In this study, we describe Pseudomegasporoporia margallensis as a novel species and report Microporellus subadustus as a new record from Pakistan based on morphology and phylogeny. Both genera are firstly reported in the country. Pseudomegasporoporia margallensis sp. nov. is characterized by light brownish gray poroid hymenphore, grayish brown subiculum surface, frequent generative hyphae in the subiculum with abundant clamp connections, and arboriform-branched skeletal hyphae in subiculum and tubes, and it forms a sister lineage of P. nerricola in the phylogeny. This novel taxon, showing 37 nucleotide differences in ITS nrDNA and 10 in LSU nrLSU sequences from P. nerricola, has GenBank accession numbers PP702233, PP702234, PP702235, PP702236, and PP70223, and is registered under MycoBank no. MB853645. This higlights the genetic distinction and importance of molecular identification in fungal taxonomy. The new species and the new record are described with detail illustrations.
在这项研究中，我们描述了 Pseudomegasporoporia margallensis 作为一个新种，并根据形态和系统发育将 Microporellus subadustus 报告为巴基斯坦的一个新记录。这两个属均为首次在该国报道。Pseudomegasporoporia margallensis sp. nov. 的特征是浅棕灰色的多孔子实层，灰棕色的下皮层表面，下皮层中频繁出现具有丰富夹子连接的生殖菌丝，以及在下皮层和管中呈树状分支的骨架菌丝，它在系统发育中与 P. nerricola 形成姐妹谱系。这个新分类群在 ITS nrDNA 中有 37 个核苷酸差异，在 LSU nrLSU 序列中有 10 个差异，与 P. nerricola 相比，其拥有 GenBank 登录号 PP702233、PP702234、PP702235、PP702236 和 PP70223，并在 MycoBank 注册为 MB853645。这突显了分子鉴定在真菌分类学中的遗传差异和重要性。详细描述了新种和新记录。
