Resinicolous fungi constitute a heterogeneous assemblage of fungi that live on fresh and solidified plant resins. The genus includes, according to current knowledge, two species, and . In contrast to other resinicolous discomycetes, which are placed in genera also including non-resinicolous species, species only ever fruit on resin. The taxonomic classification of has proven to be difficult and currently the genus, provisionally and based only on morphological features, has been assigned to the (). In contrast, molecular studies have noted a possible affinity to the . Here we review the taxonomic placement of using sequence data from seven phylogenetically informative DNA regions including ribosomal (ITS, nucSSU, mtSSU, nucLSU) and protein-coding () regions. We combined available and new sequence data with sequences from major classes, especially and , and assembled three different taxon samplings in order to place the genus within the . Based on our data, none of the applied phylogenetic approaches (Bayesian Inference, Maximum Likelihood and Maximum Parsimony) supported the placement of in the or any other order in the . A placement of within the is similarly unsupported. Based on our data, forms an isolated and highly supported phylogenetic lineage within the "". From the results of our multilocus phylogenetic analyses we propose here a new class, order, and family, , and in the to accommodate the genus . The genetic variability within the newly proposed class suggests that it is a larger group that requires further infrageneric classification.
树脂生真菌是一类生活在新鲜和固化植物树脂上的真菌的异质组合。据目前所知，该属包括两个物种，即[物种名1]和[物种名2]。与其他树脂生盘菌不同，其他树脂生盘菌所属的属还包括非树脂生的物种，而[该属物种名]仅在树脂上结果。[该属物种名]的分类一直很困难，目前仅基于形态特征，该属被暂时归入[目名]（[目名英文缩写]）。相比之下，分子研究表明它可能与[另一目名]有亲缘关系。在这里，我们使用来自七个系统发育信息丰富的DNA区域的序列数据，包括核糖体（ITS、nucSSU、mtSSU、nucLSU）和蛋白质编码（[蛋白质编码区域名称]）区域，来回顾[该属物种名]的分类地位。我们将现有的和新的序列数据与主要[纲名]类群，特别是[类群名1]和[类群名2]的序列相结合，并组装了三种不同的分类群样本，以便将[该属物种名]属置于[纲名]内。基于我们的数据，所应用的系统发育方法（贝叶斯推断、最大似然法和最大简约法）均不支持将[该属物种名]置于[目名]或[纲名]中的任何其他目中。同样，也没有证据支持将[该属物种名]置于[另一目名]内。基于我们的数据，[该属物种名]在“[某类群名称]”中形成了一个孤立且得到高度支持的系统发育谱系。从我们多位点系统发育分析的结果来看，我们在此提议在[纲名]中设立一个新的纲、目和科，即[新纲名]、[新目名]和[新科名]，以容纳[该属物种名]属。新提议纲内的遗传变异性表明它是一个更大的类群，需要进一步进行属以下的分类。
