Found in Dec 2015 on sand in and around Apodasmia similis, Pararaha wetland. Fairly common in a localised area of the wetland. We also found an exotic drosera (D. capensis) and at least 2 species of Utricularia. Suspect this Drosera was probably planted here.. Any thoughts?

Corticolous on tanekaha (Phyllocladus trichomanoides). Common. Thallus when fresh orange-green drying greenish-yellow to white. Perithecia aggregated in pseudostroma. Thallus K+ yellow, UV-. Ascospores 8 / ascus, irregularly arranged, ascospores 3-septate, 4-lcoular (22.5-)25 × (7-)8 μm.

First three images show lichen in-situ prior to collection, the other images are taken from herbarium specimen.

Seems to fit this genus and species best - but not recorded from New Zealand before.

Noted for Wharariki - Puponga Bioblitz November 2019.

Determination by A.J. Marshall & A. Aptroot - provisional, specimen sent overseas for further testing.

Noted once on the rawiritoa (Kunzea amathicola) twigs lying on forest floor. Images of re-hydrated and dry specimen.

Noted for Wharariki - Puponga Bioblitz November 2019.

Voucher: P.J. de Lange 14907 & T.J.P. de Lange, UNITEC 12263.

Abundant sedge of forest floor. Specimens fertile. Mature culms pendulous and/or trailing along ground up to 1 m from foliage. These mature fruiting culms often tangled together. Most seen had dehisced their utricles but all retained the glumes (a feature of this species).

Possibly - tentative determination by Dr Robert Luecking "S. kelica" - I will need to check spores etc.

Thallus silivery white but without obvious prothallus. Thallus covered in sorediate / pruinose orange-yellow pustules (pycnidia?). These structures K+ violet rapidly changed to black.

Common on pohutukawa (Metrosideros excelsa) in extremely dry situations - associated with Calicium tricolor and Chrysothrix xanthina.

Stirtoniella kelica - least ways as we understand it in New Zealand looks like this - https://inaturalist.nz/observations/13508617, https://inaturalist.nz/observations/19097349

Common. Foliicolous on karearo (Ripogonum scandens).

Thallus foliicolous, continuous, smooth, grey-white to greenish-white, without marginal prothallus, campylidia uncommon, glaucescent, orientated in same direction, apothecia black, weakly pruinose; hypothecium bluish, 40-58 microns tall

Abundant macro-lichen on the trunks and branches of tarahinau (Dracophyllum arboreum). Photobiont green. Medulla yellow. Thallus rounded with broad, rounded lobes. Upper surface green when wet grey-green when dry (as seen here), without soredia, isidia, pseudocyphellae or phyllidia, punctate-impressed,apothecia numerous. Thallus underside golden to golden-brown, finely tomentose, covered in numerous yellow, fleck-like pseudocyphellae.

Abundant in tarahinau (Dracophyllum arboreum) forest. Numerous shrubs and small tree's up to 8 m tall all copiously suckering from trunk bases and exposed roots in peaty ground. To date I have never seen a seedling of this species. Fruit is frequently set but doesn't seem to germinate in the cultivation.

Common in wasteland near Waahi Tapu (Owairaka Spring). Inflorescences umbellate, flowers mauve-coloured (an unusual colour morph in New Zealand), stamens 0.8-1.2 mm long, mature fruits scarce (and not shown here) but those seen with broad, reflexed calyces.

Voucher collected.

Corticolous on tanekaha (Phyllocladus trichomanoides). Ascospores hyaline, strongly apiculate, up to 250 microns (if the tails are included). Seems to key here using Galloway (2007), except ascospores hyaline not brownish.

Images and determination by Andrew Marshall on the basis of specimens collected by Dan Blanchon, Peter de Lange and Andrew for a lichen diversity study.

I am posting this here in case someone has any bright ideas as to what this lichen is.

Currently it is believed that Thelotrema monosporum is not in New Zealand (de Lange et al. 2012) and that specimens so labelled are T. saxatile but we are not clear if there is truly the case or not - the late David Galloway passed away before his thoughts on the matter could be formally published. The decision taken by de Lange et al. (2012) reflected David's unpublished views (David was a Lichen Threat Listing Panel member).

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.

A first for me, in that I have not previously seen this species in Northland (though I know it has been recorded from there).

A single windshorn tangle growing on cliff top. Admixed with Chenopodium trigonon, Coprosma aff. neglecta, Muehlenbeckia complexa var. complexa and pasture grasses.

Abundant. Corticolous on Fuchsia excorticata, Brachyglottis elaegnifolia, Coprosma tenuifolia and Griselinia littoralis.

Photobiont green. Medulla yellow. Thallus more or less orbicular, Lobes broad, rounded, upper surface without soredia, isidia, phyllida or pseudocyphellae; underside chocolate brown except for margins, these golden yellow; pseudocyphellate, pseudocyphellae fleck-like, yellow.
