Diagnosis

Digitate, bushy, lobate, lamellate, arborescent, flabellate and vasiform Raspailia; with echinating acanthose rhabdostyles; larger choanosomal styles completely smooth, without any basal rhabd, geometrically different from smaller acanthose echinating spicules; axial skeleton well differentiated from extra-axial skeleton; axial skeleton compressed, composed of reticulate tracts cored by choanosomal styles; extra-axial skeleton plumo-reticulate, with plumose ascending tracts interconnected by transverse tracts both cored by choanosomal styles (forming a reticulation), or reduced to radial tracts of single long extra-axial styles embedded in and perpendicular to axis, protruding through the surface; echinating rhabdostyles more abundant in peripheral skeleton.
