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 andL. enteroleucella group.

Description

Lecidella species have a thallus that is crustose, and biatorine, meaning that it resembles the genus Biatora–having a proper exciple, which is not coal-black (carbonised, but coloured or blackening. It has eight-spored asci of the Lecidella type. The ascospores are simple 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. As of November 2024[update], Species Fungorum (in the Catalogue of Life) accepts 40 species in the genus.
