A new sorediate lichen, Menegazzia hypernota Bjerke, is described from New Zealand. This new species is characterised by convex, crescent‐shaped to fabi‐form soralia that are occasionally associated with perforations; apothecia with 2‐spored asci; the small perforations; the numerous secondary lobules; the presence of inconspicuous, yellow spots in the internal cavity; and fumarprotocetraric acid as principal medullary constituent. Menegazzia caliginosa, a species associated with M. hypernota, is reported for the first time from the Auckland Islands.
