摘　　要：柳杉(Cryptomeria japonica var.sinensis Miquel),别名长叶孔雀松,是杉科(Taxodiaceae Warming)柳杉属(Cryptomeria D.Don)的一种常绿乔木。其树干高大,材质轻软,可供房屋建筑、家具等使用,此外,柳杉也是优美的园林树种[1]。目前,长江流域以南至广东、福建、贵州等地区均有栽培种植柳杉。但随着柳杉种植面积的不断扩大,其病害问题也日益凸显.Recently,the needles of Cryptomeria japonica in parks at Fuzhou have suffered from red blight seriously,and this situation is even getting worse.Four diseased needle samples of C.japonica were collected from different parks around.Four Pestalotiopsis strains were obtained after isolation and purification.Based on morphological characters in couple with phylogenetic analyses of sequences of ITS,β-tubulin and tef1,all the strains were identified as Pestalotiopsis hispanica.The results of Koch′s postulates for the represent isolate LS-1 on the needles of healthy C.japonica confirmed P.hispanica as the pathogen of the disease.This is the first report of P.hispanica on C.japonica,even in China.
