Diagnosis
Thinly encrusting, massive, digitate, lamellate, flabellate, arborescent or occasionally fistulose growth forms. Ectosomal skeleton composed of monactinal auxiliary spicules in one or two categories forming structures ranging from sparse, mostly membraneous (subgenus Microciona), sparse, paratangential (subgenus Clathria) to a dense erect palisade of brushes on the surface (subgenus Thalysias). Choanosomal skeletal tracts usually enclosed within spongin fibres, sometimes simply with nodal spongin; fibres cored by smooth, basally spined or partially spined principal monactinal megascleres, usually geometrically different from auxiliary megascleres, sometimes secondarily lost and cored by single category of auxiliary subtylostyle (subgenus Dendrocia), or sometimes replaced partially or fully by detritus in fibres (subgenus Wilsonella). Echinating megascleres partially or entirely acanthose, occasionally smooth or vestigial spination, sometimes secondarily lost (subgenera Axosuberites, Isociella). Choanosomal structure ranges from hymedesmioid, leptoclathrid to microcionid plumose (subgenus Microciona), renieroid (subgenus Isociella), plumo-reticulate or reticulate, with (subgenus Axosuberites) or without compressed axis and radial extra-axial regions. Microscleres include palmate isochelae and modified forms, and toxas with smooth or spined points, occasionally absent.
