Aspicilia intermutans (Nyl.) Arnold - When typically developed easily recognizable by its pale brown areoles with pale marginal zone; however, the pale zone may be wider or narrower, sometimes covering the whole areoles or with branches on the surface. Thus transitions are formed towards A. cupreoglauca and A. cinerea. Major substances: 3 strains: A: norstictic, connorstictic acids (most specimens); B. norstictic, stictic, ?cryptostictic acids; C. none.

Aspicilia substerilis Sipman - (Aspicilia subfarinosa (J. Steiner) Şenkard. & Sipman) This is probably the species reported as A. farinosa from the Aegean. However, it differs from the description in Clauzade & Roux (1985) by the apothecium anatomy, which agrees with A. calcarea. It was reported by myself erroneously as Hymenelia prevostii. Major substances: none.
