It was first isolated in northern Iran, and is named after its first known host, citrus plants.

L. citricola is phylogenetically related to L. parva, but conidia of the former are longer and wider.

[1] Its conidiomata are stromatic and pycnidial; mycelium is uniloculate, up to 2 millimetres (0.079 in) in diameter, non-papillate and with a central ostiole.

Its paraphyses are hyaline, cylindrical and thin-walled.

Conidia are aseptate, ellipsoid to ovoid and with longitudinal striations.
