Cryptoschizotrema Cryptotrema
''Cryptoschizotrema'' is a genus of lichen-forming fungi in the family Graphidaceae. It has two species. The genus was circumscribed in 2019 by lichenologists André Aptroot, Robert Lücking, and Marcela Cáceres. The genus name alludes to the similarity in anatomy with '' Schizotrema'' species. This resemblance is due to the partially , concentrically layered, and fissured , which gives the impression that the ''Schizotrema''-like excipulum is concealed beneath a protective layer. The type species was originally described by William Nylander in 1867, as a species of ''Thelotrema''. Description The ascomata of ''Cryptoschizotrema'' lichens are immersed- and rounded, with the concealed beneath a narrow pore. The is hidden by a whitish thalline layer, and when abraded, it reveals brown to black fissured that form concentric layers in older specimens. Notably, a is absent in this genus. The of ''Cryptoschizotrema'' is , displaying a dark brown colour that may partially towar ...

Graphidaceae
The Graphidaceae are a family of lichens in the order Ostropales. Distribution and ecology The vast majority of Graphidaceae species are restricted to the tropics. Most Graphidaceae species are epiphytic (i.e. they grow only on plants). Genera A recent (2020) estimates places 31 genera and about 990 species in Graphidaceae. The following list indicates the genus name, the taxonomic authority, year of publication, and the number of species: *''Acanthothecis'' – 5 spp. *''Acanthotrema'' – 1 sp. *''Aggregatorygma'' – 1 sp. *''Allographa'' – 183 spp. *''Amazonotrema'' – 1 sp. *'' Ampliotrema'' – 1 sp. *'' Anomalographis'' – 2 spp. *''Anomomorpha'' – 8 spp. *''Astrochapsa'' – 29 spp. *'' Austrotrema'' – 3 spp. *'' Borinquenotrema'' – 1 sp. *'' Byssotrema'' – 1 sp. *''Carbacanthographis'' – 22 spp. *''Chapsa'' – 51 spp. *''Chroodiscus'' – 17 spp. *'' Clandestinotrema'' – 17 spp. *'' Compositrema'' – 4 spp. *'' Corticorygma'' – 1 ...

Helge Thorsten Lumbsch
Helge Thorsten Lumbsch (born 1964) is a German-born lichenologist living in the United States. His research interests include the phylogeny, taxonomy, and phylogeography of lichen-forming fungi; lichen diversity; lichen chemistry and chemotaxonomy. He is the Associate Curator and Head of Cryptogams and Chair of the Department of Botany at the Field Museum of Natural History. Biography Lumbsch was born in Frankfurt in 1964. Interested in lichens already as a schoolboy, he studied natural sciences at the University of Marburg, under the tutelage of Aino Henssen. He received his diploma in 1989, with a dissertation titled ''Ontogenetisch-systematische Studien der Trapeliaceae und verwandter Familien (Lichenisierte Ascomyceten)'' ("Ontogenic-systematic studies of the Trapeliaceae and related families (lichenized ascomycetes"). After Henssen's retirement in 1990, he transferred to the University in Essen, where he worked on the ''Lecanora subfusca'' group in Australasia, a subje ...

Lichen Genera
A lichen ( , ) is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms
. University of California Museum of Paleontology.
Lichens have properties different from those of their component organisms. They come in many colors, sizes, and forms and are sometimes plant-like, but are not plants. They may have tiny, leafless branches ( fruticose); flat leaf-like structures ( foliose); grow crust ...
