Loekoesia is a genus of lichen-forming fungi in the family Teloschistaceae.[1] It contains three species of saxicolous (rock-dwelling), crustose lichens. Collectively, the genus occurs in South Korea, Mauritius, and the United States. The genus is distinguished by its grey, crust-like thallus, which can be either whole or divided into patch-like segments. Loekoesia lichens have bright white, rounded soralia, which produce bluish to whitish powdery propagules (soredia) and are arranged in irregular groups on the thallus.
Loekoesia was circumscribed as a new genus in 2015 by the lichenologists Sergey Kondratyuk, Soon-Ok Oh, and Jae-Seoun Hur. The type species, Loekoesia austrocoreana, was shown with molecular phylogenetics to form a clade with Jasonhuria, another genus in the subfamily Caloplacoideae that was also circumscribed in the same publication. It was initially the sole species in the then monotypic genus,[2] but two additional species were transferred from other genera (Caloplaca and Lecanora) in 2020.[3][4] The genus name honours the Hungarian lichenologist László Sándor Lőkös for his contributions to the body of knowledge about lichens in North and South Korea.[2]
