Trypetheliaceae
The Trypetheliaceae are a family of mainly lichen-forming fungi in the order Trypetheliales. The family consists almost exclusively of corticolous (bark-dwelling), crustose lichens with an almost strictly tropical distribution. Taxonomy Trypetheliaceae was circumscribed by German botanist Franz Gerhard Eschweiler in 1824. His of the family was as follows (translated from Latin):"Thallus is crust-like. Apothecia are of varied shape, immersed in warts formed from the thallus's medullary substance." Eschweiler further notes that the family is almost exclusively found within the tropics. In his initial circumscription, he included the following genera: '' Arthonia'', '' Porothelium'', '' Medusula'', '' Ophthalmidium'', '' Trypethelium'', '' Astrothelium'', '' Glyphis'', '' Chiodecton'', and '' Conioloma''. The family Arthopyreniaceae was placed into synonymy with Trypetheliaceae, and its type genus, '' Arthopyrenia'', was transferred to Trypetheliaceae in 2021. Other synonyms of ...

Astrothelium
''Astrothelium'' is a large genus of corticolous (bark-dwelling) lichens in the family Trypetheliaceae. The genus is characterized by a corticate thallus and diverse ascomata structures, which can be simple, aggregated, or forming . ''Astrothelium'' is also notable for the walls of its ascomata, the so-called ' (i.e., tightly interwoven) arrangement of cells in these walls, and various forms of , transparent spores. Taxonomy The genus was circumscribed in 1824 by German botanist Franz Gerhard Eschweiler, with '' Astrothelium conicum'' assigned as the type species. Description The thallus, or the vegetative body of ''Astrothelium'', is , meaning it is covered by a protective . The ascomata, which are the fruiting bodies containing the reproductive spores, can appear in various forms such as simple, aggregated, or forming . These structures often differ in their composition and colour, and can be used as to distinguish between species. The ascomata can range from being immersed ...
