摘要
在对巴基斯坦湿润温带森林进行蘑菇调查期间（2017 年至 2022 年），发现了五个不同的 Hydnum 采集标本。对这些标本的内部转录间隔（nrITS）进行形态解剖学和系统发生学分析后，发现了一个科学新种（Hydnum khanspurense sp.nov.）和一个巴基斯坦新记录（Hydnum berkeleyanum）。Hydnum khanspurense sp. nov.的特点是无下延刺，基生孢子相对较小，基生体具 1-4 个立体位点，ITS 区域与 Pallida 亚属的近缘种 H. pallidomarginatum 和 H. flabellatum 存在差异。同样，根据显微形态学和系统发生学分析，首次在巴基斯坦确认了 H. berkeleyanum，它是 Hydnum 亚属的一个成员。详细的系统发育分析确认了这些分类群的系统位置，并提供了形态解剖学研究和图解。
Hydnum khanspurense sp. nov. and H. berkeleyanum from Pakistan
During mushroom surveys (2017 to 2022) of moist temperate forests of Pakistan, five different collections of Hydnum were found. Morpho-anatomical and phylogenetic analysis of the internal transcribed spacer (nrITS) of these specimens revealed one species new to science (Hydnum khanspurense sp. nov.) and one new record for Pakistan (Hydnum berkeleyanum). Hydnum khanspurense sp. nov. is characterized by non-decurrent spines, relatively smaller basidiospores and basidia with 1–4 sterigmata, along with ITS region divergence from the closest related species of subgenus Pallida, H. pallidomarginatum and H. flabellatum. Similarly, H. berkeleyanum, a member of subgenus Hydnum, was confirmed for the first time in Pakistan on the basis of micro-morphological and phylogenetic analysis. Detailed phylogenetic analysis confirming their systematic positions and morpho-anatomical studies of these taxa are provided and illustrated.
期刊介绍：
Phytotaxa is a peer-reviewed, international journal for rapid publication of high quality papers on any aspect of systematic and taxonomic botany, with a preference for large taxonomic works such as monographs, floras, revisions and evolutionary studies and descriptions of new taxa. Phytotaxa covers all groups covered by the International Code of Nomenclature foralgae, fungi, and plants ICNafp (fungi, lichens, algae, diatoms, mosses, liverworts, hornworts, and vascular plants), both living and fossil. Phytotaxa was founded in 2009 as botanical sister journal to Zootaxa. It has a large editorial board, who are running this journal on a voluntary basis, and it is published by Magnolia Press (Auckland , New Zealand). It is also indexed by SCIE, JCR and Biosis.
All types of taxonomic, floristic and phytogeographic papers are considered, including theoretical papers and methodology, systematics and phylogeny, monographs, revisions and reviews, catalogues, biographies and bibliographies, history of botanical explorations, identification guides, floras, analyses of characters, phylogenetic studies and phytogeography, descriptions of taxa, typification and nomenclatural papers. Monographs and other long manuscripts (of 60 printed pages or more) can be published as books, which will receive an ISBN number as well as being part of the Phytotaxa series.
