet, sample and one thin section ZPAL Br. 12/H10.

Remarks.—Main branch 0.71 mm wide, secondary branches 0.61 mm wide. Zooecial apertures oval, 0.12–0.13 × 0.15– 0.16 mm. Distance between aperture centers along main branch is 0.37–0.39 mm equaling 12.8–13.5 per 5 mm. Zooecial chamber is elongated parallelogram shaped, no internal septa are observed. Nodes are present along main branch, 0.25–0.26 mm apart. Material and measurements are not sufficient to establish a conclusive specific identification, but the most similar species is Penniretepora disposita ( Trizna, 1939) known from the Sakmarian–Artinskian of Bashkiria, Russia ( Trizna 1939).
