Molecular insights into fungal diversity reveal three novel species of <i>Leucocoprinus</i> from southern Punjab, Pakistan

Three novel species of the genus <i>Leucocoprinus</i>, named <i>Lc. cinnamomeodiscus, Lc. dahranwalanus</i>, and <i>Lc. iqbalii</i>, are described from unexplored regions of southern Punjab, Pakistan, based on comprehensive analyses of morphoanatomical characteristics and molecular phylogenetic data. We provide illustrations of freshly collected basidiomata and detailed line drawings highlighting key anatomical features. The molecular phylogenetic analyses, which are based on the internal transcribed spacer (ITS) region and combined ITS-28S sequences, consistently position these newly described species within the genus <i>Leucocoprinus</i>. Additionally, this study also introduces new taxonomic combinations for previously reported <i>Leucoagaricus</i> species.本研究基于形态解剖学特征与分子系统发育数据的综合分析，对采自巴基斯坦旁遮普南部未开发区域的3个白鬼伞属（Leucocoprinus）新物种进行了描述，分别命名为Lc. cinnamomeodiscus、Lc. dahranwalanus及Lc. iqbalii。本研究附有新鲜采集的担子果（basidiomata）实物图，以及标注关键解剖特征的精细线条绘图。基于内部转录间隔区（ITS）及联合ITS-28S序列的分子系统发育分析，均将这三个新描述的物种稳定归入白鬼伞属（Leucocoprinus）的系统发育框架内。此外，本研究还为此前已报道的白鳞伞属（Leucoagaricus）物种提出了新的分类学组合。
