Polydora

Polydora cornuta, copyright Erica Keppel.


Belongs within: Spionida.

Polydora is a genus of polychaete worms that often burrow into calcareous substrata such as coral reefs or mollusk shells.

Characters (from Williams 2001): Prostomium with anterior incision or rounded; caruncle extending posteriorly, surrouded by cilia of nuchal organ. Segment 1 without notosetae. Segment 5 modified with one type of major spine in single curved row, with or without companion setae; juveniles may possess large, falcate major spines that are replaced by subsequent spines. Posterior notopodial spines present or absent. Bidentate hooded hooks beginning on segments 7–14, main fang at approximately right angle to shaft, wide angle between main fang and apical tooth, with constriction on shaft. Branchiae beginning posterior to segment 5. Pygidium variable: cuff-shaped, cup-shaped with dorsal gap, lobed, scoop-shaped, or with digitiform cirri. Anterior portion of digestive tract lacking gizzardlike structure.

Sarcomeniaceae

Platysiphonia delicata, copyright Tom Schils.


Belongs within: Ceramiales.

The Sarcomeniaceae are a group of red algae intermediate in some respects between the related families Rhodomelaceae and Delesseriaceae: they have pericentral cells in the thallus that are cut off in an alternating sequence as in Rhodomelaceae, but they have tetrasporangia cut off before the cover cells as in Delesseriaceae (Womersley 2003).

Characters (from Womersley 2003): Thallus erect, much branched, branches terete or compressed, usually gelatinous and decaying rapidly. Apical cells prominent, protruding, axial cells with 4 pericentral cells cut off in alternating sequence with the first-formed transverse pericentral cells lying in a linear row. The slightly larger lateral pericentral cells each cut off 2 half-length flanking cells (only associated with reproduction in Malaconema) which produce rows of cells in some genera. Branching endogenous (except for monosiphonous filaments in Dotyella and Sarcotrichia). Trichoblasts absent, but some genera with simple, monosiphonous, rhodoplastic filaments from the pericentral or flanking cells, arising well below the apices, or endogenous from axial cells (in Cottoniella). Reproduction: Gametophytes dioecious. Procarps borne on the adaxial transverse pericentral cells, with a 4-celled carpogonial branch and 2 sterile cells; carposporophytes with a basal fusion cell and much branched gonimoblast with clavate terminal carposporangia, replaced from lower cells; cystocarps external to branches, ovoid to urceolate, pericarp arising post-fertilization, ostiolate, with numerous erect filaments developed from adjacent pericentral cells, each cell cutting off 2–3 outer pericentral cells, corticated or not. Spermatangia borne in sori on the surface of shorter, compressed, lateral blades. Tetrasporangia in stichidia, cut off from lateral pericentral cells, in 2 longitudinal, distichous, rows, in a single layer, with post-sporangial cover cells on both sides.

Belongs within: Rhodomelaceae.

Chondria is a genus of much-branched Rhodomelaceae with distinct pericentral cells throughout the thallus and flat spermatangial plates (Womersley 2003).

Characters (from Womersley 2003): Thallus usually erect, rarely prostrate or free-floating, much branched irregularly radially or unilaterally, rarely subdistichously, with or without one to a few percurrent axes; a few species with tendrils, axillary branches often present; branches terete or compressed, young branches basally constricted. Some species with swollen, bulbous, sterile storage organs. Attachment by discoid holdfasts or haptera from stolons; epilithic or epiphytic. Structure. Apices of branches depressed or rounded, or tapering, with an apical filament usually 10–20 cells long, the subapical cells cutting off 5 pericentral cells in alternating order and branched trichoblasts. Pericentral cells of similar length to axial cells except near apices of tetrasporangial thalli, producing 2–5 series of di- to quadrichotomous branchings, expanding rapidly to form the rounded ends of branches; pericentral cells remaining clear throughout the thallus, cortex of compact, ovoid cells with the epidermal cells ovoid or angular to elongate in surface view. Pericentral and often the inner cortical cells of most species developing wall thickenings of various forms often characteristic of the species. Rhizoids usually formed from pericentral and inner cortical cells, sparse to dense around these cells in larger branches. Secondary cortex absent or present on the lower axes by proliferation of the epidermis. Reproduction: Gametophytes dioecious. Procarps borne on a lower cell of trichoblasts, with the fifth-formed pericentral (supporting) cell bearing a 4-celled carpogonial branch and lateral and basal sterile cell groups; auxiliary cell cut off post-fertilization or in some species the supporting cell acting as auxiliary cell. Carposporophytes with a basal fusion cell and branched gonimoblast with clavate terminal carposporangia, replaced from lower cells. Cystocarps ovoid to slightly urceolate, in some species with a basal spur developed from trichoblast cells above the supporting cell; pericarp ostiolate, with 9–18 erect filaments arising pre-fertilization from adjacent pericentral cells, each cell with 2–3 outer pericentral cells and ecorticate or not. Spermatangial plates flat, discoid or slightly lobed, developed from the whole or a basal branch of a trichoblast, with the primary cells producing a layer of initials each cell of which cuts off 2–4 spermatangia, and with a sterile margin 1–3 cells broad. Tetrasporangia developed in lesser branchlets, cut off singly from near the outer ends of 1–3 radially elongate pericentral cells per axial cell, covered by the outer cortex and epidermal cells.

