Diagnosis
Cylindrical, arborescent or encrusting and massive growth forms. Surface not prominently hispid but evenly conulose. Axial and extra-axial skeletons well differentiated. Choanosomal skeleton markedly axially compressed, with a dense reticulate core occupying a large proportion of branch diameter composed of short, stout oxeas, anisoxeas or occasionally styles. Echinating megascleres absent. Extra-axial skeleton plumose, with uni- or paucispicular tracts radiating towards surface, cored by long, thick subectosomal styles or anisoxeas. Ectosomal skeleton with a special category of styles (sinuous and apically pronged in the type species), forming erect bouquets or paratangential brushes around extra-axial spicules, and also scattered within the mesohyl. Structural megascleres short oxeas and long styles, some with strongylote or oxeote modifications, and ectosomal styles. Microscleres raphides occurring singly or in bundles (trichodragmata).
