This species is unique due to its distinct features such as a crumpled, blue-grey to brown thallus (the main body of the lichen) and the production of structures called goniocysts at its margins.

[2] The type specimen was collected by the authors from the Forêt de Bébour [fr] in Réunion, at an altitude of 1,850 m (6,070 ft).

[1] Gabura borbonica is recognised by its foliose (leaf-like) thallus, which is typically crumpled and varies in colour from blue-grey to brown.

[1] Gabura borbonica has been found in various sites across Réunion Island, including in highly disturbed secondary thickets with Eucalyptus plantations.

It has been observed growing on trunks of Eucalyptus and Acacia heterophylla trees, as well as on the main stems of Erica thickets.
