This paper describes Sporolithon franciscanum, a new rhodolith-forming species of non-geniculate coralline algae found at depths between 47–52 m near the São Francisco river mouth, the second largest and the most extensive drainage basin in Brazil, and also at the Abrolhos Bank, in the world´s largest rhodolith beds. DNA sequences from plastidial psbA and rbcL markers indicate that the species is unique compared to all other Sporolithon species that have thus far been sequenced. Since morpho-anatomical features of the new species are shared with some other Sporolithon species, its identification was only confirmed by DNA sequences.

Sporolithon franciscanum sp。十一月 （Sporolithales，Rhodophyta），一种来自巴西东北部的新的形成Rhodolith的物种

本文介绍了Sporolithon franciscanum，这是一种新的形成非菱形珊瑚藻的类红藻形成物种，在圣弗朗西斯科河口附近，巴西第二大和最广泛的流域以及阿伯罗洛斯附近发现，深度在47-52 m之间银行，位于世界上最大的菱锰矿床中。来自质体psb A和rbc L标记的DNA序列表明，与迄今已测序的所有其他Sporolithon物种相比，该物种是独特的。由于新物种的形态解剖特征与其他一些Sporolithon物种共有，因此只能通过DNA序列确认其识别。
