Lepidocollema is a genus of lichens in the family Pannariaceae. It was created in 1890 to contain a single Brazilian species that has not been collected since. In 2016, the entire family was revised and updated, resulting in the expansion of Lepidocollema to 24 tropical species.
Taxonomay[]
Lepidocollema was originally circumscribed in 1890 by Finnish lichenologist Edvard August Vainio with only the type species, .[1] This lichen is a gelatinous Parmeliella-like species that has a photobiont from the genus Nostoc. It has only been collected once from Brazil. The family Pannariaceae was revised in 2014 with the help of molecular phylogenetics.[2] As a result, the genus was accepted and 23 tropical species were transferred into it, mostly from the genus Parmeliella. Phylogenetically, Lepidocollema is sister to Physma.[2]
Description[]
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. Other than the type species, the thallus is in all Lepidocollema species.[2] This refers to a tissue arrangement whereby the mycobiont (hyphae) and photobionts (algal cells) are arranged in distinct layers.
