摘要
对辽东主要地区发生落针病的赤松针叶上采集病害标本,室内进行分类鉴定,确定了在赤松针叶上有5种真菌,均是活体寄生。按照Minte(r1981)分类标准进行了形态学种的分类鉴定,最后确定了5种真菌的分类地位,5个种分别为针叶树散斑壳菌、松散斑壳菌、光亮散斑壳菌、雪松散斑壳、小环绵盘菌。其中有3个种为我国赤松寄主上新记录种。
5 parasitic living fungi were determined on needle leaves of Pinus densfllora endangered with needle cast by collecting samples in eastern Liaoning and indoor classification and identification. Morphological identifications were conducted in accordance with Minter＇ s division criteria （ 1981 ）, such 5 fungi as Lophodermium conigenum,L.pinastri,L.nitens,L .cedrinum and Cyclaneusula minus were classified.
