Gelidium micropterum Kützing
Thallus form and type
Flattened thallus tufts Calcareous stones
Lower mid littoral zone and infra littoral fringe
Plants dark red in colour, up to 5 cm tall, growing as tufts or patches, cartilaginous, flattened 0.5 - 2.0 mm broad with blunt apices and sunken growing points; branching bi- or tri-pinnate or irregular sometimes (Figs. a, b); tetrasporangia confined to short swollen fertile tips with rounded ends, scattered all over the surface of the fertile portion; cystocarps swollen, sub-spherical giving fertile tips of the branchlets a blunt appearance.
Gelidium is an important agarophyte in India. The poor biomass and stunted growth make it unattractive.
