Diploschistes

Diploschistes (crater lichen) is a genus of lichen-forming fungi in the family Graphidaceae.[2] Members of the genus are crustose lichens with a thick, cracked (areolate) body (thallus) with worldwide distribution.[3]:264[4][5] The fruiting part (apothecia) are immersed in the thick thallus so as to have the appearance of being small "craters".[3]:264 The widespread genus contains about 43 species.[6]

Taxonomy

Johannes Musæus Norman originally circumscribed the genus in 1853.[7] It is in the family Graphidaceae. In 2018,[8] Kraichak and colleagues, using a "temporal phylogenetic" approach to identify temporal bands for specific taxonomic ranks, proposed placing Diploschistes as the type genus of Diploschistaceae, a family originally proposed by Zalbruckner in 1905.[9] This taxonomic proposal was rejected by Robert Lücking in a critical 2019 review of the temporal method for the classification of lichen-forming fungi, using this specific example to highlight several drawbacks of this approach.[10]
