[TLC: norstictic acid, galbinic acid, salazinic acid, atranorin.] Thallus corticolous, loosely attached, pale green-grey. Lobes up to 06 cm broad, deeply divided, laciniae 1*2-1 '5 mm broad, sublinear, dichotomously branched, ciliate, cilia 1-2 mm long. Upper side faintly to distinctly maculate, often cracked. Medulla white. Underside black in the centre, with a white or mottled marginal zone mainly restricted to the laciniae, rhizines short, sparse, in the centre of the thallus. Soralia labriform at the tips of the laciniae, soredia farinose. Apothecia and pycnidia not seen. TLC: norstictic acid, galbinic acid, salazinic acid, ± fatty acid (trace), atranorin. The narrow laciniae and labriform soralia distinguish P. parahypotropa from all other Amphygmnia species in our area. In East Africa P. parahypotropa is restricted to the coast of the Indian Ocean, where it has been collected on twigs in mangroves and on the trunk of a Cocos at 300 m altitude. It has been reported from similar habitats in Australia by Stevens & Rogers (1979). East African records Kenya.
