Corticolous on pohutukawa (Metrosideros excelsa). Photobiont green. Medulla yellow. Upper surface green when moist, grey when dry. Thallus broadly lobed, upper surface without pseudocyphellae, phyllidia, isidia (well mostly), and maculae; soredia yellow, mostly labriform, sometimes appearing pseudoisidate If so then 'pseudoisidia' minute); underside dark brown, copiously covered in small fleck-like yellow pseudocyphellae. Apothecia not seen. Specimen on which this image is based lodged in F.
Corticolous on ti kouka (Cordyline australis) in raupo reedland. Common. Growing admixed with Podostictina pickeringii. Photobiont green. Thallus very dark greyish-green suffused with red when dry. Medulla yellow. Upper surface without pseudocyphellae, phyllidia, or maculae. Thallus deeply divided, somewhat lacerate, margins (and central portion of thallus) coarsely isidiate; isidia minute, much branched to coralloid, often eroding into yellow soredia with age. Thallus underside brown - suffused red when dry, pseudocyphellae yellow, minute, copious. Apothecia scarce, marginal, pedicellate to subpedicellate.

Locally common. Corticolous on Myrsine australis. Photobiont green, medulla white; thallus much divided, upper surface without soredia, pseudocyphellae, maculae or phyllidia; lobes linear-elongate, tangled, canaliculate, punctate impressed, thallus margins densely covered in coralloid isidia (often tangled); undersides white, smooth, somewhat bullate, glabrous, pseudocyphellae minute, fleck-like scarcely evident on thallus surface. Apothecia not seen. Associated with Podostictina pickeringii, Megalospora sp., and Pannaria elixii. Images from PdL 12739 lodged in UNITEC with Duplicates in AK, F. Images show the same specimen dry and rehydrated, and also the upper and lower thallus surfaces.
Very uncommon. At or close to northern limit for species. Corticolous on rawiri (Kunzea linearis) growing admixed with Podostictina pickeringii, Crocodia poculifera and Pseudocyphellaria aff. crocata. Photobiont green. Medulla white. Thallus without isidia, phyllidia, soredia, margins mostly entire, wavy to smooth (very rarely finely lobulate). Apothecia not seen, Upper surface pseudocyphellate, undersides prominently pseudocyphellate. Image from PdL 12726 Specimen lodged in UNITEC with Duplicate in F.
Locally common. Corticolous on rawiri (Kunzea linearis). Growing in sheets encircling trunk. Photobiont green. Thallus very dark greyish-green suffused with red when dry. Medulla yellow. Upper surface without pseudocyphellae, phyllidia, or maculae. Thallus deeply divided, somewhat lacerate, margins (and central portion of thallus) coarsely isidiate; isidia minute, much branched to coralloid, often eroding into yellow soredia with age. Thallus underside brown - suffused red when dry, pseudocyphellae yellow, minute, copious. Apothecia scarce, few seen subpedicellate to pedicellate. I apologise for crap image - big specimen! Bad camera. Image (taken when dry) based on PdL 12724, specimen lodged in UNITEC with Duplicate in F.
Uncommon. Corticolous on rawiri (Kunzea linearis) trees on exposed cliff crest overlooking forest basin. Photobiont cyanobacterial. Thallus dark red-black when dry, dark blue-black when moist. Upper surface reticulate impressed, densely covered in pustular soredia, these forming a thick sorediate crust across much of the thallus. Isidia, phyllidia and apothecia absent. Thallus underside densely invested in chocolate brown to black tomentum, centrally devoid of pseudocyphellae; pseudocyphellae sparse, concentrated at thallus apices where conspicuous, large and irregular in shape. Image from rehydrated specimen PdL 12723 lodged in UNITEC with duplicate in F.
Uncommon. Corticolous on rawiri (Kunzea linearis). Photobiont green. Thallus reeking of fish when moist. Thallus wihout isidia, soredia or phyllidia, much more deeply divided that I am used to for this species; lobes 5-10(-15) mm wide (also quite narrow for this species) branching pseudo-dichotomous. Lobe margins smooth. Thallus underside pale, darkening centrally, tomentose, tomentum grey-brown to brown. Cyphellae on undersides only, large (2.5-3.0 mm diameter), crateriform. Apothecia prolific, red-brown. In some respects approaches S. livida but the lobes are in the upper range for that species as it is defined by Galloway (2007), and the cyphellae are too large. Images show rehydrated specimen (one with flash to show apothecia better). Specimen PdL 12721, Lodged in UNITEC. Duplicate: F
