Parmotrema abessinicum is a species of corticolous lichen in the family Parmeliaceae. It has been recorded from Africa, Asia, and Oceania.

Taxonomy[]

The lichen was first described scientifically in 1887 by German lichenologist August von Krempelhuber as a species of Parmelia.[2] Mason Hale transferred it to the genus Parmotrema in 1974.[3] The specific epithet abessinica is derived from the Latin abessinicus (meaning "from or belonging to Ethiopia")[1] and refers to the location of its holotype collection. It has also been recorded from Madagascar,[4] Rwanda,[5] India,[6] Sri Lanka,[7] and Fiji.[8]

Description[]

The thallus is loosely attached to its substratum, and measures 5–7 cm (2.0–2.8 in) across. Its lobes are thick, with a scalloped (crenate) margin, and typically measure 5–10 mm wide. The margins have simple, unbranched cilia up to 3 mm long.[9] Distinguishing morphological characteristics of Parmotrema abessinicum include its ciliate lobe margins, perforate apothecia, and simple rhizines in the thallus centre. It contains the secondary compounds atranorin, , and .[8] The ascospores of this species are simple and colourless, measuring 15–25 by 8–13 μm.[9]
