Pyxine philippina

Pyxine philippina is a species of foliose lichen in the family Caliciaceae. It was first discovered in the Philippines, growing on tree bark in the mountainous regions of Luzon. The lichen forms a thin to moderately thick, leaf-like body with a whitish upper surface and blackish underside, anchored by short root-like structures called rhizines. Since its original description, it has been widely documented across Asia, including in Bhutan, India, Japan, Nepal, and Thailand.
