The complex includes fungi with similar morphologies but which are thought to represent different species. The lack of available type material and associated absence of multiple locus sequence data has complicated identification of these fungi. The aim of this study was to clarify the identity of the laccate species occurring in Finland by inferring a phylogeny using DNA sequences from available boreal-temperate material. DNA from Finnish isolates together with an older isolate originating from the United Kingdom was sequenced, and the morphological features of the Finnish specimens were examined. The phylogenetic analysis of the internal transcribed spacer region (ITS), the elongation factor 1-α (), RNA polymerase II subunit (), and partial β-tubulin () genes revealed that the isolate from the United Kingdom did not fall within a well-supported clade with other sequences or related species. The Finnish isolates were closely related to the lineage in , and phylogenies. However, appears morphologically distinct from the Finnish material. The results suggest that , or a species phylogenetically closely related to it, may occur in Finland. But further investigation into the relationship between and from Europe will be needed to clarify the identity of the laccate species in Finland.
该复合体包括形态相似但被认为代表不同物种的真菌。由于缺乏可用的模式材料和相关的多个基因座序列数据，这些真菌的鉴定变得复杂。本研究的目的是通过使用来自可用的北方温带材料的 DNA 序列推断系统发育来阐明在芬兰发生的漆斑菌物种的身份。对来自芬兰的分离株的 DNA 进行测序，并与来自英国的较老的分离株一起进行测序，同时还检查了芬兰标本的形态特征。对内部转录间隔区 (ITS)、延伸因子 1-α ()、RNA 聚合酶 II 亚基 ()和部分β-微管蛋白 ()基因的系统发育分析表明，来自英国的分离株并未与其他漆斑菌序列或相关物种形成一个支持度良好的分支。芬兰的分离株与 和 谱系中的 密切相关。然而， 在形态上与芬兰的材料明显不同。结果表明， 或与其在系统发育上密切相关的物种可能在芬兰存在。但是，需要进一步调查欧洲的 和 之间的关系，以阐明芬兰漆斑菌物种的身份。
