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

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

长白山桦树上一种新腐朽病害 总被引：6，自引：0，他引：6
本文报道了我国长白山林区桦树上一种新腐朽病害，其病原菌为斜生纤孔菌Ｉｎｏｎｏｔｕｓｏｂｌｉｑｕｕｓ。该病主要发生在海拔较高的成熟桦树上，主要特征是在树干上形成黑色肿瘤，造成心材白色腐朽，受害树极易风析，后期全株死亡，对病原菌的宏观，显微结构及病害的症状进行了详细描述，并与欧洲的标本进行了比较。 相似文献

An epidemic wood‐decaying fungus, Inonotus rickii, originating from South America, has spread to the Mediterranean area and southern China. We report the first observation of this fungus on Acacia richii in Panzhihua, southern China. It causes serious canker and decay on urban trees in the investigated area. In addition, phylogenetic analysis showed that the fungus from Panzhihua is closely related to isolates from Europe, South America, Mianyang and Hainan of China. Moreover, it was concluded that the isolates of the species previously reported from the USA do not belong to I. rickii. 相似文献

Inonotus rickii was detected for the first time causing cankers and decay in Acer negundo and Celtis australis in Italy. In a boxelder boulevard, declining trees showed sparse foliage, exudations and cracks in the bark; in some cases, chlamydospore masses were present. Five isolates were collected and compared by growth tests in vitro and electrophoretic analyses; three isolates from the same boulevard showed very similar physiological characters. The increasing importance of the pathogen in urban areas is underlined and discussed. 相似文献

Epicoccum purpurascens, a component of the bark micromycota, was evaluated as a potential biocontrol agent for three decay‐causing hymenomycetes frequently found in Buenos Aires city trees, Ganoderma platense, Inonotus rickii and Rigidoporus ulmarius. Treatments consisted of dual cultures of E. purpurascens and xylophagous fungi on box elder (Acer negundo) wood blocks. Two inoculation sequences were tested: (i) the biocontrol agent as the first microorganism inoculated followed by the pathogen; and (ii) the xylophagous fungus as the first microorganism inoculated followed by the biocontrol agent. After 3 months of incubation, percentage dry weight loss was calculated. When E. purpurascens was allowed to colonize wood blocks before the introduction of the xylophagous fungus, dry weight loss was significantly reduced in all instances. However, as a secondary colonizer, E. purpurascens mildly reduced the weight loss caused by G. platense, had no effect on degradation by I. rickii and increased wood weight loss by R. ulmarius. 相似文献

对采自于黑龙江省大兴安岭塔河县和呼中自然保护区的桦褐孔菌子实体及其引起腐朽的木材标本经室内分离、纯化、鉴定,并与白桦健康木相应部位作对照,以揭示该腐朽木上的真菌种类组成。结果表明,从桦褐孔菌腐朽木上共分离出真菌32属,优势菌为青霉属、桦褐孔菌及散蠹菌属;相对于健康桦树木上真菌多13属,其中独有种类23属,两者共有真菌9属,健康桦树木上独有种类10属,说明木材腐朽菌桦褐孔菌可引起树干真菌群落结构显著变化。腐朽木树皮上的真菌种类最多,达到27属。在白桦腐朽木上各个区域内都分离到了桦褐孔菌,但在健康的白桦树各个部位都没有发现。 相似文献

A new lanostane-type triterpene with a cyclopentanol partial structure in the side chain was isolated from the sclerotium of the wood rotting fungusInonotus obliquus along with four known compounds: lanosterol, inotodiol, trametenolic acid, and 3-hydroxy-8,24-dienlanosta-21,23-lactone. The new compound was determined to be 21,24-cyclopentalanosta-3,21,25-triol-8-ene by spectroscopic analyses.An outline of this study was presented at the 50th Annual Meeting of the Japan Wood Research Society, Kyoto 相似文献

采用高脂高胆固醇诱导SD大鼠高脂血症实验模型,分析桦褐孔菌醇提物（IOE）对大鼠体重、脏器及饲喂IOE后大鼠血脂水平和动脉硬化指数。结果表明：IOE可以显著降低高脂血症大鼠血清中甘油三酯、总胆固醇的含量;IOE可以显著提高高脂血症大鼠血清中的高密度脂蛋白胆固醇的水平,降低低密度脂蛋白胆固醇的水平;IOE可以提高高脂血症大鼠的ApoA水平,降低ApoB水平;饲喂IOE后,可明显改善大鼠血脂代谢,对阻止动脉硬化的形成和恶化具有重要作用。 相似文献
