marshy's Identifications

Common. Corticolous on inihina (Melicytus chathamicus) and taupata (Coprosma repens).

Thallus dirty white, grey, lumpy but otherwise smooth and not cracked, apothecia 0.5-1.2 mm diameter, sessile or immersed, brown (not black as is usually the case for this species in New Zealand), rounded, subangular, radiating or stellate.
Ascospores 25 × 10 μm, colourless, ovoid-obovate, 5-septate.

As currently circumscribed for New Zealand Arthonia peraffinis is a variable species, especially with respect to apothecia size, shape and colour (brown or black). New Zealand "Arthonia peraffinis" would repay further taxonomic investigation.

Voucher collected.

Determination by A.J. Marshall.

Saxicolous on Te Whanga Limestone. Abundant - probably the most common saxicolouys lichen on limestone on this island. Apothecia variable many grey-pruinose, otherwise agreeing with description of this species in the New Zealand Lichen "Flora" series.

I+ blue hymenium. Dark, 1 septate spores around 12 x 5 microns. Convex apothecia, rimmed at first then lacking at maturity
