This species is usually mentioned as A. tongleti Hue, but, to our knowledge, Hue described it in Lecanora and has never transferred it to Acarospora. Olivier (1909) seems to be the first author to have done it. The status of this species requires further studies.

Lit.: Clauzade et al. (1981: 73), Hue (1898), Magnusson (1929: 285-286).
