Ascophora
Ascophora is an infraorder under order Cheilostomatida of the Bryozoa. They are now considered a synonym of Flustrina. Ascophorans are distinguished from other cheilostomes in having a completely calcified wall covering their frontal surface apart from the orifice, and possessing an ascus (hence the name of the suborder). The ascus is a water-filled sac of frontal membrane opening at or near the orifice. It functions as a hydrostatic system by allowing water into the space below the inflexible frontal wall when the zooid everts its polypide (feeding tentacles) by muscles pulling the frontal membrane inwards (non-ascophorans do not need this structure as their frontal wall is not calcified). The structure of this frontal wall is the basis of distinguishing the four major subdivisions of the Ascophora, each of which is, however, currently under suspicion of being polyphyletic and/or paraphyletic.Gordon, D.P. 2000.

Ascus (bryozoa)
The ascus is a diagnostic morphological feature of the bryozoan suborder Ascophora (hence the name of the suborder). It is a water-filled sac of frontal membrane opening (ascopore) at or near the zooid orifice. It functions as a hydrostatic system by allowing water into the space below the inflexible, calcified frontal wall (covering their whole frontal surface apart from the orifice) when the zooid everts its polypide The polypide in bryozoans encompasses most of the organs and tissues of each individual zooid A zooid or zoöid is a single animal that is part of a colonial animal. This lifestyle has been adopted by animals from separate unrelated taxa. ...

Colonies are often encrusting sheets on shells or rocks. The zooids are characterised by having an operculum that opens in the opposite way to other cheilostome genera; i.e. the hinge is located at the 'top' (towards the growing edge) of the zooid.

Cheilostomatida
Cheilostomatida, also called Cheilostomata, is an order of Bryozoa in the class Gymnolaemata. They are exclusively marine, colonial invertebrate animals. Cheilostome colonies are composed of calcium carbonate and grow on a variety of surfaces, including rocks, shells, seagrass and kelps. The colony shapes range from simple encrusting sheets to erect branching and even unattached forms. As in other bryozoan groups, each colony is composed of a few to thousands of individual polypides. Each individual has a U-shaped gut, and no respiratory, circulatory, or nerve system. Unique among bryozoans, cheilostome polypides are housed in a box-shaped zooids, which do not grow larger once the zooid is mature. The opening through which the polypide protrudes is protected by a calcareous or chitinous lidlike structure, an operculum. Cheilostomes possess avicularia, which have modified the operculum into a range of mandibles (possibly for defense) or hair-like setae (possibly for cleaning). ...

Flustrina
Flustrina is a suborder under the order Cheilostomatida of gymnolaematan Bryozoa (sea mats). The structure of the individual zooids is generally simple, a box-like chamber of calcium carbonate, the polypides reaching out through an uncalcified flexible frontal wall, often surrounded by numerous spines. Like in other gymnolaematans, their lophophore is protruded by muscles that pull on the frontal wall of the zooid. In some treatments, the Flustrina are restricted to the superfamilies Calloporoidea and Flustroidea and ranked as infraorder alongside the Cellulariomorpha which contain the other three superfamilies. What here is considered the Fulstrina is then called the infraorder Neocheilostomina, and in a more radical variant also includes the Ascophora as another infraorder. The obsolete sub-order Anasca previously included the members of this sub-order before being deprecated.

The Adeonidae is a family within the bryozoan order Cheilostomatida. Colonies are often upright bilaminar branches or sheets, perforated by large holes in some species (e.g. ''Adeona cellulosa'').
