Mesophyllum erubescens的名称被应用于有时大量出现的突起红石标本，以及西太平洋、印度洋和西大西洋热带和温带水域的包壳标本。从挑战者考察队在费尔南多诺罗尼亚群岛采集的140年前的正型标本中获得了一个约占红细胞L基因20%的DNA序列。这一序列与现场采集的地表型标本以及沿巴西海岸向南的标本相同。从这些相同的巴西标本和来自墨西哥东海岸的标本中获得的PSB A的序列相同或相差1个碱基对。相反，根据太平洋的形态解剖学特征，被称为erubescens的标本与西大西洋的标本相差2.5-13.1%，表明这些标本代表了许多不同的物种。根据形态解剖特征，所有据说广泛分布于不同海洋或不同生物地理省份的非膝状珊瑚物种的报告都需要通过DNA序列来验证。
The name Mesophyllum erubescens has been applied to protuberant rhodolith specimens which sometimes occur abundantly, as well as to encrusting specimens in tropical and temperate waters in the Western Pacific, Indian and Western Atlantic Oceans. A DNA sequence, representing about 20% of the rbc L gene, was obtained from the 140 year old holotype specimen collected in the Fernando de Noronha Archipelago by the Challenger Expedition. This sequence was identical to field-collected topotype specimens as well as to specimens ranging south along the coast of Brazil. Sequences for psb A from these same Brazilian specimens and specimens from the east coast of Mexico were identical or differed by 1 base pair. In contrast, specimens called M. erubescens based on morpho-anatomical characters in the Pacific Ocean differed from Western Atlantic Ocean specimens by 2.5–13.1%, indicating that these represent numerous distinct species. All reports of non-geniculate coralline species said to be widely distributed across different oceans or in different biogeographic provinces based on morpho-anatomical characters need to be verified by DNA sequences.
