You could be right that it is C. caryotis (which is, in fact, a very common species), if it looks like Jerry’s picture in the link you gave. Also Jerry’s picture of C. pholiotellus is OK.

Thanks for your comments, unfortunately I don’t have a dried collection of this species but will make some fresh collections around April-June 2011.

I realize it is difficult to identify Cortinarius species from a photograph alone so I will make new collections to be sure, I suspect the lighting in my image has made the lamellae look lighter than what they really are so I have added an image showing the gills, they are more ochraceous than they look in my original image, and the pale yellow margin can be seen as described for C. caryotis.

I have seen your comment at my observation about C. veronicae, there are definitely no Nothofagus species in this area but there may have been a very long time ago, the climate this far north is not favorable for Beech, I suspect some of the species that are thought to only associate with Beech may also be able to associate with Leptospermum and Kunzea, I have found both C. vinicolor and C. veronicae in this habitat.

I have found one image that supposedly depicts C. pholiotellus but I am certain it is not the same as what I have, here is a link to that image.

This is a link to an image of C. caryotis which I think looks a lot more like my collection.

I think I’ll have to make fresh collections to come to a conclusion here.

Probably Cortinarius pholiotellus

The gills are too brightly coloured for C. caryotis, which tends to have dark yellow or ochraceous gills. Since Mike has many photos from Leptospermum/Kunzea habitat, I venture to guess that it is a question of C. pholiotellus, which only grows in that habitat and has bright, pale yellow gills. The former species only grows with Nothofagus. — In fact they are easy to separate on spore size, the spores of C. pholiotellus being much longer.
