Species Profile

Solitaria is a fungal genus in the family Teloschistaceae. It contains a single species, the corticolous (bark-dwelling), crustose lichen Solitaria chrysophthalma.

Solitaria chrysophthalma faces severe population declines due to extensive habitat destruction from deforestation and agricultural expansion across its limited range. The species' specialized habitat requirements and small, fragmented populations make it extremely vulnerable to environmental changes and human disturbance.
