Overview
Rhodactis is a corallimorph mushroom; specimens with inflated bubble-like vesicles are called 'bounce' and are highly prized. It prefers low-to-moderate light and gentle flow, shrinking under intense light or flow. Hardy and reproducing by division, it needs a stable environment to maintain color and vesicles. It settles well when placed in a rock depression as a single disc.
