The type specimen was collected in the Littoral de Robin municipality of Trois Rivières, Guadeloupe.

The species had been found decades ago by Father Casimir Le Gallo, who collected many leaf-dwelling lichens that he sent to the National Museum of Natural History, but it was not published and not documented again until its recollection in 2019.

[1] The lichen has a crustose, pale-cream to off-white thallus that is verrucose (covered with tiny warts).

The medulla of Enterographa serusiauxii contains gyrophoric acid, resulting in a positive C+ red chemical spot test.

[1] The lichen is known only from Guadeloupe, where it grows on the living leaves of both Garcinia humilis and Calophyllum calaba near the coast.
