with ridge/groove system covered by a thin fused dermal cortex with thick dictyonal strands oriented in all directions; large rough pentactins and occasional subhexactins serve as both dermalia and atrialia. Microscleres are mainly oxyhexasters, oxyhemihexasters, and oxyhexactins, but rare onychohexactins also occur.

Larger inhalant and exhalant canals oriented perpendicular to the outer surfaces are visible through the tissues of both surfaces. The ridge-groove system expected to be present on the basis of spiculation of the specimen, is not visible on either surface. The preserved fragments are white; the texture is stony-hard but the interior is fleshier than that of other dictyonal hexactinellids.
