Diagnosis
Massive or encrusting growth forms. Surface hispid, with characteristic excavating meandering, sinuous or straight canals and grooves sometimes forming polygonal tuberculate plates. Choanosomal skeleton collagenous, with compressed central portion composed of a confused halichondroid mass of larger choanosomal megascleres ranging from acanthoxeas and oxeas, strongyles or less frequently styles, forming irregular, ascending, multispicular tracts bound together with sparse collagen (spongin fibres present in some species but not all). Subectosomal skeleton composed of ascending tracts of the same spicules running radially or obliquely to the surface, with larger choanosomal megascleres protruding, and frequently cavernous towards the periphery. Ectosomal skeleton without specialised spiculation although smaller (acanth-)oxeas protrude from the subectosomal region, forming a dense ‘peel’ of closely adjacent brushes perpendicular or paratangential. Megascleres consist of two distinct categories of oxeas, strongyles, or more rarely styles, sometimes sinuous and centrally flexed, either entirely smooth or with even spination, the larger choanosomal spicules more variable in their terminations than the smaller ectosomal spicules which are typically oxeas or acanthoxeas. Microscleres raphides in trichodragmata, in one or more categories, the larger usually sinuous or curved.
