The sporophyte of Hymenodon tenellus is newly described. Comparison of types and further specimens allows to clarify the identity in New Caledonia of Bryum daenikeri and Macromitrium serpens and assign them respectively to B. pancheri and M. tongense. Four new species of liverworts: Andrewsianthus chimbuensis, Lejeunea stenodentata, Plagiochila integrilobula and Radula lingulata and new localities of Mitthyridium flavum and Trichosteleum stigmosum are reported.
