An investigation of two of these, Myriogramme crispata and M. denticulata from New Zealand, demonstrates that they comprise a single morphologically variable species, Haraldiophyllum crispatum (J.D. Hooker et Harvey) comb. nov., that is separable from Myriogramme. A morphological and molecular study of the New Zealand species together with the type species of Haraldiophyllum, H. bonnemaisonii, from the British Isles, establishes that the genus is correctly placed in the tribe Myriogrammeae. It differs from Myriogramme in having sympodially developed solitary terminal carposporangia rather than carposporangia borne in chains and sterile-group cells that fuse during carposporophyte development rather than remaining separate. RbcL analyses revealed that a range of forms of H. crispatum from the North, South and Stewart Islands were identical and that H. crispatum was sister to H. bonnemaisonii. No relationship between Haraldiophyllum and Myriogramme was found in the rbcL analyses; however, a sister relationship between the two was moderately supported in maximum parsimony analysis of the Large subunit rDNA (LSU) and was strongly supported in a Bayesian analysis. Our studies indicate that many species with similar morphologies placed in Haraldiophyllum, Myriogramme and Nitophyllum require reinvestigation.} }
