seen?
Forming flat, fan-shaped clusters encrusting hard surfaces. Some resemble
terrestrial bracket fungi or fish scales. They are sometimes seen
on our Southern shores, growing on coral rubble near reefs.
Features: Thin, flat stiff leathery
disks about 2-4cm in diameter, growing in clusters. Only the central
portion is attached to the hard surface, the edges are free. Forming
disks sometimes with a cleft or notch becoming fan-shaped to kidney-shaped.
The edges are paler and may be slightly ruffled. Colours brown or
yellowish-brown often with fine yellow lines radiating from the centre
to the edges. According to Huisman, those growing in deeper may be
entirely upright.
Sometimes confused with Scaly
red seaweed (Peyssonnelia sp.) which are more encrusting
and stiff with a slimy surface.
