摘要

本文报道了一种来自日本的新红藻，日本红藻Dasya japonovillosa。这个新物种和D.enomotoi都有细长的轴，上面密密麻麻地覆盖着许多柔软的单同源细丝，可能被日本以前的研究人员误认为D.villosa。绒毛Dasya与D.japonovillosa和D.enomotoi的不同之处在于横切面上有不同的五个中央周围细胞和栅栏状四孢子囊覆盖细胞。该新物种与几种类似物种的区别在于以下方面：细长的轴（至65厘米）、分区轴和多同源分支、除顶端附近外横截面上不明显的中央周围细胞，以及扩大的内部皮层细胞，径向排列的许多柔软的单同源细丝，三个细胞的车皮原细胞分支，每个可育段有四个四孢子囊，以及一个（很少有两个）四孢子囊覆盖细胞，不纵向伸长，很少横向分裂。

A new red alga from Japan, Dasya japonovillosa sp. nov. (Delesseriaceae, Ceramiales)

A new red alga from Japan, Dasya japonovillosa, is described. This new species and D. enomotoi, both of which have elongated axes densely covered with numerous soft monosiphonous filaments, may have been misidentified as D. villosa by previous investigators in Japan. Dasya villosa differs from D. japonovillosa and D. enomotoi in the distinct five pericentral cells in transverse sections and palisade‐like tetrasporangial cover cells. The new species is distinguished from several similar species by the combination of the following: an elongated axis (to 65 cm), subdichotomously divided axes and polysiphonous branches, indistinct pericentral cells in transverse sections except near the apices, and the presence of enlarged, inner cortical cells, radially arranged numerous soft monosiphonous filaments, three‐celled carpogonial branches, four tetrasporangia in each fertile segment of the stichidia, and one (rarely two) tetrasporangial cover cell that is not elongated longitudinally and rarely divided transversely.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
