The enigmatic Semimorula liquescens E.F. Haskins, McGuin. & C.S. Berry has been isolated repeatedly from dried infructescences of Lythrum salicaria collected from Seattle and Kirkland, Washington. Detailed developmental, morphological and ultrastructural studies suggested that it represents a taxon within Mycetozoa, closely allied with Myxogastria (Myxomycetes) but with unique characteristics. Phylogeny based on two genes places it with confidence in family Echinosteliidae. This species differs from a typical Echinostelium in the way spores germinate and in the lack of a stalked sporophore, the latter being a secondary loss. Semimorula liquescens therefore might be a useful negative model to search for genes inducing stalk formation during sporulation.
神秘的液化半孢黏菌（Semimorula liquescens）E.F. 哈斯金斯、麦奎因和C.S. 贝里多次从华盛顿州西雅图和柯克兰采集的千屈菜干燥果序中分离得到。详细的发育、形态和超微结构研究表明，它代表黏菌门内的一个分类单元，与黏菌纲（黏菌）密切相关，但具有独特特征。基于两个基因的系统发育分析将其可靠地置于刺丝黏菌科。该物种在孢子萌发方式以及缺乏有柄子实体方面与典型的刺丝黏菌不同，后者是次生缺失。因此，液化半孢黏菌可能是寻找在孢子形成过程中诱导柄形成的基因的有用阴性模型。
