Species of the wood-decay genus Phylloporia (Hymenochaetaceae, Hymenochaetales, Basidiomycota) are widely distributed in the tropics. Phylloporia species are, however, morphologically and ecologically diverse, which makes morphology-based species identification challenging. In this study, we re-examined species of Phylloporia reported from Benin (West Africa). Using an integrative approach combining morphology, ecology, and phylogenetic analyses, we describe Phylloporia beninensis sp. nov. and report Phylloporia littoralis for the first time outside of its type locality. Phylloporia beninensis sp. nov. is characterized by its annual and imbricate basidiomata, duplex context with a black zone separating the upper context from the lower one, dimitic hyphal system, presence of cystidioles, basidia of 9-12 × 4-5 μm, and subglobose to ellipsoid basidiospores measuring 3-4.6 × 2.1-3.6 μm. Detailed descriptions with illustrations for the new species are provided. With the addition of the new species, 15 Phylloporia species are now known to occur in tropical Africa. Our discovery of a new Phylloporia species in Benin should stimulate further mycological investigations in tropical African ecosystems to discover other new polypore species. To facilitate further taxonomy studies on tropical African Phylloporia taxa, a key to the known tropical African species is provided.
木质腐朽属 Phylloporia（层孔菌科，层孔菌目，担子菌门）的物种广泛分布于热带地区。然而，Phylloporia 物种在形态和生态上具有多样性，这使得基于形态的物种鉴定具有挑战性。在本研究中，我们重新检查了来自贝宁（西非）的 Phylloporia 物种。我们采用结合形态学、生态学和系统发育分析的综合方法，描述了新种 Phylloporia beninensis sp. nov.，并首次在其模式产地以外报道了 Phylloporia littoralis。Phylloporia beninensis sp. nov. 的特征为一年生、覆瓦状的担子果，双层结构，黑色区域将上层与下层分开，双核菌丝系统，存在囊状体，担子 9-12×4-5μm，球形至椭圆形的担孢子 3-4.6×2.1-3.6μm。提供了新种的详细描述和插图。随着新种的加入，现在已知有 15 种 Phylloporia 物种分布在热带非洲。我们在贝宁发现的新 Phylloporia 物种应刺激对热带非洲生态系统的进一步真菌学调查，以发现其他新的多孔菌物种。为了便于进一步对热带非洲 Phylloporia 分类群进行分类学研究，提供了已知热带非洲物种的关键特征。
