Crustose lichens are lichens that form a crust which strongly adheres to the substrate (soil, rock, tree bark, etc.), making separation from the substrate impossible without destruction. The basic structure of crustose lichens consists of a cor ...

Gustav Wilhelm Körber (10 January 1817, Hirschberg – 27 January 1885, Breslau) was a German lichenologist.
He studied natural sciences in Breslau and Berlin, obtaining his PhD in 1839 with the thesis ''De gonidiis lichenum''. After graduati ...

recognized it first as a subgenus of ''Lecidea'', and then a couple of year after as a distinct genus.
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.
Description
''Lecidella'' species have athallus
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 ...
