Taxonomy Detail

Order Nemastomatales

Nemastomatales Kylin, 1925: 39.

Type of name: Nemastoma

Source: Huisman, J.M. (2018). Algae of Australia. Marine benthic algae of north-western Australia. 2. Red algae. pp. [i]-xii, 1-672, 189 figs. Canberra & Melbourne: ABRS & CSIRO Publishing.

Original publication: Kylin, H. (1925). The marine red algae in the vicinity of of the Biological Station at Friday Harbor, Wash. Lunds Universitets Årsskrift, Ny Följd, Andra Afdelningen 21(9): 1-87, 47 figs.

Structure multiaxial; medulla and cortex filamentous, with or without vesicular cells. Spermatangia terminal on surface cells in diffuse patches or sori. Carpogonial branches 3 (–5)-celled, issuing branched connecting filaments either directly or from one or both halves of the divided zygote. Connecting filaments growing to auxiliary cells or first fusing with nutritive auxiliary cells borne distally on supporting cells, then progressing to auxiliary cells. Auxiliary cells intercalary in cortical branches distant from carpogonial branches; connecting filaments diploidising auxiliary cells via a lateral fusion, either terminating or progressing to additional auxiliary cells. Gonimoblasts arising laterally or outwardly either from the auxiliary cell or from the connecting filament adjacent to the fusion. Carposporophytes mostly outwardly directed and consisting of 1–3 gonimolobes of synchronously maturing carposporangia. Cystocarps compact, ostiolate or not. Tetrasporophytes crustose or of acrochaetioid filaments, with zonate tetrasporangia. Life history triphasic, with heteromorphic gametophyte and tetrasporophyte.