Bostrychieae

Bostrychia scorpioides, copyright Raquel Sánchez de Pedro.


Belongs within: Rhodomelaceae.

The Bostrychieae is a group of two genera of Rhodomelaceae, distinguished from other members of the family by the absence of trichoblasts, together with distinctive female reproductive features (Womersley 2003).

Characters (from Womersley 2003): Thallus apices dorsiventrally developed, with polysiphonous indeterminate axes bearing polysiphonous and monosiphonous determinate laterals usually at regular intervals; trichoblasts absent; axes attached by clumped rhizoids. Branching mostly exogenous. Polysiphonous branches with 4–9 pericentral cells dividing transversely into 2–5 tiers; ecorticate or corticated. Procarps formed on 2–6 or more successive polysiphonous segments, each segment with 1–4 procarps each with the fertile pericentral (supporting) cell, a lateral sterile group of 2–6 cells and a (3–) 4-celled carpogonial branch; carposporophyte with a branched gonimoblast bearing terminal carposporangia; cystocarps with a post fertilization pericarp of 6–14 longitudinal filaments, each cell cutting off 2 (–3) outer pericentral cells, usually corticated. Spermatangia forming an outer layer on polysiphonous determinate laterals. Tetrasporangial stichidia on determinate laterals, each segment with 4–5 pericentral cells and whorled tetrasporangia, protected by cover cells.

Laurencia

Laurencia obtusa, from here.


Belongs within: Rhodomelaceae.

Laurencia is a diverse genus of erect, often densely branching Rhodomelaceae.

Characters (from Womersley 2003): Thallus erect, moderately to much branched radially or distichously for 2–5 orders, soft to firm, usually drying cartilaginous, branches with truncated apices with a depressed apical pit; holdfast discoid or stoloniferous, epilithic or epiphytic. Structure. Apical depression with a central, short, apical filament bearing well-developed trichoblasts and four pericentral cells per axial cell, axial cells short, these and the pericentral cells soon obscured and not recognisable in sections, cortex extensive with relatively large, ovoid, usually compact, irregular cortical cells and a small-celled epidermis with secondary pit-connections between the cells lengthwise to the branch and usually with corps en cerise; inner cortical cells often producing rhizoids and in some species with lenticular wall thickenings. Lateral branches arising from basal cells of trichoblasts. Cells uni- or multinucleate; rhodoplasts discoid to elongate, often chained in larger inner cells. Gametophytes dioecious. Procarps formed on the fourth pericentral cells on the suprabasal cell of trichoblasts, consisting of a lateral sterile group of 4–6 cells, a four-celled carpogonial branch and a basal sterile group of 2–3 cells. Carposporophytes with a basal fusion cell and branched gonimoblast bearing clavate terminal carposporangia, usually replaced from cells below when lost. Cystocarps usually lateral on branches, usually sessile, basally constricted or broad-based and in some species conical; pericarp arising pre-fertilization, ostiolate, corticated and 3–6 cells thick. Spermatangia borne in lateral whorls on cells of modified trichoblasts in the apical cup-like depressions, each axial cell with four pericentral cells and ultimate spermatangia, the filaments terminated by an enlarged globular cell. Tetrasporangia borne, usually abaxially, on outer ends of laterally elongate pericentral cells or pit-connected to outer cortical cells, usually in "parallel" (down the branch) arrangement, tetrahedrally divided.

Lophothalieae

Micropeuce feredayae, from Phycologia Australica.


Belongs within: Rhodomelaceae.

The Lophothalieae are a Group of Rhodomelaceae characterised by the presence of persistent, rhodoplastic trichoblasts close to axis apices.

Characters (from Womersley 2003): Thallus erect, radially branched, branches clothed with rhodoplastic trichoblasts (usually persistent) developed on successive segments, spirally arranged; pericentral cells 4–7, ecorticate or becoming heavily corticated, in some genera with adventitious monosiphonous filaments from the pericentral or cortical cells. Structure monopodial, with trichoblasts produced close to apices, simple or branched with non-adherent or rarely adherent walls just above the branchings; adventitious filaments simple or branched, arising from pericentral or cortical cells, similar to trichoblasts in dimensions; pericentral cells formed in alternating sequence, undivided or divided in a few species. Gametophytes dioecious. Procarps borne at base of trichoblasts, on the last formed of five pericentral cells, which cuts off a single group or two groups of sterile cells and a four-celled carpogonial branch. Carposporophytes with a basal fusion cell and branched gonimoblast with terminal carposporangia, usually replaced from lower cells. Cystocarps ovoid or urceolate, ostiolate, with cells of the erect filaments producing two outer cells, corticated or not. Spermatangial organs borne as a branch of trichoblasts, axial cells with three pericentral cells producing a layer of initials and outer layer of spermatangia. Tetrasporangia occur in lesser branches bearing trichoblasts or in discrete stichidia borne on the trichoblasts or adventitious filaments, with 4–5 pericentral cells, one, or two opposite ones, becoming fertile; tetrasporangia single, either in a longitudinal line or spirally arranged, or paired and opposite, pairs decussate, with two pre-sporangial and in most genera also one post-sporangial cover cells.
