The molecular phylogeny of Acarosporaceae with a focus on the recently proposed genus Polysporinopsis was investigated using maximum parsimony and Bayesian analyses, using nuITS-LSU and mtSSU rDNA sequence datasets. A well-supported monophyletic clade corresponding to Acarospora (including the type species A. schleicheri, A. fuscata, A. nitrophila, A. rugulosa, A. bullata, A. sinopica, A molybdina and A. peliscypha) was present in all analyses. Acarospora as currently delimited is not monophyletic; neither A. smaragdula nor A. badiofusca belongs to the genus in the restricted sense. Polysporinopsis, which comprises three species previously classified in Acarospora (P. sinopica-type species, P. smaragdula, and P. rugulosa) is not a monophyletic group separate from Acarospora s. str. Acarospora sinopica and A. smaragdula are not closely related; A. sinopica belongs to Acarospora s. str., but A. smaragdula is one of the most basal taxa currently known in Acarosporaceae.
利用最大简约法和贝叶斯分析法，使用核内转录间隔区-大亚基核糖体DNA（nuITS-LSU）和线粒体小亚基核糖体DNA（mtSSU）序列数据集，对以最近提出的多孢裂孔菌属（Polysporinopsis）为重点的裂孔菌科（Acarosporaceae）分子系统发育进行了研究。在所有分析中均出现了一个得到充分支持的单系分支，该分支对应于裂孔菌属（包括模式种施氏裂孔菌（A. schleicheri）、暗褐裂孔菌（A. fuscata）、嗜硝裂孔菌（A. nitrophila）、皱裂孔菌（A. rugulosa）、泡状裂孔菌（A. bullata）、中华裂孔菌（A. sinopica）、钼裂孔菌（A molybdina）和盘状裂孔菌（A. peliscypha））。目前界定的裂孔菌属不是单系的；翡翠裂孔菌（A. smaragdula）和暗褐裂孔菌（A. badiofusca）都不属于狭义的裂孔菌属。多孢裂孔菌属包含先前分类在裂孔菌属中的三个物种（中华多孢裂孔菌（P. sinopica）——模式种、翡翠多孢裂孔菌（P. smaragdula）和皱多孢裂孔菌（P. rugulosa）），它不是一个与狭义裂孔菌属分开的单系类群。中华裂孔菌和翡翠裂孔菌关系不密切；中华裂孔菌属于狭义裂孔菌属，但翡翠裂孔菌是目前已知的裂孔菌科中最基部的类群之一。
