Lecanora lojkahugoi was formally described as a new species in 2015 by lichenologists Sergey Kondratyuk, Laszlo Lőkös, and Jae-Seoun Hur.

The type specimen was collected from Khaldoj Bay in Cape Bruce near the Slavyanka settlement (Khasansky District, Primorsky Krai); there, the lichen was found growing on siliceous rocks along the sea coast.

Apothecia made by Lecanora lojkahugoi are lecanorine in form, with an apothecial margin extending beyond the rim of the brown disc, and a diameter of up to 0.7 mm.

[1] Shortly after its original description from specimens collected from the type locality in the Russian Far East, Lecanora lojkahugoi was recorded in several locations in South Korea.

Associated lichens in these Korean locales include Pertusaria flavescens, Candelaria concolor, Phaeophyscia orbicularis, Buellia stellulata, Yoshimuria spodoplaca, and Lecanora oreinoides.
