The species of Anthracoidea on Carex are host-specific smut fungi restricted to sedges belonging to the same or closely related sections. They are characterized by sori that form black, hard bodies around aborted nuts of their hosts. In Carex sect. Hallerianae, only one species, C. halleriana, is known as a host of Anthracoidea. The taxonomic status of this smut fungus was problematic due to a lack of molecular data. It has been reported under different names, mainly as “A. caricis” or “A. irreg
