We evaluated the inclusion of a cryptic species in a Japanese population. We sampled specimens under various vegetation and climate conditions, and then conducted phylogenetic analyses on sequences from seven loci. The specimens showed two distinct groups, except when the ITS phylogeny was considered. These two phylogroups showed different distributions: subalpine-cool temperate and temperate-subtropical areas. Although these two phylogroups overlapped in terms of basidiospore size, the latter tended to exhibit smaller basidiospores. In addition, only the former showed mycelial growth on nutrient agar. Based on these phylo-morpho-ecophysiological characteristics, we separated the specimens labeled with the name into two species. As the lectotype of showed similarity to the former by DNA analysis, the latter was described as a new species, namely . Based on the geographic patterns of the two species, may have invaded the natural habit of because of global warming.
我们评估了一个隐存物种在日本种群中的情况。我们在各种植被和气候条件下采集标本，然后对来自七个基因座的序列进行系统发育分析。除了考虑ITS系统发育时，标本显示出两个不同的组。这两个系统发育组表现出不同的分布：亚高山 - 凉爽温带和温带 - 亚热带地区。尽管这两个系统发育组在担孢子大小方面有重叠，但后者倾向于表现出较小的担孢子。此外，只有前者在营养琼脂上表现出菌丝生长。基于这些系统发育 - 形态 - 生态生理特征，我们将标有该名称的标本分为两个物种。由于DNA分析显示模式标本与前者相似，后者被描述为一个新物种，即 。基于这两个物种的地理分布模式， 可能由于全球变暖而侵入了 的自然栖息地。
