| 摘要:本文报道秦岭地区尾孢菌属及其近似属56种,其中有一个新种:秦岭假尾孢(Pseudocercospora qinlingensis Guo, sp. nov.),寄生在苦木科(Simaroubaceae)臭椿属(Ailanthus sp.)上,两个新组合:草霉色链隔孢[Phaeoramularia vexans (C. Massalongo) Guo,comb. nov.].寄生在蔷薇科(Rosaceae)草霉属(Fragaria sp.)上;篙假尾孢[Pseudocercospora dracunculi (Sarwar) Guo, comb. nov.],寄生在菊科(Compositae)牛尾蒿(Artemisia subdigitataMattf.)上和两个中国新记录种:商陆尾孢(Cercospora pircuniae Speg.),寄生在商陆科(Phytolaccaceae)商陆(Phytolacca acinosa Roxb.)上;荚蒾生尾孢(Cercospora viburnicola Ray).寄生在醉鱼草叶荚蒾(Viburnum buddleifolium C. H. Wight)上.新种(Pseudocercospora qinlingensis Guo, sp. nov.)子实体主要生于叶面,子座沿叶斑边缘发生,暗褐色至近黑色,直径40.0-75.0 (-100.0)μm,分生孢子梗紧密簇生,青黄褐色,不分枝,不呈曲膝状,无隔膜,6.5-26.0 × 3.9-6.0μm,分生孢子圆柱形,青黄褐色至中度褐色,非常弯曲,基部平截,具紧密排列地4至多个隔膜,在隔膜处缴缩,32.0-120.0 (-150.0) ×4.0-6.5 (-7.6)μm.新种与寄生在臭椿属(Ailanthus spp.)植物上的臭椿尾孢(Cercospora ailanthi P. Henn.)和臭椿生假尾孢[Pseudocercospora ailanthicola(Patwardhan) Dcighton]不同:臭椿尾孢无子座.分生孢子梗不成簇,分枝,长(50.0-200.0μm),分生孢子倒棍棒一圆柱形,色泽浅(浅青黄褐色),隔膜少(5-7隔),不缢缩,短(15.0-60.0μm);臭椿生假尾孢子实体叶背生,分生孢子梗窄((3.0-4.Spm),分生孢子倒棍棒形,隔膜少((5-8隔),不绣缩,短而窄(20.0-63.0 ×3.0-5.0μm). |

| Fifty-six species of Cercospora and allied genera collccted from the Qinling Mountains are reportcd in the present paper. One new species: Pseudocercospora qinlingensis Guo, sp. nov. on Ailanthus sp. (Simaroubaceae), two new combinations: Phaeoramularia vexans (C. Massalongo) Guo, comb. nov. on Fragaria sp. (Rosaccae), Pseudocercospora dracunculi (Sarwar) Guo, comb. nov. on Artemkia subdigitafa Mattf. (Compositae) and two ncw records for China: Cercospora pircuniae Speg. on Phytolacca acinosa Roxb. (Phytolaccaccac), Cercospora viburnicola Ray on Viburnum buddleifolium C. H. Wight (Caprifoliaccae) are included. Latin diagnosis of the new spccics and descriptions of the new combinations are provided. Specimens examined are deposited in HMAS. |
