Some caution

The 3 Moser species found in NZ are quite clearly separated by spore data, and I have no doubt Mike has examined the spores and come to the right conclusion. However, one should exercise some caution here:
1) Two of the species were described from Borneo, and we cannot exclude some separate evolution in NZ. In fact, none of the holotypes has been successfully sequenced +published.
2) Moser examined the species in dried form, and reported sizes that are far below those found in fresh specimens, which is logical.

This said, the NZ concept of C. atrolazulinus does not cluster in the Violacei clade (section Cortinarius), but C. subcalyptrosporus does. All the nice characters (unique pigment, cystidia, cutis structure) may therefore be homoplasies.

The other thing that goes against this been C. atrolazulinus is the size and stipe your photo show a bulbous base which only C. atroviolaceus and C. subcalyptrosporus have. I have seen the purple Cortinarius from Kaimanawa and these grow to over 100 mm which is way beyond C. atrolazulinus size range.

The spore size, shape and ornamentation was a good match for C. atrolazulinus but we both know how difficult it is to separate the species in Cortinarius Subg. Cortinarius, I’ll leave it as it is at the moment and get Karl to look at it.

I spent a lot of time last season looking at these purple Cortinarius and would have said these were C. subcalyptrosporus. I found that spore sizes were to variable to key out with and found Q value to be more reliable.

The odd thing about C. subcalyptrosporus is that there spores should have a plage even when using Landcares microscopes I could see no evidence of this. Nor were there any collections of this in PDD to compare against my more resent collections.

Now I wonder what happened to the collection M. MOSER looked at.
