Pyrrhospora endaurantia

About

Pyrrhospora endaurantia is a species of lichen in the family Lecanoraceae. Found in Kenya, it was described as a new species in 2021 by the lichenologists Klaus Kalb and André Aptroot. The type was collected on the Roaring Rocks in Tsavo West National Park, at an altitude of about 1,300 m (4,300 ft). Here it was found growing on tree twigs in a savannah. The lichen has a dull, pale grey thallus bordered by a black hypothallus about 0.1 mm wide. The specific epithet endaurantia refers to its orange-red subhymenium and orange hypothecium. The thallus of the lichen turns yellow with the K chemical spot test. Thin-layer chromatography showed the presence of atranorin in the thallus.
