从10个以前没有报道过的栖息地收集和研究了淡水红鱼Boldia，发现了两个已建立的物种中没有任何一个的标本。Boldia angustataDeason和Nichols被简化为与前面描述的B. Boldia erythrosiphonHerndon emend霍华德和帕克是一个多形的，比以前记录的更广泛的分布。它是多年生植物，在直立囊状叶和匍匐花丝之间交替，并且两个阶段通过假薄壁组织或丝状结构的基部固着物连接。没有观察到有性生殖;然而，无性生殖是由成熟的叶状体释放的单孢子引起的，然后萌发产生基部结构，并通过直立单列花丝的起始最终形成新的叶状体。绝对增长的要求没有确定，但是，栖息地的相似性，特别是丰富的其他红藻属和锰的优势，在蜗牛和岩石基板ofBoldia，建议流温度，化学，基板和光周期的相互作用，限制了分布ofBoldia erythrosiphon。
Collection and study of the freshwater red alga,Boldia, from 10 previously unreported habitats disclosed specimens not assignable to either of the two established species.Boldia angustataDeason and Nichols is reduced to synonomy with the earlier describedB. erythrosiphonHerndon because of significant overlap between the specific characteristics.Boldia erythrosiphonHerndon emend Howard and Parker is a pleomorphic alga with a more widespread distribution than previously recorded. It is perennial, alternating between an erect saccate frond and prostrate filaments, and both phases are linked by a basal holdfast of pseudoparenchymatous or filamentous construction. Sexual reproduction was not observed; however, asexual reproduction resulted from monospores released by mature fronds, which then germinated to produce basal structures, and through the initiation of erect uniseriate filaments eventually formed new fronds. Absolute growth requirements were not determined; however, similarities in habitats, specifically the abundance of other red algal genera and a predominance of manganese in both snail and rock substrates ofBoldia, suggest an interaction of stream temperature, chemistry, substrate, and photoperiod as limiting the distribution ofBoldia erythrosiphon.
