Original publication and holotype designation: West, J.A., Hansen, G.I., Hanyuda, T. & Zuccarello, G.C. (2016). Flora of drift plastics: a new red algal genus, Tsunamia transpacifica (Stylonematophyceae) from Japanese tsunami debris in the northeast Pacific Ocean. 31(4): 289-301, 5 figs.
Taxonomic status: currently recognized as a distinct genus.
Familial pacement of the genus unresolved (Hwan Su Yoon, pers. comm.). - (8 Feb 2017) - M.D. Guiry
Description: In culture, vegetative cells are directly released as single non-motile spores (9-12 µm diam.) attaching to a glass substrate and germinating to form radiating, branched uniseriate filaments that become dense pulvinate crusts up to 1mm wide that are often confluent. Horizontally radiating filaments are formed by apical cells undergoing transverse divisions, followed by longitudinal and oblique divisions of intercalary cells to form numerous horizontal and erect branched filaments. No pit connections form between cells. Each cell has one spherical central nucleus about 3 µm diameter, suspended on thin cytoplasmic strands radiating outward across the central vacuole and a single, peripheral, purple to pink, muchlobed plastid without a pyrenoid.
Origin of description: this description is from the original publication; it may have been modified slightly.
Comments: Identity was also established on the basis of SSU, rbcL, and psbA sequences.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.
Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
