本文是中国东北地区木腐菌研究结果的一部分,简要论述了中国东北地区杨树上的木材腐朽菌,共报道了生长在杨树或杨树木材及腐木上的担子菌121种。其中多数生长在杨树倒木或朽木上,大多数造成白色腐朽,少数导致褐色腐朽。硬粗毛孔菌Funaliatrogii(Berk.)Bondartsev&Singer和浅黄褐栓菌Trametesochracea(Pers.)Gilb.&Ryvarden等为人工林及行道树上常见种类;中国锐孔菌OxyporussinensisX.L.Zeng和瓦尼木层孔菌PhellinusvaniniiLjub.等种类只发生在杨树原始林或保存完好的天然林分,它们当中有的为稀有种或濒危种类。杨纤孔菌Inonotusrheades(Pers.)Bondartsev&Singer和大孔薄孔菌AntrodialeucaenaY.C.Dai&Niemel 等是杨树上特有种类;杨木层孔菌Phellinustremulae(Bondartsev)Bondartsev&Borisov和树舌灵芝Ganodermalipsiense(Batsch)G.F.Atk等为杨树上的病原菌。 相似文献

本文报道了两种生于杨树上的多孔菌,杨生薄孔菌(AntrodialeucaenaY.C.Dai&Niemel )和西伯利亚毡被孔菌(Spongipellissibirica(Penzina&Ryvarden)Penzina&Kotir.)。根据所采集标本对其进行了详细描述。杨生薄孔菌的主要特征为子实体平伏反转,二系菌丝系统,生殖菌丝具锁状联合,担孢子圆柱形,造成杨树木材褐色腐朽。杨生薄孔菌目前只发现在中国东北,该种与垫状薄孔菌(Antrodiapulvinascens(Pilat)Niemel )和大孔薄孔菌Antrodiamacra(Sommerf.)Niemel 较类似,但垫状薄孔菌的担子果不形成真正的菌盖,其担孢子为椭圆形,菌丝组织中无结晶体存在。大孔薄孔菌也生长在杨树上,但该种只形成平伏的子实体,其孔口和担孢子均比杨生薄孔菌大。西伯利亚毡被孔菌目前只发现在中国东北和俄罗斯的西伯利亚地区,其主要特征为子实体盖状、白色、肉质,单系菌丝系统,生殖菌丝具锁状联合,担孢子椭圆形至近圆形,通常生长在杨树活立木上,造成木材白色腐朽。该种与同属的松软毡被孔菌Spongipellisspumea(Sower by:Fr.)Pat.很接近,但后者的孔口为圆形且完整,其担孢子比西伯利亚毡被孔菌的大。 相似文献

Poroid species of wood-inhabiting fungi growing on spruce (Picea koraiensis Nakai or Picea yezoensis (Sieb. & Zucc.) Carriere) in Northeast China were investigated during 1993-2002, and 71 species were recorded from these trees or their wood. Skeletocutis lilacina A. David & Jean Keller and Skeletocutis papyracea A. David are new to China. Fomitopsis pinicola (Sw.:Fr.) P. Karst., Onnia leporina (Fr.) H. Jahn, Perenniporia subacida (Peck) Donk, Phaeolus sckweinitzii (Fr.:Fr.) Pat., Phellinidium sulphurascens (Pilat) Y.C. Dai and Phellinus yamanoi (Imazeki) Parmasto are the pathogens on the two trees. Among the 71 species 18 species (ca. 25% of all species) are considered as rare species, 34 species (48% of all species) are the occasional species, and 19 species (27% of all species) are the common species. 相似文献

To determine whether the brown root rot disease caused by Phellinus noxius is present in the Amami islands, which are situated near Okinawa, we conducted six field surveys from 1999 to 2005. The brown root rot disease was found in 22 tree species in 17 plant families at 25 different sites in all the islands surveyed. Sixteen of these species were newly recorded as host plants of P. noxius. The disease was more common in the low elevation plains and on hills less than 100 m above sea level than in mountainous areas. This is the first report of the brown root rot disease caused by P. noxius in the Amami Islands, Japan, and Ohshima Island is currently the northern‐most distribution point of the disease in the northern hemisphere. 相似文献

Trunk rot, caused by Fomitiporia torreyae, is one of the most economically important sap rot diseases on Cryptomeria japonica, especially on a cutting cultivar ‘Sanbu-sugi’. This disease had been reported only from Chiba and Ibaraki prefectures in Japan; however, a similar trunk rot on Japanese cedars was found recently in Kyoto prefecture. We identified the causal agent of the trunk rot on Japanese cedars in Kyoto prefecture, clarified the genotype of ‘Sanbu-sugi’ (sensu stricto) using microsatellite markers, and then investigated the relatedness of these infected cedars with ‘Sanbu-sugi’. The pathogen was identified as F. torreyae by its DNA sequences and morphological characteristics of the fruiting body. The 25 ramets of ‘Sanbu-sugi’ had only one genotype based on eight microsatellite loci. Infected Japanese cedars in Kyoto were comprised of different genotypes and showed no close relatedness to ‘Sanbu-sugi’. This is the first report of trunk rot caused by F. torreyae on cultivars of Japanese cedar with no relatedness to ‘Sanbu-sugi’ outside of Chiba and Ibaraki prefectures and showed the potential for expansion of this disease to Japanese cedar plantations in other areas. 相似文献

The fungus Phellinus noxius has a broad host range and causes brown root rot in a variety of tree species of various ages, irrespective of their original health. The fungus is widely distributed in tropical countries of Southeast Asia, the Pacific Islands and Australia, Central America and Caribbean, and Africa. Since 1988, when brown root rot was first found on Ishigaki Island, Okinawa Prefecture, the disease has been reported on several islands in Okinawa and Kagoshima Prefectures, and it has been causing serious problems to shade, windbreak, ornamental and landscape trees in the Ryukyu Islands, located in the subtropical region of southern Japan. Here, we report on the current status of P. noxius‐caused brown root rot in the Ryukyu Islands, Japan, including symptoms, occurrence, dispersal, distribution and host tree species of the disease, pathogenicity and/or virulence of the pathogen, and disease management based on our surveys and previously published reports from Japan. Brown root rot has been confirmed in 53 tree species from 32 plant families at different sites on 10 of the 12 islands surveyed. Among the 53 tree species, 34 were first recorded in Japan as host plants of P. noxius. The disease occurs mainly in shade, ornamental and windbreak trees at sightseeing places, parks, roadsides, agricultural land such as sugar cane fields, and around residences or other places associated with human activities. 相似文献
