Lepidocollema

In 2016, the entire family was revised and updated, resulting in the expansion of Lepidocollema to 24 tropical species.

Lepidocollema was originally circumscribed in 1890 by Finnish lichenologist Edvard August Vainio with only the type species, L. carassense.

[1] This lichen is a gelatinous Parmeliella-like species that has a photobiont from the genus Nostoc.

The family Pannariaceae was revised in 2014 with the help of molecular phylogenetics.

[2] Lepidocollema is characterised by the formation of large, flat rosettes on a thick layer of rhizohyphae, the presence of a cellular thalline cortex, apothecia with a thalline margin, asci with a wide apical ring-structure, and thin-walled ascospores.
