Two new wood-inhabiting fungal species, and spp. nov., are proposed based on a combination of morphological features and molecular evidence. Sequences of internal transcribed spacer and large subunit region of nuculear ribosomal RNA gene of the studied samples were generated, and phylogenetic analyses were performed using maximum likelihood, maximum parsimony and bayesian inference methods. is characterized by an annual growth habit, stipitate basidiocarps with scarlet to red, odontioid hymenial surface, a dimitic hyphal system with clamped generative hyphae negative in Melzer's reaction, and acyanophilous basidiospores measuring 2.5-3.5 × 1.5-2.5 µm. is distinguished by resupinate basidiomata with odontioid hymenial surface, a dimitic hyphal system with clamped generative hyphae, strongly encrusted cystidia and ellipsoid, hyaline, thin-walled, smooth basidiospores (3.5-4.5 × 2-3.5 µm). The phylogenetic analyses comfirmed that two new species nest in , in the residual polyporoid clade.
基于形态特征和分子证据,提出了两个新的木生真菌物种,即[物种名1]和[物种名2]新种。生成了所研究样本的核糖体核糖核酸基因内部转录间隔区和大亚基区域的序列,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。[物种名1]的特征是一年生习性,具柄的担子果,表面猩红色至红色,齿状子实层,双核菌丝系统,其中具锁状联合的生殖菌丝在Melzer试剂反应中呈阴性,以及嗜蓝性担孢子,大小为2.5 - 3.5×1.5 - 2.5 µm。[物种名2]的特征是平伏的担子果,具齿状子实层,双核菌丝系统,具锁状联合的生殖菌丝,强烈结壳的囊状体和椭圆形、透明、薄壁、光滑的担孢子(3.5 - 4.5×2 - 3.5 µm)。系统发育分析证实,这两个新物种嵌套在残余多孔菌分支中的[某属名]中。
