A phylogenetic analysis of the genus using 11 species (mostly from China) found that ''Lecidella'' species fall into three major clades, which were proposed as three informal groups: ''Lecidella stigmatea'' group, ''L. elaeochroma'' group and'' L. enteroleucella'' group.

Thallus (plural: thalli), from Latinized Greek (), meaning "a green shoot" or " twig", is the vegetative tissue of some organisms in diverse groups such as algae, fungi, some liverworts, lichens, and the Myxogastria. Many of these organisms ...
