English: Texosporium lichen
Texosporium is a genus of lichenized fungi in the family Caliciaceae.[1] It is a monotypic genus, containing the single species Texosporium sancti-jacobi, found in the United States. The genus is characterized by microscopic features: the ascospores are coated with a layer of cells that are derived from the paraphyses. Texosporium was originally circumscribed by Josef Nádvorník in 1942,[2] albeit the name was not validly published. In 1968, Leif Tibell and Angelica van Hofsten published the name validly.[3] In 2020, Texosporium sancti-jacobi was added to the global IUCN Red List, where it is classified as endangered.[4]
