Stipitate stereoid fungi are Basidiomycetes with a stipe, a spathulate-to funnel-shaped pileus, a smooth hymenophore, and hyaline, smooth spores. Representatives of the genera Cotylidia, Cymatoderma, Muscinupta, Podoscypha and Stereopsis were subjected to molecular phylogenetic analyses based on nuclear ribosomal large subunit, 5.8S and ITS sequences. For four of the genera the type species was included in analyses. Stereopsis radicans, the type species of Stereopsis, forms a lineage with the corticioid species Clavulicium globosum but could not be placed in any of the presently accepted orders within Agaricomycotina. Stereopsis vitellina falls within the Atheliales, making it the first pileus- and stipe-forming fungus recovered in this order. Cotylidia and Muscinupta again are shown to be members of the Hymenochaetales, whereas Cymatoderma and Podoscypha belong in the Polyporales. Cymatoderma is polyphyletic and Cymatoderma sensu stricto is separated from other stipitate stereoid fungi in the Polyporales, whereas the remaining Cymatoderma species are nested within a well supported clade holding all Podoscypha species but also Abortiporus biennis.
柄层孔菌是一类具有柄、匙形至漏斗形菌盖、光滑的子实层和透明、光滑孢子的担子菌。基于核核糖体大亚基、5.8S 和 ITS 序列，对 Cotylidia、Cymatoderma、Muscinupta、Podoscypha 和 Stereopsis 属的代表种进行了分子系统发育分析。其中四个属的模式种被包括在分析中。Stereopsis radicans，即 Stereopsis 的模式种，与皮层状物种 Clavulicium globosum 形成一个谱系，但不能归入伞菌目中现有的任何一个目。Stereopsis vitellina 属于 Atheliales，这是该目中首次发现的有帽和柄的真菌。Cotylidia 和 Muscinupta 再次被证明是 Hymenochaetales 的成员，而 Cymatoderma 和 Podoscypha 属于 Polyporales。Cymatoderma 是多系的，Cymatoderma sensu stricto 与 Polyporales 中的其他柄层孔菌分离，而其余的 Cymatoderma 物种则嵌套在一个支持良好的分支中，该分支包含所有 Podoscypha 物种，但也包括 Abortiporus biennis。
