Type Information: Basionym: Parmelia substrigosa Hale. Type: Parmelia conspersa var. strigosa Müll. Arg.; type specimen label data: Falck 12; holo: G.

Biogeography: Southern hemispheric. Continent: Australasia. Checklist records: Australia (very common and variable, found in tableland and mountain areas of southern and eastern Australia (W.A., S.A., Qld, N.S.W., A.C.T., Vic. and Tas.); also on both islands of New Zealand (in particular Canterbury, Otago)) and New Zealand.

Ecology: Lichenized; terricolous or saxicolous (grows on rock and spreads from rock onto soil).
