Undescribed species common on ti kouka (Cordyline australis) and in the process of being formally described by Andrew Marshall and André Aptroot.
Very common on ti kouka in the Auckland Region (and probably elsewhere).
People will have to believe me as I have not looked at spores but the identification has been confirmed by Andrew Marshall.

When first noted on this island (12 February 2023 - see https://inaturalist.nz/observations/150552121) I had considered it uncommon. However on the day this observation was made (18 April 2023) the island had been subjected to rain showers for several days - all exposed limestone examined was covered in masses of this lichen.
Intriguingly it was not seen in any abundance on the adjacent shoreline of Te Whanga on the same substrate. I speculate the difference is that Motuhinahina has fewer mammalian predators, and as such supports a thriving sea bird population. I wonder if the guano they deposit encourages this lichen to flourish?
