Ramaria botrytis, commonly known as the clustered coral, the pink-tipped coral mushroom, or the cauliflower coral, is a species of coral fungus in the family Gomphaceae. The type species of the genus Ramaria, R. botrytis was first described scientifically in 1797 by mycologist Christiaan Hendrik Persoon. The robust fruit body can grow up to 15 cm (6 in) in diameter and 20 cm (8 in) tall, and resembles some marine coral. Its dense branches, which originate from a stout, massive base, are swollen at the tips and divided into several small branchlets. The branches are initially whitish but age to buff or tan, with tips that are pink to reddish. The flesh is thick and white. The spores, yellowish in deposit, are ellipsoid, feature longitudinal striations, and measure about 13.8 by 4.7 micrometers. It resembles several species of coral fungi, some of which require microscopy to reliably identify. A widely distributed species, it is found in North America, Australia, North Africa, central and eastern Europe, and Asia. The fungus is mycorrhizal with broadleaf trees, and fruits on the ground in wooded areas. The fruit bodies are edible and young specimens have a mild, fruity taste. Some authors warn of laxative effects in susceptible individuals. The fungus contains several chemical compounds with in vitro biological activity, and fruit bodies have antimicrobial activity against several species and strains of drug-resistant bacteria that cause disease in humans.
