(Hydnaceae, Basidiomycota) exhibits endemic species diversity in East Asia; however, few comprehensive systematic studies have been conducted to date. Here, we performed morphological, ecological, phylogenetic, and biological evaluations of the taxonomy of species in Japan. In total, 186 Japanese specimens were used for morphological observations. Phylogenetic trees were constructed using sequence data of nuc rDNA internal transcribed spacer ITS1-5.8S-ITS2 (ITS) region and a portion of translation elongation factor 1-α (). Intra- and interspecific mating tests using 78 monokaryotic strains of 13 species did not conflict with species delimitation inferred from their ITS and phylogenetic relationships. This study provides detailed morphological descriptions of 15 rigorously identified species from Japan, nine of which are described as new: , and . Three species documented in this work are new to Japan: , and . The remaining three species (, and ), previously reported from Japan, are redescribed using data from newly collected materials. We also transferred two old species ( and ) from East Asian into other genera.
（Hydnaceae，担子菌门）在东亚表现出特有物种多样性；然而，迄今为止，很少有全面的系统研究。在这里，我们对日本的物种分类进行了形态学、生态学、系统发育和生物学评估。共使用了 186 个日本标本进行形态观察。使用核 rDNA 内转录间隔区 ITS1-5.8S-ITS2（ITS）区域和翻译延伸因子 1-α（）部分序列数据构建了系统发育树。使用来自 13 个物种的 78 个单核菌株进行的种内和种间交配试验与从 ITS 和 系统发育关系推断的物种划分没有冲突。本研究提供了来自日本的 15 种严格鉴定的物种的详细形态描述，其中 9 种被描述为新种：、、、、、、、、和 。本研究记录的三个物种在日本是新记录种：、和 。以前从日本报道的其余三个物种（、和 ），使用新采集的材料重新描述。我们还将两个旧种（和 ）从东亚的 属转移到其他属中。
