摘　　要：对长白山地区黏菌区系进行初步研究,结果如下:含2 0种以上的大科有5个,分别为绒泡菌科、团毛菌科、钙皮菌科、发网菌科和筛菌科,共含195种,占总种数的92 .86 % ;含10种以上的属有绒泡菌属、团网菌属、筛菌属、双皮菌属、团毛菌属、钙皮菌属和发网菌属,共含14 4种,占总数的6 8.5 7%。从物种的区系成分上看,世界分布和北温带成分占绝对优势,二者占总种数的6 6 .6 6 %。另外,特有成分也较多。说明长白山黏菌区系丰富多彩并具有特色。The investigation on the Myxomycetes from Changbai Mountains indicates that there are 5 big families (Physaraceae, Trichiaceae, Didymiaceae, Stemonitaceae and Cribrariaceae)in this area, each of which includes more than 20 species. These 5 families have 195 species and occupy 92.86% of the total number of Myxomycetes from Jilin province. There are 7 big genera(Physarum,Arcyria, Cribraria, Diderma, Trichia, Didymium and Stemonitis), each of which contains more than 10 species. They include 144 species, which occupy 68.57% of all species. Regarding the composition, cosmopolitan and north temperate zone are the dominant distributional types. They occupy 66.66%. In addition, the abundant endemic composition indicates that the biota of Changbai Mountains is rich and distinctive.
