Clavulinopsis aurantiocinnabarina is a clavarioid fungus in the family Clavariaceae. It has been given the English names of orange spindle coral[1] or orange worm coral.[2] It forms cylindrical, orange fruit bodies that grow on the ground in woodland litter. It was originally described from the United States and is part of a species complex as yet unresolved.[3]
The fruit body of Clavulinopsis aurantiocinnabarina is cylindrical, orange to orange-red, up to 80 x 6 mm, growing singly or in small clusters. Microscopically, the basidiospores are hyaline, smooth, globose to subglobose, 5.5 to 7 by 5 to 7 μm, with a small apiculus.[5]
Similar species
Clavulinopsis fusiformis is similarly shaped, but fruit bodies are yellow rather than orange and typically appear in dense, fasciculate (closely bunched) clusters. Clavulinopsis laeticolor is also yellow and can be distinguished by its ellipsoid spores. Clavulinopsis sulcata is closely related, but was originally described from Asia and has orange-pink fruit bodies.
Distribution and habitat
The species was initially described from Pennsylvania, but its distribution is uncertain because of confusion with similar, closely related species several of which occur in eastern North America.[3] The species complex is widespread within this area and C. aurantiocinnabarinasensu lato has also been reported from Central America and the Caribbean,[6] Brazil,[7] China,[8] and Malaysia.[9]
The species occurs singly or in small clusters on the ground and is presumed to be saprotrophic. It typically grows in woodland.
