Fellhanera robusta is a species of crustose lichen in the family Pilocarpaceae.

Found in Australia, it was described as a new species in 2017 by lichenologists John Elix and Patrick McCarthy.

[1] The thick, whitish lichen thallus of Fellhanera robusta forms irregularly shaped discs measuring up to 5 cm (2 in) in diameter.

The authors describe it as "variously verrucose, bullate or contorted" and "irregularly cerebriform"; its specific epithet alludes to its unusual form.

[1] A lookalike species, Fellhanera incolorata, grows on mangrove bark in southern New South Wales.
