Holotype: New Zealand. Westland, Gillespies, Cook River road between Tornado Creek and Whelan Creek. R.C. Harris 6241 – MSC.
Description : Flora (1985: 532 – as Sphaerophorus macrocarpus). See also Tibell (1987: 229) and Wedin (1995b: 59–61; 2001a: 8).
Chemistry : Medulla K+ yellow, Pd+ orange-red; containing sphaerophorin (major), 7- O -methylnorascomatic acid (submajor or minor), stictic acid (submajor or tr.), constictic acid (minor), cryptostictic acid (tr.), isousnic acid (tr.), placodiolic acid (tr.), 4- O -demethylsphaerophorin (tr.).

Bunodophoron macrocarpum is characterised by: the corticolous habit; the large, globose to subglobose, flared apothecia, and the broadly flattened, subflabellate sterile branches. It is similar to B. scrobiculatum, which is generally larger, has larger spores and a different chemistry. B. scrobiculatum often has a more grey colour with a frosty pruinose tinge on younger parts of the thallus, and with supporting branches that are usually not so long and distinct.
