Type Information: Type: Parmelia moreliense B. de Lesd.

Taxonomic Literature: Taxonomic notes: This species may well be better placed in Rimelia. De Lesdain 1914 Culberson & Culberson 1981.

Biogeography: Neotropical; montane. Continent: Northern America. Checklist records: Mexico and Sonoran Desert.

Ecology: Biotroph; lichenized; corticolous.

Thallus: Foliose, subdivided into main parts, and secondary or without secondary parts, isotomic-dichotomous, continuous throughout, lobed; lobes elongate or linear, horizontal; subconvex; branches applanate (moderately flattened); bifacial; not segmented; separate thallus parts 2-3.5-5-(0) mm wide. Thallus Size and Differentiation: 10-12.5-15 cm in diameter; main branches basally not constricted; apex truncate. Upper Surface: Grey, convex, matt, smooth; not fissurate; not foveate; not convoluted; without patches; epruinose; not pseudocyphellate; not wrinkled; ciliate; cilia slender, marginal; without hairs; not isidate; without isidiomorphs; not papillate, not pustulate; not sorediate; not tuberculate; not lobulate. Lower Surface: Present, black, black in the centre, brown (at tips) along the margin; attached by holdfasts; not cyphellate; not wrinkled, wrinkles central, isolated; rhizinate; rhizines sparse, with a narrow non-rhizinate margin, black, not branched; not tuberculate.

Hydrochasic Thallus Movement: Not performing hygrochasic thallus movement.

Upper Cortex: Double-layered.

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Apothecioid, forming all across the thallus surface, all across the surface, moderately abundant. Margin: Crenulate, epruinose; not sorediate; not isidiate; without pseudocyphellae pseudocyphellae; not ciliate; not hirsute. Disk: Brown.

Asci: Dehiscence lecanoralean.

Ascospores: c. 8 per ascus, ellipsoid, 16-18-20 µm long, 8-9-10 µm wide.

Conidiomata: Present.

Conidia: Filiform; 16-18.5-21 µm long; 1 µm wide.

Secondary Metabolites: Present; only in the upper part of the cortex, throughout the cortex, or throughout the thallus medulla, atranorin, consalazinic acid, gyrophoric acid, norstictic acid, and protolichesterinic acid, metabolite(s) of unresolved identity: absent.

Spot Tests: Cortex: KC + deep yellow; medulla: K + yellow changing to red, C – or + red, KC – or + red, PD + red.
