Iodine Bolete

[Bill S]

Hi folks

Saw some early boletes over the weekend, and the previous weekend. All on clay soil in mixed woodland with plenty of Oak about. Can anyone confirm whether they are iodine bolete, Boletus impolitus, or suggest alternatives if they definitely aren't.

I didn't pick or slice them to establish bruising properties as I wasn't sure they weren't something rare.

The second of the two had a darker cap than the first one and was growing at a strange angle allowing the underside of the cap be shot.

Many thanks in advance

Regards

I can tell you that the first of your finds is not Boletus impolitus. I am fairly sure it is a pale example of Leccinum versipelli the Orange Birch Bolete. The second I am not quite so sure about. It might just be B impolitus but without more information it is difficult to be sure. Its' common name is the Iodine Bolete and it has a very distinctive smell especially in the base of the stipe when you cut it in half. This would also show the bright yellow just above the pores and often just inside the outer edge of the stipe.
Here's one I found earlier (yesterday)

Hi Mal

Thanks for that, as I said I was tentative about taking one to cut because I wasn't sure about their rarity and there are some Red list bolete species. The stem doesn't look scaly enough for Leccinum versipelle.

Thanks again

I think your first species is Leccinum crocopidium, I can see around the edge of the cap and where the flesh is broken that it is darkening, which is characteristic of this species. I would say that the second picture is of a different species, possibly an immature B appendiculatus, as the margin of the cap projects beyond where it meets the pores. In your picture the margin curves under. Did any bruising take place with this darker capped specimen?

I now believe your darker capped specimen to be in fact just a darker capped Leccinum crocipodium as this species can vary from a cinnammon coloured cap to the lighter cap in your other picture. Interestingly I recorded my first of this species today with Oak.

Thanks Andy, as neither suggestions seem to be rare, if I go back there this weekend I may pick one or two for further investigation.

Cheers

Understood, I should have said I was in the South and this was seen in the New Forest. May investigate more at the weekend if I get the chance,

Thanks again both
