Phyllopsora amazonica is a species of corticolous (bark-dwelling), crustose lichen in the family Ramalinaceae.

Phyllopsora amazonica was formally described as a new species in 2019 by lichenologists Sonja Kistenich and Einar Timdal.

The type specimen was collected by the authors from the research station of the Estação Científica Ferreira Penna in the Floresta Nacional de Caxiuanã [pt] (Melgaço, Pará), where it was found in a tropical rainforest growing on a tree trunk at a height of 0.7 m (2.3 ft) above the ground.

[2] Phyllopsora halei, found in North America, Africa, and Asia, has a sister taxon phylogenetic relationship with P. amazonica.

[3] They are somewhat similar in appearance, but differ in the prothallus dimensions and colour (in P. halei, it is more prominent, thicker, and reddish brown), the formation of isidia (in P. hali, they sometimes grow directly out of the prothallus), and the overall form of the thallus (P. halei has rosette-like thalli).
