通过组织分离及物种鉴定，对信阳杉木内生真菌种类进行了研究．得到丝孢纲（ Hyphomycetes）和腔孢纲（Coelomycetes）真菌4科12属15种．淡色孢科（Moniliaceae）3属5种，暗色孢科（Dematiaceae）2属2种，黑盘孢科（Melanconidaceae）2属3种，球科孢科（Sphaeropsidaceae）5属5种，这些真菌均为半知菌，是杉木内生真菌首次记载．其中，拟茎点霉Phomopsis sp．、球刺盘孢菌Colletotrichum coccodes分布于杉木各样地各器官，为杉木内生真菌广布种．

By tissue isolation and species identification, the species of endophytic fungi from Cunninghamia lan-ceolata were studied in Xinyang area.The results showed that total of 15 fungal species among 12 genera belonging to 4 families and 2 classes, Hyphomycetes and Coelomycetes, were obtained.Five species belonging to 3 genera in Mo-niliaceae, two species belonging to 2 genera in Dematiaceae, two species belonging to 3 genera in Melanconidaceae and five species belonging to 5 genera in Sphaeropsidaceae were reported.All the fungal species described belonged to Deuteromycotina and they were recorded for the first time as endophytic fungi in Cunninghamia lanceolata tissues.It was also found that the Colletotrichum coccodes and Phomopsis sp.distributed in every organ and every sample plot, they were dispersed species of endophytic fungi in Cunninghamia lanceolata plants.
