Lecidella
Introduction '''''Lecidella''''' is a genus of crustose lichens in the family Lecanoraceae.
Taxonomy ''Lecidella'' was circumscribed by German lichenologist Gustav Wilhelm Körber in 1855.It was not widely used until more than a century later, when Hannes Hertel 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 a thallus that is crustose, and , meaning that it resembles the genus ''Biatora''–having a proper exciple, which is not coal-black (, but coloured or blackening. It has eight-spored asci of the ''Lecidella'' type. The ascospores are  and hyaline, while the conidia are curved and threadlike.Morphologically similar genera include ''Japewiella'', ''Carbonea'', and ''Tasmidella''.
Species ''Lecidella'' was estimated to contain about 80 species in a popular 2008 text, a number that was used in a (2020) survey of fungal classification. , Species Fungorum (in the Catalogue of Life) accepts 39 species in the genus.
