Lecanactis proximans is a species of terricolous (ground-dwelling) crustose lichen in the family Roccellaceae.

[2] Lecidea proximans is a crustose lichen that grows on soil and is strongly attached to its substrate.

Despite recent surveys in similar habitats in the Eastern Hills of Bogotá, the species has not been found again since its original collection by Alejandro Lindig.

The main threats to Lecidea proximans are habitat alteration, deforestation, and expansion of agricultural, industrial, and urban areas.

[3] The species is known only from a single record in the montane humid forests of the Cerros Orientales [es] (Eastern Hills) in Bogotá, Colombia, at an elevation of 2,700 metres above sea level.
