Nomenclature: Current taxonomic status: accepted. Taxonomic rank: species. Currently accepted name Xanthoparmelia segregata Elix & J. Johnst. Xanthoparmelia. Parmeliaceae Zenker (1827); Lecanorineae; Lecanorales.

Type Information: Basionym: Xanthoparmelia segregata Elix & J. Johnst. Type: Xanthoparmelia segregata Elix & J. Johnst.; type specimen label data: J. Johnston 1502; holo: CBG.

Taxonomic Literature: Mycotaxon 33: 360 (1988).

Biogeography: Southern hemispheric. Continent: Australasia. Checklist records: Australia (rare, endemic, in hinterland areas of N.S.W. and Vic.).

Ecology: Lichenized; saxicolous.

Thallus: Foliose (small-foliose, lobate in thallus centre), irregular, lobed; lobes linear (sublinear to subirregular), imbricate (moderately imbricate); separate thallus parts.3-.5-(1) mm wide. Thallus Size and Differentiation: 4-6 cm in diameter. Upper Surface: Lime green (lobe margins black), plane, glossy (shiny) (at lobe apices), smooth; immaculate; isidiate; isidia central, globular or cylindrical (becoming cylindrical or expanding laterally), not ramified or ramified (rarely branched); not sorediate. Lower Surface: Present, brown or pale brown (shiny, darker black-brown at lobe apices); attached by holdfasts (loosely adnate); rhizinate; rhizines sparse, brown (concolorous with lower surface) or pale brown, not branched.

Medulla: White.

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Apothecioid, soon sessile, up to 3 mm in diam.. Margin: Distinct (thalline exciple thick and involute, becoming thinner and crenate); isidiate. Disk: Excavate to plane (becoming +/- flat), pale brown or dark brown.
