摘　　要：于1983—1986年先后在福建沿岸采集爬管藻标本,进行分类研究。根据有限枝节片数目、囊果的着生位置以及围轴细胞数目等形态特征,发现其中两种标本与已知种的特征不同:一种是囊果位置不定,着生在有限枝基部第4(3)节片以上至顶端节片;另一种是有限枝节片数目较少,由5—12—(14)个节片组成,囊果基生。故定为两个新种,即福建爬管藻Herposiphonia fujianensis sp. nov.和基生爬管藻H.basilaris sp.nov.。模式标本保存于福建师范大学生物系植物标本室。In the paper, two new species of Herposiphonia, namely, Herposiphonia fujianensis sp. nov. and H. basilaris sp. nov. collected in 1983-1986 from the coast of Fujian are reported. The establishments of them are based on the number of segments in determinate branches and the position of cystocarps. The Holotype materials are deposited in the Herbarium of Department of Biology, Fujian Teachers University.1. Herposiphonia fujianensis sp. nov.(Fig. 1; P1. I: 1)Epiphytic algae, with indeterminate prostrate branches 60-90μm in diam., 9(8) pericen-tral cells, mostly with no bare nodes; determinate branches 45-70 μm in diam., composed of 20-37 segments, with 8(9) pericentral cells; chromatophores not zonate; trichoblasts usually lacking; tetrasporangia in straight of 8-16 in the determinate branches; procarps arising on the 4(3) segment from the base to the apex of the determinate branches; cystocarps in similar positions, ovate; spermatangial stichidia not observed.Holotype: F. T. U. 83-39((?),(?)) growing on the other algae in the lower littoral zones, Gul angyu, Xiamen, Fujian Province, on Dec. 9, 1983.The new species is characterized by the varying position of the cystocarps which arise from the base to the apex of the determinate branches. It differs from other species of Herposiphonia reported.2. Herposiphonia basilaris sp. nov. (Fig. 2; P1. Ⅰ: 2; PL Ⅱ)Epiphyic algae, with indeterminate branches 70-110-(130) μm in diam., 8 or, 9 pericentral cells, with no bare nodes; determinate branches 40-65-(75) μm in diam. composed of 5-12-(14) segments, with 8(9) pericentral cells; trichoblasts 2-4, terminal, with 2-3 dichotomies, mostly deciduous; tetrasporangia in straight of 2-5 in the middle or lower part; cystocarps ovate to urceolate, arising on the 2nd or 3rd segment from the bases of the determinate branches; spermatangial stichidia 1 or 2, lanceolate, in the 2nd to 4th segment from the base of the determinate branches.Holotype: F. T. U. 84-77((?),(?),(?)) growing on the other algae in the lower littoral zones,
