Fungi are one of the most diverse groups of organisms on Earth, amongst which wood-inhabiting fungi play a crucial role in ecosystem processes and functions. Four new wood-inhabiting fungi, , , and are proposed, based on morphological features and molecular evidence. is distinguished by a cream hymenial surface with a pruinose hymenophore, a monomitic hyphal system with clamped generative hyphae and ellipsoid basidiospores. is characterised by flavescens hymenophore surface with odontioid hymenophore, monomitic hyphal system with clamped generative hyphae and ellipsoid basidiospores. bears coriaceous basidiomata with a poroid hymenophore surface, monomitic hyphal system with clamped generative hyphae and ellipsoid basidiospores. is a distinct taxon by its grandinoid hymenophore surface, monomitic hyphal system with clamped generative hyphae and ellipsoid basidiospores. Sequences of ITS and nLSU rRNA markers of the studied samples were generated and phylogenetic analyses were performed using the Maximum Likelihood, Maximum Parsimony, and Bayesian Inference methods. The phylogram, based on the ITS+nLSU rDNA gene regions, included three genera within the Schizoporaceae as , and . The four new species were grouped into the genus . The topology, based on the ITS sequences, revealed that was grouped closely with , and . The taxon was sister to . The species separated from , while was grouped with four taxa: , , and .
真菌是地球上生物多样性最为丰富的类群之一，其中木生真菌在生态系统过程和功能中发挥着关键作用。基于形态特征和分子证据，提出了四种新的木生真菌，即[具体名称1]、[具体名称2]、[具体名称3]和[具体名称4]。[具体名称1]的特征为菌褶表面呈奶油色，菌褶具粉霜，单系菌丝系统，有锁状联合的生殖菌丝，以及椭圆形担孢子。[具体名称2]的特征为菌褶表面浅黄色，具齿状菌褶，单系菌丝系统，有锁状联合的生殖菌丝，以及椭圆形担孢子。[具体名称3]具有革质担子果，菌褶表面具小孔，单系菌丝系统，有锁状联合的生殖菌丝，以及椭圆形担孢子。[具体名称4]因其具大孔状菌褶表面、单系菌丝系统、有锁状联合的生殖菌丝和椭圆形担孢子而成为一个独特的分类单元。对所研究样本的ITS和nLSU rRNA标记序列进行了测定，并使用最大似然法、最大简约法和贝叶斯推断法进行了系统发育分析。基于ITS + nLSU rDNA基因区域的系统发育树包括裂褶菌科内的三个属，即[属名1]、[属名2]和[属名3]。这四个新物种被归入[属名4]属。基于ITS序列的拓扑结构显示，[具体名称1]与[具体名称5]、[具体名称6]和[具体名称7]紧密聚类。分类单元[具体名称8]是[具体名称9]的姊妹类群。[具体名称10]物种与[具体名称11]分开，而[具体名称12]与四个分类单元聚类在一起，即[具体名称13]、[具体名称14]、[具体名称15]和[具体名称16]。
