Hohenbuehelia longicolla sp. nov. (Pleurotaceae) from Swat, Pakistan, and two new country records

Hohenbuehelia Schulzer is a genus of nematode-trapping, pleurotoid fungi that grow on a variety of substrates in forest ecosystems. Despite its high species diversity and complexity, it remains taxonomically underexplored and unrevised. In this study, morphological and phylogenetic analyses were conducted to confirm the identification of Hohenbuehelia specimens collected during a mycological survey in the district Swat, Pakistan. The Hohenbuehelia filolageniformis S. Hussain is described as a new species, while H. tremula and H. wilhelmii are reported as new records to the country. H. filolageniformis is morphologically and phylogenetically well-differentiated from other species of the genus. This study contributes to the understanding of the global diversity and distribution of Hohenbuehelia in Pakistan.
