Chiloscyphus anisolobus J. J. Engel & Glenny, a new member of the Lophocoleaceae, is described and illustrated from New Zealand. Chiloscyphus anisolobus J. J. Engel & Glenny shares the possession of a dorsal leaf free strip and strongly anisophyllous habit with the Australian C. excisifolius, but is distinct from that species in the accessory armature of its leaves, wherein the ventral margin often has a dentiform to lobuliform process in the distal sector, the leaves thus appearing trifid; the shorter leaf lobes terminating in a single cell or a uniseriate row of 2–3(–4) cells; and the shorter underleaf lobes terminating in a single cell or a uniseriate row of 2–3(–4) cells.
