A DNA-based checklist of the stipitate hydnoids (<i>Bankeraceae</i> s.l.) of Czechia.

Based on a long tradition of field research aimed at this group, stipitate hydnoid fungi belong to the best explored macromycetes in Czechia. However, following groundbreaking taxonomic changes emerging from recent molecular studies, previous knowledge of particular taxa and their features has been questioned. To resolve this issue, selected specimens of Czech hydnoids were sequenced to confirm their identity. Generally, the presence of 39 taxa of Boletopsis , Hydnellum , Phellodon , and Sarcodon in the Czech Republic was confirmed, including the recently described species Boletopsis mediterraneensis , Hydnellum bomiense , H. fagiscabrosum , H. rubidofuscum , Phellodon aquiloniniger , P. castaneoleucus , and two so far undescribed taxa of Boletopsis and Hydnellum , as well as the recently reported Hydnellum gracilipes , H. illudens , Phellodon secretus and Sarcodon quercinofibulatus . Ecological requirements of newly delimited species are specified based on collection data from Czech localities, and GlobalFungi data are presented to supplement the current knowledge of the global distribution of particular species. Taxonomic issues, identification limits in species complexes, ecology, and threats to the species are discussed in relevant cases. Several more species, documented from or probably present in Czechia but not sequenced yet, are commented as well.
