Clavulina cristata, commonly known as the white coral fungus or the crested coral fungus, is a white- or light-colored edible coral mushroom present in temperate areas of the Americas and Europe. It is the type species of the genus Clavulina.
The commonly used species name cristata was coined in 1790 by Danish mycologist Theodor Holmskjold (as Ramaria cristata). However, Linnaeus described apparently the same fungus as Clavaria coralloides in Species plantarum in 1753. Therefore, according to the International Code of Nomenclature for algae, fungi, and plants, the name Clavulina coralloides should be used in preference to Clavulina cristata, although the latter name is in more common use.
Fruit bodies, which are generally white- to cream-colored, can be up to 8 centimetres (3.1 in) tall, and 2–4 cm (0.8–1.6 in) broad. The coral "arms" are sparingly branched (3–4 times), 2–4 mm wide, smooth, and sometimes wrinkled longitudinally. The tips are cristate, having small pointed projections, and will often darken with age or in dry weather. The fruit bodies have no distinctive odor, and a mild taste.
The fruit bodies may have a darker color either due to natural variation (whereby the appearance of this species may approach and be confused with C. cinerea) or because of infection by a microscopic fungus, Helminthosphaeria clavariarum.
The spores are white, roughly spherical, thick-walled, non-amyloid, smooth, and have dimensions of 7–11 by 6–10 µm.Basidia are club-shaped, 60–80 by 6–8 µm, and 2-spored.Cystidia are absent. Sterigmata, the slender projections of the basidium that bear the spores, may be straight or curved, and up to 7–8 µm long.
