ABSTRACT Species of Endogonaceae (Endogonales, Mucoromycotina) are characterized by the formation of relatively large sporocarps and zygosporangia. Numerous species in this family remain undescribed or have unclear phylogenetic positions. In Asia specifically, the species diversity of this family is almost completely unknown. However, many mycobionts of bryophytes belonging to several novel clades in Endogonaceae have recently been identified phylogenetically. Therefore, establishing a robust taxonomic system for this family is essential. We obtained numerous sporocarps of undescribed Endogonaceae-like species from the Japanese islands. Morphological observation and multilocus phylogenetic analysis of nuc 18S rDNA (18S), nuc 28S rDNA (28S), and portions of two nuclear protein-coding regions—translation elongation factor 1-alpha (tef1) and RNA polymerase II large subunit (rpb1)—from these species resulted in the description of one new species each of Endogone and Jimgerdemannia and two new species of Vinositunica, gen. nov. Because Vinositunica is characterized by purplish sporocarps and red-wine-colored chlamydospores up to 700 μm in diameter, we emended the definition of Endogonaceae.

日本岛屿内多根科的分类学研究：内多根新种、Jimgerdemannia 和 Vinositunica，gen。十一月

摘要 Endogonaceae (Endogonales, Mucoromycotina) 的特征是形成相对较大的孢子果和接合孢子囊。该家族中的许多物种仍未被描述或具有不清楚的系统发育位置。特别是在亚洲，该科的物种多样性几乎完全未知。然而，最近在系统发育上鉴定了属于 Endogonaceae 中几个新进化枝的苔藓植物的许多分枝杆菌。因此，为这个科建立一个强大的分类系统是必不可少的。我们从日本岛屿获得了许多未描述的类似内根科植物的孢子果。nuc 18S rDNA (18S)、nuc 28S rDNA (28S)、以及来自这些物种的两个核蛋白编码区——翻译延伸因子 1-α (tef1) 和 RNA 聚合酶 II 大亚基 (rpb1) 的一部分，导致对 Endogone 和 Jimgerdemannia 各一个新物种和两个新物种的描述Vinositunica, gen. 十一月 因为 Vinositunica 的特征是紫色的孢子果和直径达 700 μm 的红酒色厚壁孢子，我们修改了 Endogonaceae 的定义。
