对日本西部落叶和常绿混交林中不同植被类型的不同叶凋落物上的粘菌群落进行了比较。共记录到33种粘菌，它们与森林枯枝落叶层自然条件下的化学和生物环境有关。在距优势树不远(300m)的不同地点，优势树下发现不同的粘菌组合。结果表明：1个立地的山李有21种，青栎树有20种，冬青树有12种，锯缘栎树有13种和14种。非度量多维尺度分析表明，黏菌群落与落叶乔木和常绿乔木的凋落物类型密切相关，凋落物pH和纤维分解活性均影响黏菌种类的分布。PH值较高的凋落物的物种丰富度高于酸性较高的凋落物。当地混交林中优势乔木凋落物和凋落物pH强烈影响叶生粘菌的种类分布。
Myxomycete assemblages were compared on various leaf litters of different vegetation types in a local mixed forest consisting of deciduous and evergreen trees in western Japan. A total of 33 myxomycete species were recorded and associated with the chemical and biological environments of leaf litters under natural condition of the forest floor. Different myxomycete assemblages were found on different sites under the dominant trees in a short distance apart (300 m). A site of Prunus jamasakura tree yielded 21 species, a Quercus glauca tree yielded 20 species, an Ilex pedunculosa tree yielded 12 species, and two Quercus serrata trees yielded 13 and 14 species, respectively. Non-metric multidimensional scaling demonstrated that the myxomycete assemblages were closely related to the litter types of deciduous and evergreen trees, and both litter pH and cellulolytic activity influenced distribution of myxomycete species. Species richness was higher in leaf litters with higher pH than in leaf litters with more acidic pH such as I. pedunculosa litter. The dominant tree litter and litter pH strongly influenced the species distribution of foliicolous myxomycetes in a local mixed forest.
