Brief description
Characterised by verruciform apothecia with inconspicuous black ostioles, asci with 8 uniseriate ascospores, and by the presence of norstictic acid in the thallus.
Distribution
North Island: Kohukohu, Hokianga; Auckland (Kakamatua Inlet, Waitakere).
Habitat
At the Kakamatua Inlet site, Pertusaria endoxantha was only found on Phyllocladus trichomanoides, even though several other species of a similar size grow at the site, among them Agathis australis, Kunzea robusta and Hakea sericea. Other lichen species found on the same trees include Bactrospora arthonioides, Lepraria lobificans, Megalaria pulverea, Parmotrema reticulatum, Pertusaria psoromica, Pyrenula occulta and Thelotrema lepadinum. It has been also found on Populus sp.* in farmland in the Far North (Hokianga).

Ostioles black, punctiform, but inconspicuous in a hyaline zone 0.2–0.3 mm diam., 1–2 per verruca. Ascospores 8 per ascus, regularly or irregularly uniseriate, elongate-ellipsoidal to subfusiform, with smooth inner walls, 82.5–100 μm long and 30–40 μm wide.
