Abstract: 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 Tarzetta 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.

Key words: ectomycorrhiza, morphology, anatomical structure, Pinus tabulaeformis
