About Clavulinopsis aurantiocinnabarina (Schwein.) Corner
The fruit bodies of Clavulinopsis aurantiocinnabarina are cylindrical in shape, ranging in color from orange to orange-red. They reach maximum dimensions of 80 mm in length by 6 mm in width, and grow either singly or in small clusters. When examined microscopically, the basidiospores of this species are hyaline and smooth, with a shape ranging from globose to subglobose. Their size measures 5.5 to 7 μm long by 5 to 7 μm wide, and they have a small apiculus. This species was first formally described from collections made in Pennsylvania, United States. Its exact overall distribution remains uncertain, due to historical confusion with similar closely related species, several of which are found in eastern North America. The broader species complex that includes this taxon is widespread across eastern North America. Clavulinopsis aurantiocinnabarina sensu lato has additionally been reported from Central America, the Caribbean, Brazil, China, and Malaysia. This fungus grows singly or in small clusters on the ground, most often in woodland habitats. It is presumed to be a saprotrophic organism.
