Type Information: Basionym: Parmelia mougeotina Nyl. Type: Parmelia mougeotina Nyl.; type specimen label data: C. Knight; holo: H-NYL 34661.

Taxonomic Literature: New Zealand J. Bot. 18: 538 (1981).

Biogeography: Southern hemispheric. Continent: Australasia. Checklist records: Australia (common and widespread throughout Australia (W.A., S.A., Qld, N.S.W., A.C.T., Vic. and Tas.)) and New Zealand.

Ecology: Lichenized; saxicolous; growing under conditions which are moist (in areas of moderate to higher rainfall).

Thallus: Foliose (foliose to subcrustose, +/- rosette forming), isotomic-dichotomous (dichotomously branched), lobed; lobes elongate or linear (sublinear); concave (slightly concave) or plane; separate thallus parts.5-1-(1.5) mm wide. Thallus Size and Differentiation: 3-5-(8) cm in diameter. Upper Surface: Lime green (pale yellow-green, darkening to yellow-brown or black in thallus centre), matt or glossy (shiny) (shiny at lobe apices); fissurate (cracked near thallus centre becoming crustose-areolate); fissures not particularly oriented oriented; not convoluted; isidiate (sparse, fragile to robust, slender (0.04-0.08 mm wide) and small (01.-0.2 mm high)); isidia central or peripheral, globular (subglobose and inflated) or cylindrical, not ramified, darkened at the tip (isidia apices brown, syncorticate); not sorediate. Lower Surface: Present, black (wholly black or partly black-brown, shiny, smooth); attached by holdfasts (very tightly adnate); rhizinate; rhizines sparse, black, not branched.

Medulla: White.

Reproduction Strategy: With sexual (and possible asexual) stages (but rare). Ascocarps: Soon sessile, up to 1 mm in diam.. Margin: Smooth, distinct or indistinct (prominent, entire); not isidiate. Disk: Excavate to plane, dark brown.

Ascospores: 7-9 µm long, 5-6.5 µm wide.

Conidiomata: Present (but very rare).

Conidia: Bifusiform; 7-9 µm long; 1 µm wide.

Secondary Metabolites: Present; constictic acid, norstictic acid, stictic acid (other secondary metabolites: cryptostictic acid (trace) and +/- menegazziaic acid (trace)), and usnic acid, metabolite(s) of unresolved identity: absent or present.

Spot Tests: Cortex: KC – medulla: K + yellow, C –, KC –, PD + orange.

UV-Fluorescence: Upper thallus surface – (negative).
