help identifying boletes please

Hey all, found about 8 of these dotted around a birch woodland about a month ago. Think it's the orange birch bolete, leccinum versipelle, but not sure if all are?

The spongy pores bruised brown after about a minute of handling. the stipe was white and had black dots and was peelable.

the pores were yellow

growing on grassland near heather and dead wood (birch most likely)

could these two be the same as the above, although they have a brown cap and not a bright orange one?

thanks for any help! Joe

The third photo down, seems to show brown scales on the stem, yet you say they are black ?
We need to clear this up before we go further.

Hi
Your first is Leccinum aurantiacum and the second is likely to be L scabrum.

I must say this is beginning to sound like the Orange OAK Bolete, Leccinum aurantiacum, but you say "dotted around a BIRCH woodland" - any chance of twisting your arm again ?

Neil.

EDIT: Grrr... There's me, trying to be methodical like Ken, and Mal, fresh back from Clumber, jumps in and beats me to it - I hate you Mal. (a big 'grin' emotocon is supposed to go here, but these are not available when editing)

It was a strange area really, it used to be scrubland, quite marshy up until recently now a lot of birch trees growing, but the undergrowth is covered with lots of dead wood, i assumed was birch but could be anyhting, certainly plenty of oak trees in the same common!

appriciate your input on this by the way

Concepts have moved on based on DNA analysis. Leccinum aurantiacum is now considered to have a range of mycorrhizal associates according to den Bakker and Noordeloos:

'Mycorrhizal with Populus, Quercus and Betula, rarely with Salix, Fagus, Castanea and Tilia'

Cheers Ken, so there's more to it than being 'methodical' - one has to have a super memory as well !

Ken,
Has L.albostipitatum now been lumped in with L.aurantiacum as this is supposed to look similar except for its association with Populus (including Aspen).

No. Leccinum albostipitatum starts off with a pure white stem and has a brighter orange cap. For a fuller discussion of the differences, see the following website:
