Living on dead wood with Xanthoria.
Local. Both saxicolous (see http://naturewatch.org.nz/observations/1827151) and corticolous - and then only seen on keketerehe (Olearia chathamica).
Corticolous on keketerehe (Olearia chathamica). Thallus loosely to tightly attached centrally, margins ± free. Lobes ± rounded and ragged-incised. Margins notched and incised, sinuous, phyllidiate. Upper surface bright-green or glaucous-green when moist, greyish yellow when dry, soredia, maculae, and pseudocyphellae absent. Phyllidia forming a dense crust somewhat obscuring thallus. Medulla yellow. Photobiont green. Lower surface pale yellowish to yellow-white at margins, darker yellow to yellow-brown centrally. Pseudocyphellae yellow, scattered, fleck-like, round to irregular, sunk in tomentum. Apothecia present but immature. Voucher collected for Field Museum (F) DNA study
black crusty lichen on the trunk of an erythrina variegata tree.
Locally common on rock and also on the exposed branches of keketerehe (Olearia chathamica). Only seen on this island on the Northern Summit. This is possibly the southern limit for this species in New Zealand.
Amazing fence of about a bizillion species of lichen. We giggled like Lichen nerds from sheer joy.
I'd seen this species last in Northern California
Fantastic morning with JJ "metsa" Johnson, Goddess of Lichens. Interesting place I'd never been to just south/inland from Half Moon Bay.
