Pyrrhospora endaurantia Kalb & Aptroot (2021)

Pyrrhospora endaurantia is a species of lichen in the family Lecanoraceae. Found in Kenya, it was described as a new species in 2021 by lichenologists Klaus Kalb and André Aptroot. The type was collected on the Roaring Rocks in Tsavo West National Park (Central Province), 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 tissue immediately below the subhymenium). The thallus of the lichen turns yellow with the K chemical spot test. Thin-layer chromatography showed the presence of atranorin in the thallus.^[1]
