Iyengaria stellata   (Borgesen) Borgesen,  1939 (Algae)
Organism information awaits expert curation
Class: Phaeophyceae

Thallus form and type: Lobed with stellate or antler-like projection

Substratum: intertidal rocks, coralline stones

Occurrence: Lower mid littoral zone and infra littoral fringe, wave exposed rocks

Season: November-april

Abundance: dominant

Plants in very young stages smooth, globular in form, internally solid, composed of a single-layered peripheral or epidermal tissue consisting of consisting of short, closely packed, palisade-like cells with thin walls, possessing numerous chromatophores and covered by a thin cuticle-like layer. Subepidermal tissue composed of small, angular, tangentially flattened cells in the upper one or two layers; large and rather vertically elongated in the lower layers, cell walls slightly thicker, chromatophores few. Lower epidermis composed of bigger cells with more thickened walls, cells forming rhizoids. Surface of the mature thalli forming more or less stellate projections.
Epidermal cells of the projections narrower, sub-epidermal cells vertically elongated possessing a zonate arrangement in a young projection, in older projections the zonate arrangement of the cells of inner layers is lost. Cryptostomata occurring freely on the surface of the thallus.

Plants bearing only plurilocular sporangia, aggregated to form sori, arising from epidermal cells, projecting out, cylindrical in form and mostly uniseriate, sometimes biseriate.
