European species of the genus Dendrostoma (Erythrogloeaceae, Diaporthales) occurring on Castanea sativa and Quercus spp. based on freshly collected material are presented. Using a matrix of sequences from ITS, LSU, rpb2, and tef1, five species are recognized, and their phylogenetic positions are determined. Four species are added to the 14 described species of Dendrostoma. Dendrostoma atlanticum on Castanea sativa, D. creticum on Quercus coccifera and D. istriacum on Q. ilex are described as new species, Valsa castanea is combined in Dendrostoma, and D. leiphaemia is redescribed and illustrated. A key to the European species of Dendrostoma is provided.

欧洲种类的树突瘤（Diaporthales）。

欧洲树种（Dendrostoma）（Erythrogloeaceae，Diaporthales）出现在栗树和栎属上。介绍了基于新收集的材料。使用来自ITS，LSU，rpb2和tef1的序列矩阵，识别出五个物种，并确定了它们的系统发生位置。四个物种被添加到描述的14种树突动物中。在新品种中描述了栗树上的大西洋树突线虫，球果栎上的角皮线虫和冬青属上的角皮线虫，在树皮线虫中结合了Valsa castanea，并描述和说明了脂溢性线虫。提供了欧洲树突动物物种的钥匙。
