C. croceus on this board. The macro traits seem a bit diverse. I have been posting mine as “C. croceus group.” I should preserve some of my collections, in case someone ends up wanting to study this.

Dave, that would be interesting

if you have the same or a close relative to this species which isn’t close to croceus. There’s still a lot of investigation to be done, even with this little group of species.

These remins me of…

what I commonly call “C. croceus” here in Pennsylvania, USA. This type occurs under conifers; very common under spruce.

Moser suspected that olivaceofuscus and his carpineti (not a valid name) could be the same, but I think that the results of the sequences so far, indicate that more species can be involved.
MO obs 8210 shows a gang growing with Corylus.

Is this

what was called Dermocybe carpineti? Mycorrhizal with hornbeam and maybe oak and beech?
This I know from thermophilous oak-hornbeam forests from my vicinity fruiting during height of summer (June-September).
Are there more species involved???

not exactly the same after all..?

There’s a small difference in the sequences, and this was growing with Picea, the estonian collection with Tilia. And this is less green coloured than the ones I have seen in hazel stands. It’s also strange that it’s only a 95% match with the Tübingen collection in GenBank. Could be worth looking closer at more sequences of olivaceofuscus..

Right on

Others have agreed with that name — not that it matters much, but I think it is indeed C. olivaceofuscus.
