Phaeographis xanthonica is a species of corticolous (bark-dwelling), crustose lichen in the family Graphidaceae. [2] Found in Brazil, it was formally described as a new species in 2009 by Klaus Kalb and M. Matthes-Leicht. The species epithet refers to the presence of the xanthone substance lichexanthone. The type specimen was collected in Itatiaia ( Serra da Mantiqueira, Rio de Janeiro) at an altitude of 1,750 m (5,740 ft). It has also been recorded from Costa Rica. [1]
The thallus of Phaeographis xanthonica is smooth, matt, whitish-grey to whitish-beige, and lacks a prothallus. Its ascomata are lirelline in form, curved with tapered ends, and measure 0.5–4 mm long. The discs are black and bordered by a somewhat thick and split thalline margin. The ascospores have a transverse septum that divides it into four cells; their dimensions fall into the range 11–21 by 5–7 μm. [1]
