Hi Vladimir,

we are talking about North America here. It’s not relevant what we find in Europe because here everything has been cleared.
But in North America there is still much work to be done.
And no, this is neither versipelle nor aurantiacum in my book. At least not in the original sense.

I went out to find some, and:

I made an observation, found quite a few yesterday (4 of them). I did my best to explain the differences that set it apart from another apparently related species that i pick and eat. I also found a few of those a while ago, i might go out today to find one and take pictures since i know where to find them. I have some samples in the freezer but i am not sure if they will last too long, since i am hungry. :)

Not enough information to determine species

It seems to me that we do not have enough information to determine the species of this observation. We don’t know the bruising reactions of the flesh or the pores or any micro characters. The stipe scabers of L. versipelle are said to be dark brown or black by both Watling and Den Bakker.. so it seems unlikely that this could be L. versipelle. While this observation could not be L. aurantiacum as defined by Den Bakker.., it would be possible as defined by Smith and Thiers or Bessette, Roody..If those of us that belong to Societies or Clubs that provide scholarships would pool our funds perhaps we could fund a study that would straighten out this mess that we find ourselves in as it relates to Leccinum taxonomy in North America. Any graduate students out there interested?

I couldn’t agree more, Gerhard. Leccinums are an impossible to ID and poorly known group.

I have no idea about the things in North America

but in Europe it certainly does not fruit with conifers. Conifer symbionts here are only L. vulpinum and L. piceinum and possibly a third as of yet with no name.
Leccinum in general is a very difficult genus and I am still not 100% able to distinguish the many brownish ones with birch in bogs and similar habitats. Also I think there are too many names out there. Although I have to say in the same time that I strongly disagree with Noordeloos/De Bakker who reduced the species number to more than it actually is. Leccinum is still poorly known and many dealing with boletes still shun them. As to mycorrhizal partners, occasional exceptions to the rule can be found within many genera but this is only aberrant or out of need if there is a suitable environment but not the right tree or the partner had been cut and the mycelium tries to survive with a similar or related tree species. But it is also possible that we still do not know sufficiently about their relationships because they are so easily to be mistaken.

if this had been collected in Europe, I’d agree with you.

Certainly, we are close to being on the same page here. Apparently vulpinum and aurantiacum and manzanitae are all closely related. L. aurantiaccum is known to be one of the rare Leccinum species that appears to have a variety of hosts, both hardwood and conifer, or perhaps we are just not able to separate out these species differences in hand. Ya think?

The Leccinum aurantiacum “group” works for me, at this time.

Mycorrhizal with pitch pines?
By: Gerhard Koller (Gerhard)

That would fit (European relations) for Leccinum vulpinum which grows with common pine (Pinus sylvestris) …
L. aurantiacum (European and original version) grows almost exclusively with aspen and in some cases apparently with other deciduous trees but never with conifers.
Overhanging cap margins can be noted by many many Leccinum species. I wouldn’t rely on that.

sterile flaps…

are indeed present on our version (as well as the European version) of aurantiacum. Check out this link:


That said, getting Leccinums to “good” species is not easy, even when you have the bolete in hand and a Bessette (not just their book) by your side!

But at this point in time, an American version of L. aurantiacum seems to be the best choice.

Nice find, Martin. Out here in the dry CA west, we have plenty of fire and not so much fungi. :(

Thanks Vladimir and Herbert

Definitely take a look at the link to Kuo’s pages in IG’s comments below. I like what he says.

I eat these too

Found some lately near my home in Romania, did not create observation yet. They are almost common here i would say, seen and ate quite a few to date. I will create an observation too when i will get a nice picture of them.

Thanks Danny

I just read IG’s link to Kuo – it is much more extensive and detailed than most of the entries on his pages. Very interesting…,

I would like to see a large fruiting.

This is the 1st one I have come across and despite the photo, it seemed about ready to rot.

This beautiful and wonderfully edible Leccinum species (I dry it for future use in soups; it can also be marinated/pickled) grows in association with pitch pines in the sandy coastal plain of NJ. It’s a fall bolete that usually peaks here in NJ in the first half of October. In certain years, it can grow in prodigious numbers. Last year, there was an early fruiting in August, followed by a second one in late October, just a week before the Oct. 29 snowstorm. We, in NJMA, call it L. aurantiacum, too, but it’s likely to be a misnomer. Read Michael Kuo’s discussion at http://www.mushroomexpert.com/....
