文章报道了采自四川木格措的十字脆杆藻科(Staurosiraceae)硅藻植物5属13种,包括2个中国新记录属:拟十字脆杆藻属Pseudostaurosiropsis和十字型脆杆藻属Stauroforma,6个中国新记录种:康乃迪克拟十字脆杆藻Pseudostaurosiropsis connecticutensis Morales,窄十字型脆杆藻Stauroforma exiguiformis (Lange-Bertalot)Flower,Jones & Round,圆形假十字脆杆藻Pseudostaurosira cataractarum (Hustedt) Wetzel,Morales & Ector,串连假十字脆杆藻Pseudostaurosira trainorii Morales,拟连结假十字脆杆藻Pseudostaurosira pseudoconstruens(Marciniak) Williams & Round和喜寒窄十字脆杆藻Staurosirella frigida van de Vijver & Morales。文章对每个种类的形态、生境特征以及地理分布进行了详细描述,同时结合新的分类系统,对《中国淡水藻志(第十卷)》中十字脆杆藻科种类进行了整理修订。

TAXONOMY OF STAUROSIRACEAE (BACILLARIOPHYTA) FROM MUGECUO,SICHUAN PROVINCE,CHINA

5 genera 13 taxa of Staurosiraceae (Bacillariophyta) were collected from Mugecuo Scenic Area, Sichuan province, China. Among them, 2 genera of Pseudostaurosiropsis Morales and Stauroforma Flower, Jones & Round were newly recorded in China, and there are 7 newly recorded species of China: Staurosirella frigida Van de Vijver & Morales, S. martyi (Héribaud-Joseph) Morales, Pseudostaurosira cataractarum (Hustedt) Wetzel, Morales & Ector, P. pseudoconstruens (Marciniak) Williams and Round, P. trainorii Morales, Pseudostaurosiropsis connecticutensis Morales and Stauroforma exiguiformis (Lange-Bertalot) Flower Jones & Round. The detailed morphology, habitat characteristics and geographical distribution of each taxon were given. Moreover, according to new classification system, Staurosiraceae species were revised in Algarum Sinicarum Aquae Dulcis (Tomus X).
