1）棒杆球腔菌Rhabdosphaera clavigera：Murray & Blackman（1898）研究了从网捕样品中采集的颗石藻，并首次报道了活的棒杆球，由此他们描述了棒杆球腔菌Rhabdosphaera clavigera的属和种。Lohmann（1902）描述了第二个种，R. stylifera，产于地中海，与R.呈阑尾状的棒形。前者有一个由细小元素组成的细茎，而后者有一个更粗、更粗的茎。在最近的分类学著作（Okada & McIntyre，1977; Hallegraeff，1984）中，这两个种被认为是同种的，R. clavigera优先。中间形式已被发现（Borsetti & Cati，1972; Hallegraeff，1984; Norris，1984），但我们认为，茎类型是不同的，足以被分离为变种，使未来的分布研究可能提供有用的信息，他们的个人地理。
TAXONOMIC NOTES 1) Rhabdosphaera clavigera: Murray & Blackman (1898) studied coccolithophores from net haul samples and reported living rhabdospheres for the first time, from which they described the genus and species Rhabdosphaera clavigera. Lohmann (1902) described a second species, R. stylifera, from the Mediterranean, differing from R. clavigera in its appendix shape. The former possesses a thin stem composed of fine elements, whereas the latter has a thicker, coarser stem. In recent taxonomic works (Okada & Mclntyre, 1977; Hallegraeff, 1984) the two species have been regarded as conspecific, with R. clavigera having priority. Intermediate forms have been seen (Borsetti & Cati, 1972; Hallegraeff, 1984; Norris,1984) but we believe that the stem types are distinct enough to be separated as varieties so that future distribution studies may provide useful information on their individual biogeographies.
