Checked: verified by a taxonomic editorDiagnosis Plumularoidea forming colonies with erect cormoids arising either from creeping stolons, or from any strand of a polysiphonic stem formed by stolon-like tubes. Cormoid main axis bears hydrothecae, either simple or bearing hydrocladia in alternate or opposite positions. Cormoid main axis can be accompanied by stolon-like tubes. Hydrocladia either unbranched or branched. Hydrothecae with toothed or untoothed margin. Nematothecae of variable structure, one- or two chambered, movable or immovable, at least three associated with every hydrotheca, one or two inferior and one pair of laterals, nematothecae not fused to the hydrotheca, with the exception of the genus Antennellopsis in which the lateral nematothecae are partly fused to the hydrotheca. Gonophores as fixed sporosacs contained in gonotheca. Gonothecae arising from caulus or hydrocladia, never protected by hydrocladia or modified hydrocladia, not aggregated, usually dimorphic and with at least the female normally bearing nematothecae. [details]
