红松上的散斑壳

根据子囊果在寄主组织中的位置、生态学特性和松针上线纹有无等特点,将中国东北红松(Pinns koraiensis Sieb et Zucc.)上的散斑壳(Lophodermium Chev.)鉴定为5个种,其中2个新种:寄生散斑壳(Lophodermium parasiticum B. Z.He et Yang),大散斑壳(L.maximumB.Z.He et Yang);3个为我国新记录种:光亮散斑壳(L.nitens Darker)、偃松散斑壳(L.pini-pumilae Sawada)和乔松散斑壳(L.pini-excelsae Abmad)。引起红松落针病的病原菌主要是大散斑壳,其次是寄生散斑壳。

LOPHODERMIUM ON KOREAN-PINE

In this paper, two new species of Lophodermium on Pinus koraiensis are discribed and three known species of Lophoderniium on Piuns korainensis are recorded. These axe L. maximum B. Z. He et Yang sp. nov., L. Parasiticum B.Z. He et Yang sp. nov., L. nitens Darker, L. pini-pumilae Sawada, L. poini-excelsae Abmad. Two new species, i.e.L, maximum and L. parasiticum collected from Liaoning and Heilongjiang Provinces of Northeastern China, and they are pathogenie fungi of needle-cast of Korean-pine in plantation stands. Latin and Chinese diagnoses for new species are given. Holotype of two new species are deposited in the Herbarium of Northeasten Forestry University (HNEFC).
