Abstract
Notice of the presence of Caloplaca johnwhinrayi S.Y.Kondr. & Kärnefelt (Teloschistaceae) previously considered an Australian endemic is given. The species is known from a single collection from limestone rocks on Motuhinahina Island within Te Whanga Lagoon, Rēkohu / Wharekauri / Chatham Island (the largest of the Chatham Islands group), Aotearoa / New Zealand. Brief notes on the species recognition, ecology and conservation are given with the recommendation that it should be looked for in similar habitats elsewhere in Aotearoa / New Zealand.
