Abstract
Ectomycorrhizal (ECM) trees were commonly distributed in subtropical forest ecosystems, but we know little of below-ground ECM status. The ECM community composition and anatomical structure of Castanopsis fargesii were investigated in a subtropical evergreen broad-leaved forest of southwest China. Twelve root samples of C. fargesii were collected from a 2-ha plot and a total of 19 ECM morphotypes were obtained based on morphological characters. Furthermore, a total of 17 ECM fungi were identified from the 19 morphotypes based on the analysis of ITS sequences. Of these fungi, 14 belonged to Basidiomycetes and 3 were Ascomycetes. Taxa in Russulaceae and Thelephoraceae were frequent. Lactarius sp., Russula sp.1, Tomentella sp.2 and Boletus sp. were the dominant fungi occurred in more than four samples with importance values of 31.5, 29.4, 23.4 and 22.9%, respectively. The other 13 ECM fungi were rare. Anatomical structures of the 17 ECMs were described. This is the first study to characterize the below-ground ECM communities and anatomical structures in a subtropical evergreen broad-leaved forest.
