Ganoderma 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 Ganoderma spp. are medicinally active and therefore are used to treat human diseases or as a dietary supplement. In this study, three Ganoderma 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 Ganoderma. One strain was collected from Surat Thani Province clustered in the G. casuarinicola clade with high statistical support (MLBS = 100% / MPBS = 98% / PP = 0.96), while the other two strains of Ganoderma, 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. Ganoderma casuarinicola 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.

在泰国增加了对灵芝的了解：创纪录的灵芝casuarinicola；和灵芝thainicum sp。十一月

灵芝是一种世界性的蘑菇属，可引起许多树种的根腐病。该属的成员在热带地区特别多样化。一些灵芝。具有医学活性，因此可用于治疗人类疾病或作为膳食补充剂。在这项研究中，在泰国南部的热带地区收集了三种灵芝菌株。结合ITS，LSU，TEF1α和RPB2序列数据进行的系统进化分析表明，这三种菌株在乳酸盐灵芝内属于不同的谱系。其中一株是从素叻他尼省收集的，聚集在卡苏里尼科拉枝条中，具有较高的统计支持（MLBS = 100％/ MPBS = 98％/ PP = 0.96），而其他两株灵芝则是从那空是他玛叻省收集的，形成了独特的支撑良好的进化枝（MLBS = 100％/ MPBS = 100％/ PP = 1.00），在此被描述为新物种。据报道，灵芝casuarinicola是泰国的新纪录。讨论了两个分类单元及其密切相关的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的位置的系统树。
