Description:
As emended by Harvey, Broadwater, Woelkerling & P. Mitrovski (2003), the family includes those taxa of Corallinales whose tetrasporangia produce zonately arranged spores and whose tetrasporangia/bisporangia are borne in conceptacles, produce apical plugs, develop beneath multiporate plates, but are not borne individually within calcified sporangial compartments.

Comments:
Gray (1864: 22) originally established the Hapalidiaceae for a single genus, Hapalidium (Kützing 1843: 385), in turn, based on the single species H. roseolum Kützing (1843: 385). Gray's diagnosis ("Frond plain, hyaline, composed of cells"; Gray 1864 was extremely general and made no mention of calcification; with one exception (Gray 1867), the family was not recognized by subsequent authors. Chamberlain (1983: 300) determined that the type of H. roseolum was conspecific with and thus a heterotypic synonym of <i>Melobesia membranacea</i> (Esper) Lamouroux, the type species of Melobesia. Consequently, Hapalidium is a heterotypic synonym of Melobesia. Nevertheless, as noted by Woelkerling (1988: 86) and Harvey <i>et al.</i> (2003: 995), the family name Hapalidiaceae is legitimate and thus available for a family that includes the genus <i>Melobesia</i>. In the context of the present proposal to place all genera of Corallinales (including <i>Melobesia</i>) whose tetrasporangia/bisporangia produce apical plugs and develop beneath multiporate plates in a separate family, the family name Hapalidiaceae becomes the oldest available name.
