Immersaria Fuliginosa
''Immersaria'' is a genus of lichen-forming fungi in the family Lecideaceae. It has eight species of crustose lichens. Taxonomy The genus was circumscription (taxonomy), circumscribed in 1989 by the lichenologists Gerhard Rambold and M. Pietschmann, with ''Immersaria athroocarpa'' assigned as the type species. The boundaries of ''Immersaria'' were emended in 2022 following the use of molecular phylogenetics to assess the phylogenetic relationships of species in the genus. The study led to the division of ''Immersaria'' into two distinct clades: one comprising species with apothecia and the other containing species with apothecia. As a result, the lecanorine species previously grouped under ''Immersaria'' have now been reclassified into the newly proposed genus ''Lecaimmeria''. Description The genus ''Immersaria'' presents with a crustose lichen, crustose (crust-like) thallus that has shades ranging from yellow-brown, red-brown, orange-brown to simple brown. This crust may occa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...
