Phyllopsora concinna is a species of corticolous (bark-dwelling), squamulose (scaley) lichen in the family Ramalinaceae.

[2] Found in Central and South America, it was formally described as a new species in 2019 by lichenologists Sonja Kistenich and Einar Timdal.

Ascospores are simple (i.e., lacking septa) with a narrow ellipsoid to fusiform shape, and dimensions of 12.5–16·0 by 3.5–4.0 μm.

The latter compound distinguishes it chemically from the morphologically similar species Phyllopsora cinchonarum, which instead contains lobaric acid.

The botanical name concinna (from the Latin concinnus, meaning "pretty" or "pleasing"), refers to its "beautiful" appearance.
