[1] Dirinaria neotropica is characterized by a foliose thallus that is almost crustose, ranging from closely appressed to agglutinated.

Pseudocyphellae are often distinct, marginal, and laminal, usually restricted to the peripheral parts of the lobes, and may sometimes be reticulately confluent.

Secondary metabolites include atranorin in the upper cortex, and divaricatic acid and few terpenes in low concentration in the medulla.

[2] Dirinaria neotropica is found on rocks from sea level to the edges of montane rain forests.

In the Sonoran region, Dirinaria neotropica is known to inhabit various habitats ranging from arid transition areas to oak-conifer forests.
