中国色球藻科一个新纪录属

A new record genus of Chroococcaceae from China

为了解贵州省树皮藻类物种多样性,在贵州省遵义市采集的样品分析中发现了色球藻科蓝叠球藻属(Cyanokybus)的分布,该属为单种属,仅委内瑞拉蓝叠球藻(Cyanoky busvenezuela)1个种.依据采集的标本对该属种形态特征进行了补充描述;对该属种的生境特征、地理分布进行了初步的讨论.研究结果对蓝叠球藻属(Cyanokybus)区系分布、起源演化、生态特征等后续研究具有较大的参考价值.

In order to understand the species diversity of corticolous algae in Guizhou Province,the distribution of Cyanokybus venezuela,single species in the monotypic genus,was found in the analysis of samples collected in Zunyi City,Guizhou Province.The morphological characteristics of the genus and species were supplemented according to the collected specimens.The habitat characteristics and geographical distribution of Cyanokybus were discussed preliminarily.The results have great reference value for the follow-up research on the flora distribution,origin and evolution,and ecological characteristics of Cyanokybus.
