What Divers Should Know About White Coral

While the name "white coral" might suggest a creature of our vibrant reefs, the species described here, Clavulina cristata—also known as the wrinkled coral fungus or white coral fungus—is actually a fascinating organism of terrestrial environments. As an expert marine biologist and dive guide, my focus is typically on the wonders beneath the waves, but it's important to clarify that this particular "coral" is a mushroom. It thrives in temperate forests across the Americas and Europe, growing on the ground or occasionally on rotten wood, far from any dive site.

These distinctive fruiting bodies, which can reach up to 8 centimeters in height and 4 centimeters in breadth, are generally white to cream-colored. Their sparingly branched "arms," typically 2–4 millimeters wide, often feature small pointed projections at their tips, resembling miniature white branches. While visually striking on the forest floor, its habitat confirms it's not something we would encounter during a dive.
