Debbie, thanks for these enlightening comments. I am not nearly familiar enough with Hebeloma species morphology to vote on IDs. I just meant to highlight that I happened to notice this group of observations appear as outliers and I think are worth highlighting to look into further (new discoveries await! e.g. wider known ranges or new species records).

To clarify my comment, I just meant that my H. dunense was a Hebeloma I originally identified as something else, but it turned out to be a species I had never heard of before, and maybe that will be the case here too. I did not mean to imply they are similar species in any way (sounds like they are not, from your research).

not to say that there might not be cryptic species hiding under insigne

but this obsie is certainly not H. dunense, which has much different macro.

A shame that you didn’t save this, Eva. And it’s been quite a while, but did you notice dark dropets on those gills? That is one more distinctive characteristic for this imposing and very interesting species.

I agree that it is still most likely H. insigne, barring macro identical cryptics out there.

Even Kuo has somewhat limited experience with insigne. Just because it hasn’t been collected and identified from more northern places (and it was indeed collected outside of the Rockies just last year, in NE AZ, by me) doesn’t mean that it doesn’t exist there.

Yes, Henry Beker will help to delimit just what sorts of Hebelomas we have here in NA, and he is very interested in collections of insigne, which I have promised to provide from AZ come this August.

As far as I know, this species has never been confidently recorded outside of the Rocky Mountains:

I realize just because it is only known from the Rockies doesn’t mean it might not occur elsewhere and was just never recorded. But Hebelomas are tricky. I know Henry Beker is working on North American species, so it would be worth coming back to these and consider other options; perhaps it is a new species or one not yet recorded here. For a similar situation see my Hebeloma dunense observation 267966
