Abstract
Thegenus Podaxis was first described from India by Linnaeus in 1771, but several revisions of the genus have left the taxonomy unclear. Forty-four Podaxis species names and nine intraspecific varieties are currently accepted, but most fungarium specimens are labelled Podaxis pistillaris. Recent molecular analyses based on barcoding genes suggest that the genus comprises severals pecies, but their status is largely unresolved. Here we obtained basidiospores and photographs from166 fungarium specimens from around the world and generated a phylogeny basedonr
DNA internal transcribed spacer ITS1, 5.8S and ITS2(ITS), and aphylogenomic analysis of 3839 BUSCO genes from low-coverage genomes for a subset of the specimens. Combining phylogenetics, phylogenomics, morphology, ecology, and geographical distribution, spanning 250 years of collections, we
propose that the genus includes at least 16 unambiguous species. Based on10 type specimens (holotype, paratype, andsyntype), four recorded species were confirmed, P. carcinomalis, P. deflersii, P. emerici, and P. farlowii. Comparing phylogenetic analysis with described
species, including morphology, ecology, and distribution, we resurrected P. termitophilus and designated neotypes, epitypes, orlectotypes for five previously described species, P. aegyptiacus, P. africana, P. beringamensis, P. calyptratus and P. perraldieri.
Lastly, based on phylogenies and morphology of type material, we synonymized three reported species, P. algericus, P. arabicus, and P. rugospora with P. pistillaris, and described five newspecies that we named P. desolatus, P. inyoensis, P. mareebaensis, P. namaquensis, and P. namibensis.
期刊介绍:
Persoonia aspires to publish papers focusing on the molecular systematics and evolution of fungi. Additionally, it seeks to advance fungal taxonomy by employing a polythetic approach to elucidate the genuine phylogeny and relationships within the kingdom Fungi. The journal is dedicated to disseminating high-quality papers that unravel both known and novel fungal taxa at the DNA level. Moreover, it endeavors to provide fresh insights into evolutionary processes and relationships. The scope of papers considered encompasses research articles, along with topical and book reviews.
