This one is said to be found under P.silvestris and mugo
on moors, moorland woods …Alps to Lapland….

according to Moser Meinhard’s book of keys

What’s growing with Pinus contorta?

I have seen S. flavidus, of course, but not in the alpine region.
This reminds me that I have to check and see if there are any in the many contorta plantations up north. Which one would it be if I find some there?

thrice, all localities in Czech Republic in sphagnum bogs altho the species is fruiting in Austria too; but the places in Austria are always without fruitbodies when I visit them – I think it is just getting too dry already here :(
I’ll post photos when I come to them one day …

I didn’t know either, haven’t seen it myself, but that’s what Henning Knudsen & Andy Taylor writes about it in Funga Nordica…

grows in dry habitats too? Never heard of that. In Central Europe you can just find it in swamps with Sphagnum and Pinus or in very very very wet pine woods …
And just from the photo I would consider this S.umbonatus.

and S. umbonatus were at a time considered the same species. They have been checked with DNA-tests and found them close, but different… and neither MycoBank nor Index Fungorum make them synonyms.

The cap colour on our Suillus flavidus can vary a lot, from bright yellow to yellowish brown or dull beige. For all we know, it has a wide range of hosts and habitats too, best known with pine in damp forests, but also on dry heaths and in alpine areas with Arctostaphylos.
According to the links above, both flavidus and umbonatus occur in North America.

according to David Arora Mushrooms Demystified
it is yellower or the same species

Suillus flavidus?

I believe I read somewhere that it is thought that S. umbonatus is the same as S. flavidus of Europe… I can’t remember where I read this… Any insights?
