Muscicolous at base of Melicytus lanceolatus. Uncommon. Cyanobacterial. Thallus arising from prominent stalked, holdfast; lobes narrow to broad, laciniate, dark blue-black above, grey-black when dry, margins crenate, ragged or irregularly incised, densely isidiate, and often lobulate; isidia coralloid-lobulate, often becoming phyllidiate; lower surface dark brown, often paler toward margins; cyphellae prominent, white, somewhat sparse; Apothecia not seen.
Corticolous. Cyanobacterial. Thallus reeking of rotting fish when moist; monophyllous, lobulate in this variant, lobes rounded, lobules rounded with prominent ciliate margins; upper surface wrinkled, chartaceous, orange-brown to dirty brown, with blackened minute, terete, coralloid isidia; undersides pale brown to whitish, cyphellate, cyphellae large. Unnamed species currently included in the broad circumscription advocated for Sticta fuliginosa (a northern hemisphere species) in New Zealand. Voucher in UNITEC
Corticolous. Thallus upper surface bright green when moist, grey-green when dry, without pseudocyphellae, branching dichotomous to trichotomous, lobes linear, margins entire, sinuous, without soredia, isidia or phyllidia; undersides black, pseudocyphellae numerous, white. Apothecia sparse, marginal red-brown, margins fimbriate. Abundant at this site.
Abundant. Corticolous on makamaka (Ackama rosifolia), towai (Weinmannia silvicola) and toro (Myrsine salicina). Common. Thallus cyanobacterial, without isidia, soredia, or phyllidia, dark blue-green to steel blue, broadly lobed, reticulate-faveolate, punctate impressed above; undersides bullate, uniformly covered in fine brown tomentum; pseudocyphellae minute, sparse, off-white; medulla white; apothecia numerous, black.
Corticolous on makamaka (Ackama rosifolia. Common - Photosymbiodeme - green symbiont, thallus upper surface when moist, pseudocyphellate, without isidia, soredia or phyllidia, lobes entire, broadly rounded; lower surface white at margins, otherwise brown-black, tomentose, pseudocyphellae numerous, conspicuous, with a prominent rim (so appearing like cyphellae); medulla white; apothecia occasional, red-brown, submarginal; cyanobacterial component (formerly P. knightii D.J.Galloway) similar but upper surface blue-black when moist, faintly maculate.
Corticolous on matipo (Myrsine chathamica) in sinkhole on trachyte peak, associated with Psoroma sp., and Pseudocyphellaria physicospora. Uncommon. Thallus large (over 200 mm diameter), dark chocolate brown when fresh, strongly punctate impressed; lobes broad, rounded, overlapping, apices finely tomentose otherwise glabrous; sorediate, soralia confined to ridges, yellow; undersides pale to buff-coloured, tomentose, pseudocyphellae copious, minute, fleck-like, yellow. Medulla white, Apothecia not seen. A distinct unnamed species currently included within the New Zealand concept of P. crocata
Corticolous on mountain beech (Fuscospora cliffortioides). Abundant. Thallus pale green when moist, grey-green when dry, much divided, laciniae lacerate, margins isidiate, especially toward laciniae bases and sinuses; undersides densely invested in dark chocolate brown tomentum except for margins where almost glabrous, so whitish in colour; pseudocyphellae numerous, white, immersed in tomentum, fleck-like; medulla white. Apothecia not seen.
Epiphytic on live crabapple.
Corticolous on mountain beech (Fuscospora cliffortioides). Thallus upper surface green when moist, grey when dry, distinctly tomentose, often with small portions of minute, granular, coralloid, tomentose isidia; undersides of thallus white, densely tomentose; pseudocyphellae on undersides only, minute, fleck-like, yellow and sparse; medulla white; apothecia not seen
Corticolous on matai (Prumnopitys taxifolia) in riparian forest. Thallus cyanobacterial, deeply divided (lacerate) but with laciniae overlapping at apices, punctate impressed above, dark blue-grey when moist, grey when dry; soredia yellow, granular, sparse mostly on ridges of central portion of thallus, also margins of the thallus lobes near sinuses, often minute and then pustular; undersides chocolate-brown, pseudocyphellae minute, fleck-like, copious; medulla white; apothecia not seen. Unnamed species, one of a group of unnamed taxa previously treated as 'shade forms' of P. crocata
Corticolous on matai (Prumnopitys taxifolia) in riparian forest. Thallus cyanobacterial, deeply divided (lacerate), punctate impressed above, dark blue-grey when moist, grey when dry, maculate; soredia yellow, granular, mostly in central portion of thallus and on margins of the thallus lobes near sinuses; undersides chocolate-brown, pseudocyphellae minute, fleck-like, copious; medulla white' apothecia not seen. Unnamed species, often incorrectly stated to be a 'shade form' of P. crocata.
Saxicolous on fractured greywacke rock above roadside. Thallus cyanobacterial, chocolate brown when fresh, soredia yellow, copious, farinose-granular, often forming thick crust across central portions of thallus and minute pustular 'beads' on young portions of thallus; undersides dark chocolate brown, pseudocyphellae yellow, copious, conspicuous; medulla white; apothecia not seen. A widespread unnamed species currently included in P. crocata
