The name Hypopterygium rotulatum (Hedw.) Brid. was formerly applied in New Zealand. Hans Kruijer, though, regarded this as a dubious species and identified specimens formerly named as Hypopterygium rotulatum as Hypopterygium didictyon and as a number of other species. His 2012 publication stated: "Hedwig’s description and illustrations of H. rotulatum [as the basionym, Leskea rotulata] do not differentiate this taxon from other Hypopterygium species, and they have caused considerable confusion (Kruijer, 2002). Specimens from Australia that had been identified as H. rotulatum proved to be either H. didictyon or H. tamarisci. H.N.Dixon’s (Bull. New Zealand Inst. 3(5): 296, 1927) H. rotulatum agrees with H. tamarisci. Reports of H. rotulatum in G.A.M.Scott & I.G.Stone (The Mosses of Southern Australia 396, 1976) are referable to H. didictyon and H. tamarisci.
