Abstract：
Panus is a typical wood-rotting fungi, which plays considerable roles in ecosystems and has significant economic value. The genus Panus currently consists of more than 100 species; however, only eight species have been reported from China. This study aims to distinguish and describe two novel species from the Panussimilis complex, namely Panusminisporus and Panusbaishanzuensis, one new record species from Zhejiang Province, Panussimilis and three common species, Panusconchatus, Panusneostrigosus and Panusrudis, based on detailed morphological and phylogenetic studies, relying on Chinese specimens. Panusminisporus is characterised by its reddish-brown pileus, decurrent lamellae with cross-veins, slender stipe, smaller basidiospores, wider generative hyphae and absence of sclerocystidia. Panusbaishanzuensis is featured by its pileus with concentric and darker ring zone, decurrent lamellae with cross-veins, shorter stipe, longer basidiospores, diverse and shorter cheilocystidia and smaller sclerocystidia. Internal transcribed spacer (ITS) regions, large subunit nuclear ribosomal RNA gene (nLSU) and translation elongation factor 1-α gene (tef-1α) were employed to perform a thorough phylogenetic analysis for genus Panus and related genera, using Bayesian Inference and Maximum Likelihood analysis. The results indicate that Panusminisporus and Panusbaishanzuensis form two independent clades within the Panussimilis complex themselves. Detailed descriptions, taxonomic notes, illustrations etc. were provided. In addition, a key to the reported species of Panus from China is also provided.
摘要：
潘努斯是一种典型的木材腐烂真菌，在生态系统中起着相当重要的作用，具有显著的经济价值。Panus属目前由100多个物种组成；然而，据报道，中国只有8种。本研究旨在区分和描述Panussimilis复合体中的两个新物种，即番泻和番泻，一个来自浙江省的新记录物种，Panussimilis和三个常见物种，Panusconchatus,Panusneostrigosus和Panusrudis，基于详细的形态学和系统发育研究，依靠中国的标本。Panusminisporus的特征是其红棕色的绒毛，带交叉静脉的下流薄片，细长的刀柄，较小的担子孢子，更宽的生成菌丝和没有巩膜。番石榴的特点是其具有同心和较暗的环带的成堆，带交叉静脉的下流薄片，较短的刀柄，较长的担子孢子，多样和较短的鞘细胞和较小的巩膜细胞。内部转录间隔区（ITS）区域，采用大亚基核核糖体RNA基因（nLSU）和翻译延伸因子1-α基因（tef-1α）对Panus属及相关属进行了彻底的系统发育分析，使用贝叶斯推断和最大似然分析。结果表明，Panusminisporus和Panusbaishanzuensis在Panussimilis复合体内部形成两个独立的进化枝。详细说明,分类学注释，插图等。提供了。此外,还提供了中国报道的Panus物种的关键。
