Based on molecular phylogenetic analyses of a multigene matrix of partial nuSSU-ITS-LSU rDNA, cal, his, ms204, rpb1, rpb2, tef1 and tub2 sequences, recent European and Iranian collections of Melanconium pterocaryae from the type host, Pterocarya fraxinifolia, are shown to be distinct from the Japanese Melanconis pterocaryae from Pterocarya rhoifolia, and both are confirmed as closely related members of the recently described genus Juglanconis. Therefore, the new name Juglanconis japonica is proposed for Melanconis pterocaryae. As no type collection could be traced, Melanconium pterocaryae (syn. J. pterocaryae) is neotypified, described and illustrated, and it is recorded for Europe for the first time. During field surveys in natural stands of P. fraxinifolia in Guilan province (Iran), Juglanconis pterocaryae was consistently isolated from tissues affected by branch and trunk cankers, twig dieback and wood necrosis, indicating that it is the causal agent of these diseases. The external and internal symptoms associated with these trunk diseases are described and illustrated.

翼龙属的Juglanconis(Diaporthales)属。

基于局部nuSSU-ITS-LSU rDNA序列的多基因矩阵的分子系统发育分析,CAL他的ms204RPB1RPB2TEF1TUB2序列,近期欧洲和伊朗的收藏Melanconium pterocaryae从类型主机,枫杨fraxinifolia,是示出为从日本人不同Melanconis pterocaryae水胡桃,并且两者都确认为最近描述属密切相关的成员Juglanconis。因此,建议将新名称Juglanconis japonica用于黑色素伞菌。由于无法找到任何类型的馆藏,因此对翼龙黑伞S. J. pterocaryae)进行了新类型化,描述和说明,并首次在欧洲进行了记录。在对桂兰省(伊朗)的fraxinifolia天然林中进行实地调查时,从受分支和树干溃疡,树枝枯死和木材坏死影响的组织中始终分离出胡桃果蕨,这表明它们是这些疾病的诱因。描述和说明了与这些躯干疾病相关的外部和内部症状。
