对油松外生菌根的分支方式、颜色、大小、光泽,菌丝套的表面质地、菌丝组织结构、细胞大小、形状以及菌索、外延菌丝、囊状体等形态和解剖特征进行观察,共描述26种油松外生菌根的形态和解剖特征,其中包括17个担子菌、9个子囊菌,不同外生菌根的形态和解剖特征不同；首次描述一娄疣杯菌的外生菌根形态和解剖特征.结果表明:菌根的形态和解剖特征可以用于油松外生菌根真菌的种、属鉴定,而且随着不同外生菌根的形态和解剖结构特征数据资料的积累,形态鉴定将在外生菌根的生态学研究中发挥重要作用.%In this study, we observed and described morphological and anatomical characteristics of ectomycorrhizae associated with Pinus tabulaeformis. These characteristics include ectomycorrhizal ramification type, color, size and luster and anatomical features of mantles, such as surface texture, hyphal organization patterns, cell size and shape as well as the features of emanating hyphae, rhizomorphs and cystidia. The main results as following: 1 ) A total of 26 ectomycorrhizae had described, of which 17 were formed by basidiomycetes and nine were formed by ascomycytes. These ectomycorrhizae had different in morphological and anatomical features; 2) An ectomycorrhiza formed by Tarzetia sp. was for the first time described. This study indicated that morphological and anatomical characteristics can be used in - identifying P. tabulaeformis-ectomycorrhizae at species and generic level. Particularly, with the data accumulation of morphological and anatomical features, the morphological identification of ectomycorrhizae will pay an important role in ecological studies.
