Lichenologist 15: 129 (1983).
Basionym: Parmelia amaniensis J. Steiner & Zahlbr., in Zahlbruckner, Bot. Jahrb. 60: 526 (1926).
Description: Lichen. Thallus foliose, membranaceous to more or less coriaceous, loosely attached, pale grey. Lobes 0.5 - 1.5 cm wide, crenate, ciliate, cilia 3 - 5 - 7 mm long. Upper side emaculate. Medulla white. Under side black, with a narrow brown or rarely white mottled marginal zone, rhizines sparese. Isidia and soredia absent. Apothecia up to 1.7 cm in diameter, submarginal on swollen stipes which become somewhat constricted with age, or marginal and eccentrically situated on semitubular, convoluted lobes, thalline margin normally lobulate-dentate and ciliate, disc imperforate. Spores thickwalled, 25 - 40 / 15 - 18 µm. Pycnoconidia weakly sublageniform, 5 - 8 µm long (Swinscow & Krog 1988: 169).
Photobiont: Probably Trebouxia.
Chemistry:
Ecology: Corticolous. In East Africa in lower montane forest at 800 to 1200 (2000) m altitude, locally common in Tanzania, otherwise rare.
Distribution type: Western and southern Africa. Tanzania, Uganda, Zambia.
Taxonomy: Data lacking.
Note: Parmotrema amaniense may be considered the parent morph of the sorediate Parmotrema subarnoldii (Swinscow & Krog 1988: 169).
