A new species of Orbilia related to O. luteorubella is described mainly based on morphological characters of its asexual morph and molecular data. The sexual morph does not significantly differ from O. luteorubella, whereas the asexual morph obtained from its ascospore isolate resembles members of the non-predacious genus Dactylella, because it has fusiform phragmoconidia borne singly at the apex of conidiophores. Phylogenetic analysis showed that this strain clustered with a clade that included available strains of the O. luteorubella aggregate and was distant from all analysed Dactylella species. Within this clade, the new strain fell between species with filiform conidia and those of a Pseudotripoconidium anamorph. By combining morphological and phylogenetic analyses, we conclude that our isolate belongs to a new taxon. Pleomorphism of the new taxon is described and discussed.
主要基于其无性型的形态特征和分子数据，描述了一种与黄红胶盘菌相关的新胶盘菌属物种。有性型与黄红胶盘菌没有显著差异，而从其子囊孢子分离物获得的无性型类似于非捕食性的指梗霉属成员，因为它有梭形的隔膜分生孢子，单个着生于分生孢子梗顶端。系统发育分析表明，该菌株与一个包含黄红胶盘菌聚集体可用菌株的分支聚类，并且与所有分析的指梗霉属物种距离较远。在这个分支内，新菌株位于具有丝状分生孢子的物种和具有拟三叉分生孢子无性型的物种之间。通过结合形态学和系统发育分析，我们得出结论，我们的分离物属于一个新的分类单元。描述并讨论了新分类单元的多型性。
