S. brevipes

is associated with lodgepole pines, that’s why we all thought in it, right? But like Gerhard says it could be another one, because all Suillus are associated with conifers. I saw one that could match, but there is few information about it. It’s Suillus albivelatus.

Usually they are very particular.

But S. collinitus can be found with different pines and even with oak which I have posted, or with spruce.

My impression

is that Suillus species are very particular about their hosts. Are you sure about bovinus with lodgepole pine?
Anyway, I looked for a shortstemmed species that could grow with lodgepole pine, and found this one.. Could be others of course, but the colour is not a problem. Aged specimen can turn very pale.

Most Suilli

either grow with pine or with larch here in Europe and in Asia. In America there seems to be a broader range of host trees but also many with pines. It is in the group where brevipes does belong but I do not know which similar species there are by heart, I guess there are some five more.

Yes, I had thought in it too

everything matches except colour (with no mention of innate fibrillose)and the season (summer to late fall). I tried other similar but no one has light colors as this.
By the way, S. bovinus forms mycorrhizae with with lodgepole pines too, as I read.

Irene beat me to that again.

I just wanted to suggest brevipes myself. But keep in mind there are a few more short-stalked Suilli in your area!

I found this on the dunes, at Bluebill lake.
It is growing under lodge pole pine, on moss, in sand.
Since it was the only example, I did not pull it up, or tip it over.
It had a short stem… Short enough I couldn’t just lay the camera in the sand.
I have found many versions of this mushroom, on the dunes, in he short time I have been looking… (6 months or so.)
This is my first spring hunting mushrooms.

I agree that just Suillus is a wiser choice, I even thought to propose it, but I fell on the mistake of adding bovinus to the name. I still not sure of seeing innate fibrillose on cap, but admit it, and I think that’s the only feature which could rule out S. bovinus until now. And certainly bovinus is a more common specie here than there.

algoressister, please the stem is important, try catching it on your future pictures. What was the habitat here, trees nearby?

better photos

I will upload what I have…
I will go back and find it, and try again…
It is not THAT bad… Considering it was raining pretty hard. And I was sheltering the scene w/ my body.

Just look at the cuticle!

It is innate fibrillous like in collinitus and not uniformly colored as in bovinus besides the color is a bit different. Plus the pores are too bright.
Better photos of it would be a blessing though.

That is easy to understand, but what I wanted to know is: what features rule out S. bovinus, can tou explain me?

I voted down.

Because it is not Suillus bovinus ;)
This is close to collinitus I am not sure what they have there, maybe introduced, maybe indigenous American species. I would have to look through my literature but I am sure someone here will know what it is.

I mean

your vote on “Suillus bovinus”.

As if?

What do you mean?

Why “As if”?
