A new species with remarkable morphology, Nectria eustromatica, is described, based on morphology of the teleomorph and anamorph, ecology and molecular phylogenetic analyses. Nectria eustromatica is characterized by sphaeroid perithecia immersed in pseudoparenchymatous stromata formed singly or collectively on a subiculum. Despite its deviating teleomorph morphology, it is placed within Nectria sensu stricto in phylogenetic analyses of a combined dataset of LSU, ITS, rpb2 and tef1 sequences with high internal support. Nectria eustromatica has been collected specifically on Hippocrepis (Coronilla) emerus in southern Europe. The anamorph of N. eustromatica shares morphological traits with the genera Stilbella and Tubercularia but produces non-phialidic macroconidia in addition to phialoconidia.
一种具有显著形态的新物种，即 eustromatica 属的 Nectria，是基于其同型态和异型态的形态、生态学和分子系统发育分析而被描述的。eustromatica 属的 Nectria 的特征是球形的子囊壳埋藏在假薄壁组织的基质中，单个或集体形成在基物上。尽管它的同型态形态有偏差，但在 LSU、ITS、rpb2 和 tef1 序列的联合数据集的系统发育分析中，它被置于严格意义上的 Nectria 中，具有高内部支持。eustromatica 属的 Nectria 专门在南欧的 Hippocrepis（Coronilla）emerus 上收集。eustromatica 属的异型态与 Stilbella 和 Tubercularia 属具有相似的形态特征，但除了产生瓶梗孢子外，还产生非瓶梗的大型孢子。
