DB7987E7EB2FFF82FEC5FAC2D9E9FD0A.taxon	diagnosis	DIAGNOSIS. — Thalli prostrate, 1 - 2 cm in diameter, attached to substrate by scattered clumps of rhizoids on the lower blade surface, margins unattached with a ruffled / undulating appearance (Fig. 2). Thallus distromatic, cells rectangular; 45 - 55 µm thick at edge; becoming thicker in central regions (90 - 165 µm) with adaxial cell layer becoming deeper (80 - 100 µm) than the abaxial cell layer (40 - 60 µm). Rhizoids develop from both of the cell layers and join to form rhizoidal clumps 50 - 140 µm in diameter extending from the lower thallus surface to 180 - 220 µm in length (Figs 5 A, B). HABITAT. — Subtidal on rock and non-geniculate coralline algae, growing in patches on boulders, rocky reef and also found on stable cobbles and stones.	en	Heesch, Svenja, Sutherland, Judy E., Ringham, Sandi, Nelson, Wendy A.

DB7987E7EB2FFF82FEC5FAC2D9E9FD0A.taxon	etymology	ETYMOLOGY. — piri (to stick, adhere, cling, keep close), toka (rock); in reference to the habit of this species, clinging tightly to the surface of rocks and withstanding the constant flow of current.

DB7987E7EB2FFF82FEC5FAC2D9E9FD0A.taxon	discussion	COMMENTS Underwater images from the islands show Ulva piritoka Ngāti Kuri, Heesch & W. A. Nelson, sp. nov. to occur commonly on a range of rocky substrata, sometimes forming extensive patches. It was seen to grow on bare rock as well as over nongeniculate corallines and also interspersed with sponge and other encrusting benthic species.	en	Heesch, Svenja, Sutherland, Judy E., Ringham, Sandi, Nelson, Wendy A.
