Found in Dominican amber and described as a new species in 2000, the fossil has been used in subsequent studies of lichen evolution.

The fossil was discovered in Dominican amber and formally described as a new species in 2000 by George Poinar Jr., Eric Peterson, and Jamie Platt.

Because of its resemblance to modern-day members of Parmelia, it has been placed provisionally in that genus, although the authors acknowledge that without sacrificing more of the specimen for analysis, it is impossible to assert this definitively.

[2][3][4] The fossil lichen has a thallus comprising dichotomously branched lobes with a thickness of 30–50 μm.

Algal cells, rounded to somewhat elliptic in shape and measuring 5.8–11.6 μm, are present at the interface between the cortex and the medulla.
