Flora says: On soil or among bryophytes in drainage cracks in rock, often associated with Coccocarpia palmicola... terricolous habit (acid soils); bullate to columnar, brown to reddish brown, dull to glossy, simple to branched squamules, often swollen at apices and with punctiform pseudocyphellae developing into pores; marginate, epruinose, black apothecia developing at tips of squamules.
You can just see the little black apothecia forming and Coccocarpia palmicola at top right of the picture.

Cladonia, growing on stony debris on roadside bank in forest
On rock. Stunning colours!
First time seeing this but one of my new favourites. Local corticolous lichen on pohutukawa.
Local amongst Camylopus under kānuka. Sorediate, K-.
Local on tree stumps. K+ yellow, PD+ yellow - orange. With C. glebosa.
Corticolous on raukawa in frost flat (or close too). Upper surface with pseudocyphellae, K+ Yellow - Red, powdery sorediate mostly marginal, with apothecia.
Corticolous in coastal forest.
Frosted squamules.
Brown when dry.
Spores without peristomes, halonate?, ellipsoid, 12.5 x 11.25 microns.
Large black auriculate apothecia. Spores nonhalonate, colourless, 13 x 6 microns. K-, hypothecium black, exciple dark.
Local saxicolous lichen on basalt boulders. Thallus to 3cm, effuse soredia, heavily fertile.
Corticolous on kauri, white underside, soredia mostly marginal. Upper surface scrobiculate - falveolate. Pseudocyhellae rare. Conidia 6.25 - 8.75 microns long.
On soil on the ground in the middle of a gravel track near the river.
Brownish organism on the stone.
colour change with chemical in bird dropping
Thought this was an unusual Stereocaulon but doesn't seem to key to any.
Saxicolous.
Fertile so am wondering about U. ciliata, as opposed to Usnea acromelana, which appeared to be growing together with this one https://inaturalist.nz/observations/100839924
