Abstract

Micarea argopsinosa sp. nov. (lichenized Ascomycota, Pilocarpaceae) is described from sheltered granite below the summit of Mt Ginini in the Australian Capital Territory. It has a thin, diffuse, greyish green thallus containing only argopsin, solitary or clustered, jet-black, convex apothecia with a K– and C– hymenium and a hyaline hypothecium, comparatively small 3-septate ascospores, and narrowly oblong to filiform, straight, curved or arcuate macroconidia with (1–)3-septa. A key is provided to distinguish the new species from broadly similar taxa known from Australia and elsewhere.
