St. Thomas Mushroom – Ricordea sp. (Atlantic)
Ricordea sp., commonly known as the St. Thomas Mushroom, is a rare and highly sought-after Atlantic mushroom coral prized for its distinct texture, vibrant coloration, and limited availability in the marine aquarium trade. Originating specifically from the Caribbean, these mushrooms are recognized for their thick, bubble-like vesicles covering the oral disc, creating a richly textured appearance that sets them apart from Indo-Pacific mushroom species. Their scarcity, combined with strong visual appeal, makes them a standout piece for collectors and discerning reef keepers.
Unlike more commonly available mushrooms, St. Thomas Mushrooms are infrequently imported and often sold separately due to their limited supply.
