In 2004, the family Micareaceae included the genera; Helocarpon, Micarea, Psilolechia, Roccellinastrum, and Scutula.[4] Then in 2005, molecular phylogeny based on mitochondrial rDNA sequences showed that the genus Helocarpon was not related to the Micareaceae family and the rest of the genus were related to the Pilocarpaceae family and other genera.[5]
Description
Pilocarpaceae species are crustose and have ascomata in the form of an brightly-coloured apothecium with a poorly-developed margin comprising loosely-intertwined hyphae. The ascospores are hyaline and often elongated with one or more septa.[2]
Genera
Pilocarpaceae contains 32 genera and an estimated 445 species. The following list shows the genera, authority, year of publication, and number of species as of 2020[6] (unless a newer source is cited).
