A. delicatula A. papuanorum A. teretiuscula A. uviformis Arctomia is a genus of lichen-forming fungi in the family Arctomiaceae.

[2] The genus was originally circumscribed by Theodor Magnus Fries in 1861.

[3] Molecular phylogenetic evidence revealed inappropriate classifications for two species once placed in this genus, A. insignis (P.M.Jørg.

& Tønsberg) Ertz and A. borbonica Magain & Sérus.

Arctomia fascicularis (L.) Otálora & Wedin (2013) was confirmed to belong to Gabura,[4] a generic placement originally proposed by Per Magnus Jørgensen in 2014.
