Diagnostic features.

An orange flattened mass of short oscular tubes, connected at the substratum by a basal tubular network, the erect tubes maybe divided into one or two side tubes. The walls of tubes are thin with spicules are dominated by triactines. Triactines predominantly equiactinal with size 14.93–120.79 (83.54) × 3.39–6.76 (5.48) µm (n = 20). Tetractines are also not rarely found with size 28.04–103.79 (83.77) × 4.98–5.94 (5.48) µm (n = 11).
