is a cosmopolitan genus of mushrooms, which can cause root and butt rot diseases on many tree species. Members of this genus are particularly diverse in tropical regions. Some spp. are medicinally active and therefore are used to treat human diseases or as a dietary supplement. In this study, three strains were collected in tropical southern Thailand. Phylogenetic analyses of combined ITS, LSU, TEF1α and RPB2 sequence data indicated that the three strains grouped in a distinct lineage within laccate . One strain was collected from Surat Thani Province clustered in the clade with high statistical support (MLBS = 100% / MPBS = 98% / PP = 0.96), while the other two strains of , collected from Nakhon Si Thammarat Province, formed a distinct well-supported clade (MLBS = 100% / MPBS = 100% / PP = 1.00) and are described here as a new species. is reported here as a new record to Thailand. Morphological differences of the two taxa and their closely related taxa are discussed. Colour photographs of macro and micro morphological characteristics and a phylogenetic tree to show the placement of the new record and new species are provided.
是一个世界性的蘑菇属，可在许多树种上引起根腐病和干基腐病。该属成员在热带地区特别多样。一些物种具有药用活性，因此被用于治疗人类疾病或作为膳食补充剂。在本研究中，从泰国南部热带地区收集了三株菌株。对ITS、LSU、TEF1α和RPB2序列数据进行联合系统发育分析表明，这三株菌株在具漆状的内聚为一个独特的谱系。从素叻他尼府收集的一株菌株聚集在分支中，具有较高的统计支持率（MLBS = 100% / MPBS = 98% / PP = 0.96），而从洛坤府收集的另外两株菌株形成了一个独特的、得到充分支持的分支（MLBS = 100% / MPBS = 100% / PP = 1.00），在此被描述为一个新物种。在此报道为泰国新记录。讨论了这两个分类单元及其近缘分类单元的形态差异。提供了宏观和微观形态特征的彩色照片以及显示新记录和新物种位置的系统发育树。
