rbcL序列的系统发育分析表明，目前构成的Calliarthron是并系的。产于西北太平洋的Calliarthronyessoense和C latissimum同属Alatocladia。C. yessoense和C. latissimum，Calliarthron是一个单系，只在东北太平洋发现，包括两个种，C. cheilosporioides和C tuberculosum，这是不同的形态，地理和分子序列。C. regenerans和C. setchelliae证实它们是C.结核病选择型为C. cheilosporioides，C. regenerans和C.刺毛形态计量学分析表明，三个测量特征可靠地区分C。cheilosporioides从C tuberculosum。Alatocladia是单系的，只在西北太平洋发现，包括两个种，A。modesta和A. yessoensis，它们在形态、地理和分子序列上是不同的。模式种Alatocladia，Bossiella，Calliarthron和Chiharaea的rbcL序列数据确信区分这些属具有强大的自举支持。
Phylogenetic analyses of rbcL sequences demonstrate that Calliarthron as currently constituted is paraphyletic. Calliarthron yessoense and C latissimum from the northwest Pacific belong in Alatocladia and are conspecific. After the transfer of C. yessoense and C. latissimum, Calliarthron is monophyletic, known only from the northeast Pacific and comprises two species, C. cheilosporioides and C tuberculosum, which are distinct morphologically, biogeographically and by molecular sequence. Sequence data for the types of C. regenerans and C. setchelliae confirm that they are heterotypic synonyms of C. tuberculosum. Lectotypes are designated for C. cheilosporioides, C. regenerans and C. setchelliae. A morphometric analysis shows that three measured characters reliably distinguish C. cheilosporioides from C tuberculosum. Alatocladia is monophyletic, known only from the northwest Pacific and comprises two species, A. modesta and A. yessoensis, which are distinct morphologically, biogeographically and by molecular sequence. rbcL sequence data of the type species of Alatocladia, Bossiella, Calliarthron and Chiharaea confidently differentiate these genera with strong bootstrap support.
