Type Information: Basionym: Parmelia praegnans Elix & P. M. Armstr. Type: Parmelia praegnans Elix & P. M. Armstr.; type specimen label data: R. B. Filson 1562a & S. Filson; holo: MEL.

Biogeography: Southern hemispheric. Continent: Australasia. Checklist records: Australia (relatively common, endemic, in inland areas of Australia (W.A., N.T., S.A. and Qld)).

Thallus Size and Differentiation: 2-4 cm in diameter. Upper Surface: Lemon (citrine), matt; fissurate (older lobes cracked, becoming areolate); fissures not particularly oriented oriented; immaculate; isidiate (numerous, isidia apices epicorticate, becoming inflated and erumpent but not sorediose); isidia globular or cylindrical (becoming subcylindrical), ramified; not sorediate.
