Cyttaria是一个形态和生物学上不同的属，包括木材栖息物种，这些物种是南美洲南部，澳大利亚和新西兰的Nothofagus sensu stricto和Lophozonia属树木的生物营养伙伴。由于其子实体和生境的独特性，分类学家们将其归类于纤丝菌纲（Leotiomycetes）的胞囊藻目（Cyttariales）。一个多位点的系统发育重建Leotiomycetes类纳入新的序列数据从黑浆细胞表明Cyttariaceae有一个孤立的位置附近的基地Helotiales，弱支持的关系与Polydesmia pruinosa（incertae sedis）和Chlorociboriaceae。在此建议将Cyttariales作为Helotiales的异名。
Cyttaria is a morphologically and biologically distinct genus comprising wood-inhabiting species that are biotrophic associates of trees in the genera Nothofagus sensu stricto and Lophozonia in southern South America, Australia, and New Zealand. The uniqueness of the fruit bodies and habitat of Cyttaria has led taxonomists to justify its placement in its own order, Cyttariales, in Leotiomycetes. A multilocus phylogenetic reconstruction of the class Leotiomycetes incorporating new sequence data from Cyttaria nigra shows Cyttariaceae to have an isolated position near the base of Helotiales, with weak support for a relationship with Polydesmia pruinosa (incertae sedis) and Chlorociboriaceae. Cyttariales is here proposed as a synonym of Helotiales.
