Diagnosis
Encrusting to massive growth form. Surface hispid and usually conulose. Choanosomal skeleton basally compressed layer of spongin fibres lying on substrate, with microcionid-like plumose spongin-fibre nodes ascending to surface. Basal fibres cored by pauci- or multispicular plumose tracts of choanosomal styles, with no or few anastomoses. Extra-axial skeleton with few very long thin extra-axial styles, embedded in choanosomal fibre nodes and protruding through surface. Extra-axial spicules also scattered throughout mesohyl. Fibres very heavily echinated by sagittal triacts, tetracts, or forms even further modified, producing almost rigid interlocking secondary skeleton. Ectosomal specialisation absent. Structural megascleres styles or subtylostyles of 2–3 sizes; thinner may have few spines and subtylote swellings on distal and basal ends, respectively; echinating spicules sagittal tetracts or pentactinal megascleres (acanthoplagiotriaenes), less commonly diacts or triacts, with all (s.s.) or at least more than one acanthose ray. Microscleres absent.
