Collection location: Kaimanawa Forest Park, Taupo, New Zealand [Click for map]
Who: Michael W (Michael Wallace)
Notes:
Although this species closely resembles the South American species C. magellanicus molecular studies have shown that it is closely related to C. cycneus and is possibly a form of that species, I find the species belonging in Cortinarius subg. Myxacium group “Pallidi” to be the most beautiful in this genus.

Yes, as you say, it has been shown by molecular markers (unpubl.) that C. cf. magellanicus (the one found in NZ) is closely related to, if not just a form of a variety of, Cortinarius lubricanescens. You mention C. cycneus, which is also closely related, but is clearly a distinct species.
The true C. magellanicus is described from, and grows in, Patagonia, Sth America.
They were in a small crevice on a near vertical dark coloured clay bank, there may have been some very rotted wood nearby but the fruit bodies were in the clay, I did see quite a few corts fruiting on top of very rotted fallen Beech trunks that were covered in moss but the wood was so decomposed that I would say the fungi are not truly lignicolous!
This species is rare and I was very happy to find it but it was rather difficult to photograph due to the rain and dark conditions.
I mentioned the beautiful species belonging in Myxacium group “Pallidi”, Karl doesn’t list this species in that group in his book, he places it in Myxacium group “Delibuti” but molecular study has proven that it is closely related to C. cycneus which does belong in the “Pallidi” group, I’ll have to ask him more about this when I meet him next month to study the Cortinarius that associate with the Myrtaceae forests.
those on wood? If so, is this species typically lignicolous?
You sure do get some colorful fungi down in Kiwiland.
