在9个偏远、高海拔、超营养和少营养、奥林匹克湖泊和喀斯特山脉湖泊的柱状沉积物中发现了几种蛇毒的种群。其中三个种，P.lacustre，P.alpinum和P.nivale，在这里被描述为新种。用光学和扫描电子显微镜记录了这些物种的二氧化硅小锥的形态。我们讨论了与以前描述的Psammothdium种的异同。
Populations of several Psammothidium species were found in core sediments from nine remote, high elevation, ultraoligotrophic and oligotrophic, Olympic and Cascade Mountain lakes. Three of these species, P. lacustre, P. alpinum , and P. nivale , are described here as new. The morphology of the silica frustules of these species was documented using light and scanning electron microscopy. We discuss the similarities and differences with previously described Psammothidium species.
