Good Evening All!

Hope everyone is keeping warm on this frosty night

, bitter here in Staffs.

I would like to post this as Boletus pseudoregius but would like confirmation. The pores, as you can see in the shot, have discouloured blue and there appears to be a yellowish net at the top of the stipe to cap.

As ever, many thanks for any help,

Jean

Hi Jean,

I'm going to have to disappoint you for this is no Boletus, but a Suillus species.
As there is a ring on the stem it is pointing towards S.luteus or S.grevillei.
S.luteus has a very slimy cap, sometimes with a hint of purple (note the colour of that 'bruising' of the pores) The pores are rounded, but those pores in your photo are angular (when the photo is enlarged) so despite the purple marking, I think you have S.grevillei - the Larch Bolete.

I do have some reservations though, as I see no sign of any Larch needles or cones in the photo - was there a Larch nearby, also, there seems to be more of the stem ring remaining than I would expect for Larch Bolete and so that would suggest Slippery Jack. I really am having trouble interpreting this one.

Neil.

Hi Neil,

No Larch to my knowledge and although I looked up Larch Bolete at the time it didn't mention anything about a yellow net at the top of the stipe...but I did have my reservations re:Boletus pseudoregius as the size of the cap seemed too small. Do Larch Boletes have a yellow net or is that just a 'something' left over?

Regards, Jean

So can you remember what trees there were ? I can see leaves - are these Sweet Chestnut ? Larch Bolete is specific to Larch and Slippery Jack is specific to Pine, so this is turning into quite a puzzle.

I think you are misinterpreting the meaning of the word 'net' - what you are probable looking at is decurrent pores, the equivalent of decurrent gills which run part-way down the stem.

This image was taken about 4 mins after ... so in more or less the same vicinity re: trees. In that area there are Pine, Beech and Oak trees, mostly Pine...and near to the lake. Any help?!

It is difficult to know what to think - you say mostly Pine, yet in both photos I can only see leaves of broadleaved trees.
But mostly Pine would now tend to suggest this must be S.luteus, but I remain undecided as to which Suillus species this is.

Sorry for the confusion

...What I meant to say was it's an area of both broad leaf and pine. Broad leaf towards the lake and pine further back and away from the lake. Where these fungi were situated would be oak, beech, laurel, birch....

I see no Larch but I am pretty sure I see S grevillei so there must be at least one in the area.

Phew ... Thanks for the back up Mal, thought I was beginning to loose the plot there for a minute.
There are other more rare Suillus spp. with a 'ring' on the stem, but most of these are associated with Larch too.

I should have had more faith in my first instincts for after Jean said no Larch, I was really worried somebody was going to come straight in and say it is so obviously Slippery Jack (without paying any real attention to the angular pore mouths).

Thankfully Jean, the detail in the photo showing the underside came up really well.

Hello Neil and Mal,

Many thanks for all your help and also for teaching me another very valuable lesson

...TAKE A SHOT OF THE TREE ETC, RE: SUBJECT IS GROWING BY!!! I really must not rely on my memory, I don't think it's as good as it used to be

. But I'm going through my photos again I found this at the side of the lake....

just a couple of minutes difference in shot time according to my photos. I didn't think about the tree, just the unusually shaped bracket...'can't see the wood for the trees' should read, 'can't see the tree for the fungus'

!

Getting back to the Suillus grevillei, it's been in my 'sort' folder since the end of October. Such lovely colours and texture...I'm so glad you guys sorted this for me but I think I took you all around the Wrekin to get there...sorry

!

I've got me thermals on

for a walk to the lake...bbbrrrr, so cold!

Best regards,

Jean
