Diplomitoporus rimosus is a white rot polypore widely distributed in western N America, collected once in Africa, and is reported here from Iran. Molecular phylogenetic analyses of partial nuclear ribosomal LSU and ITS revealed that, unlike the generic type D. flavescens nested within the polyporoid clade, D. rimosus is positioned in the hymenochaetoid clade. A new genus is introduced to accommodate the species. Cyanotrama gen. nov. is recognized by its resupinate habit, narrow and strongly cyanophilous skeletal hyphae, barrel-shaped to short clavate basidia, variable presence of hyphal pegs and growth on conifers, especially Juniperus. Comparisons are made with representatives of polypores having similar morphological characteristics especially with cyanophilous skeletals. The biogeography of Cyanotrama rimosa with regard to its association with Juniperus woodlands is discussed briefly.
裂孔栓菌是一种广泛分布于北美西部的白腐多孔菌，曾在非洲被采集到一次，现被报道来自伊朗。基于核核糖体 LSU 和 ITS 部分序列的分子系统发育分析表明，与被归入多孔菌亚科的模式种 D. flavescens 不同，裂孔栓菌位于栓菌亚科。因此，引入了一个新属来容纳该种。蓝孔菌属（Cyanotrama）因其平伏生长、狭窄且强烈嗜蓝的骨架菌丝、桶形到短棒状的basidia、菌丝钉的存在与否以及在针叶树，特别是 Juniperus 上生长而被识别。与具有相似形态特征的多孔菌代表种进行了比较，特别是与嗜蓝骨架的多孔菌代表种。简要讨论了与 Juniperus 林地相关的蓝孔菌 rimosa 的生物地理学。
