对来自黑龙江的木霉属真菌进行系统分类研究,报道了该属3个中国新记录种:平展橙红木霉Trichoderma auranteffusum,塔梗木霉T.pyramidale和革菌生木霉T.thelephoricola,对其宏观和微观特征提供了详细描述及图示,系统发育分析为上述种的分类地位提供了佐证。
Collections of Trichoderma on decaying wood from Heilongjiang Province were examined. Three species, T. auranteffusum, T. pyramidale and T. thelephoricola, are new to China. Descriptions and illustrations of these fungi are provided. Their taxonomic positions are confirmed by phylogenetic analyses of the combined sequences of RNA polymerase II subunit b and translation elongation factor 1-alpha genes.
