头孢藻属中国新记录种

Newly recorded species of Cephaleuros in China

头孢藻属(Cephaleuros)是一类寄生性藻,在分类学上位于绿藻门石莼纲橘色藻目橘色藻科。国内对头孢藻属的研究多见于它对经济作物和观赏植物的危害,而分类学研究较缺乏。为了全面系统地了解中国头孢藻属的多样性,于2012-2018年先后在多个省份采集头孢藻属标本60余份,并对其进行了形态分类学研究。结果显示,头孢藻属中国新记录种有6种,分别为:寄生头孢藻(Cephaleuros parasiticus Karsten)、德鲁特头孢藻(Cephaleuros drouetii Thompson&Wujek)、肿毛头孢藻(Cephaleuros tumidae-setae Thompson&Wujek)、散生头孢藻(Cephaleuros diffusus Thompson&Wujek)、宽阔头孢藻(Cephaleuros expansa Thompson&Wujek)、亨宁头孢藻(Cephaleuros henningsii Schmidle),对6个种的形态学特征进行了详细描述,并提供了照片资料。

The green algal genus Cephaleuros belongs to class Ulvophyceae,order Trentepohliales,and family Trentepohliaceae.Domestic study on Cephaleuros has primarily focused on its harm to cash crops and ornamental plants,with detailed taxonomic studies remaining scarce.Here,we conducted a comprehensive and systematic study on the diversity of the Cephaleuros genus in China.From 2012 to 2018,more than 60 specimens of Cephaleuros were collected from several provinces in China,and morphological taxonomic analysis was carried out.In total,six newly recorded species were observed,including Cephaleuros parasiticus Karsten,Cephaleuros drouetii Thompson&Wujek,Cephaleuros tumidae-setae Thompson&Wujek,Cephaleuros diffusus Thompson&Wujek,Cephaleuros expansa Thompson&Wujek,and Cephaleuros henningsii Schmidle.Their morphological characteristics were described here in detail and photos of the six newly recorded species were provided.
