绒泡菌属黏菌一新种
A new species of Physarum(Myxomycetes)from China
摘要
Abstract
Physarum subgalbeum sp.nov.is described through observation of integrated morphological characterization and multigene phylogenetic analyses(nrSSU,mtSSU,α-Tub,and COI).The life cycle of P.subgalbeum was investigated in water agar medium and microscopic structure formation at different stages during sporulation was observed.This species is similar to P.galbeum in having golden yellow sporocarps.However,it differs in that its sporocarps often fuse into clusters,the spore surface is densely covered with small spines,and the lime nodes are elongated fusiform.Phylogenetic analysis results indicate that P.subgalbeum forms an independent monophyletic clade and constitutes a sister group relationship with P.galbeum.The spore germination of P.subgalbeum is split type,the plasmodial type is of phaneroplasmodium and sporulation requires approximately 10-12 hours,with lime nodes and capillitium forming prior to spore maturation.A comprehensive morphological description,including detailed micrographs,results of phylogenetic analyses,as well as a thorough account of its life cycle accompanied by corresponding microscopic images are provided.关键词
