Phycodrys denticulatus (Tokida) J.M.Freese & C.E.Lane comb. nov. (Figs 5–7) DESCRIPTION: Thallus parasitic on Phycodrys fimbriata (Kuntze) Kylin. The parasitic thallus is yellow in color, 2 mm in diameter, with several cylindrical irregular branches, branches no longer than 3 mm, emerging from a small hemispherical cushion. The protologue description can be found in Tokida (1934). BASIONYM: Polycoryne denticulata Tokida (1934), Transactions of the Sapporo Natural History Society vol. 13, p. 199, Fig.1.

Tokida, 1934) SEQUENCED SPECIMEN: Collected in the Stefansson Sound Boulder Patch in July 2016 at 70˚19.25’ N, 147˚35.1’ W, Barrow, Alaska, USA, deposited NY03684214, NY03384216 (coll. A.
