Nitophyllum

Nitophyllum punctatum, copyright Bernard Picton.

Belongs within: Delesseriaceae.

Nitophyllum is a genus of delesseriaceous red algae with a membranous thallus lacking a midrib (Womersley 2003).

Characters (from Womersley 2003): Thallus foliose to deeply dissected, membranous, without midrib or veins, monostromatic above, becoming tri- or polystromatic below; holdfast discoid or fibrous. Growth apical when very young, otherwise marginal and intercalary. Cells equivalent when polystromatic. Cells multinucleate. Gametophytes dioecious. Procarps scattered, formed usually in opposite pairs, primary cell cutting off a cover cell and a supporting cell bearing a single, 1-celled, lateral sterile group and a 4-celled carpogonial branch. Carposporophyte with a small basal fusion cell and much branched gonimoblast bearing terminal (often sequential) clavate carposporangia, occasionally in chains. Cystocarps hemispherical, ostiolate; pericarp 3–4 cells thick. Spermatangial sori scattered, with primary cells bearing layer of cortical cells which cut off elongate spermatangia. Tetrasporangial sori scattered, with cortical filaments and tetrasporangia cut off from primary cells or inner cortical cells and covered by outer cortex.
