Seems to fit here best. Noted on shaded entrance to small cave in Orthoquarzite outcrop. Terricolous on skeletal peaty soil, under Lepidothamnus intermedius / Phyllocladus aff. alpinus / Metrosideros umbellata.
Thallus swarding, intertangled, mottled black, black brown with portions pale green-white, not pruinose, not crystalline or areolate, perforations numerous elliptical to rounded, irregular. However, medulla white not black. Cortex K-, C- KC- Pd-.
Of the options in the currently accepted Rexiella for New Zealand this observation fits in R. fuliginosa better than R. sullivanii which has a crystalline cortex, which is yellow, yellow brown, greenish or white with a black medulla - see for example https://inaturalist.nz/observations/19024654
So I am putting this one in Rexiella fuliginosa as a placeholder, on the basis of the available descriptions for New Zealand specimens and consultation with Dr Dan Blanchon.
The white rhizoids in the lower leaf axils (image 5) and the long black tipped changing to gold then white calyptra (image 6) are indicators for this species. The dark line in the centre of the leaf in image 7 is not a costa but a fold in the leaf lamina, another species indicator.
The cells at the leaf base are broader than the other leaf cells and closer to rectangular (image 9). The main lamina cells are like long stretched diamonds that become shorter as you move up the leaf. (11 is lower mid leaf @ 100x and 12 is upper leaf @ 400x)
