Boletus sp.?

[oxycera]

Hope someone could have a stab at this. Is it Boletus scaber?

[NickCantle]

Difficult to say what it might be. I've seen the pores of Leccinum scabrum do this- the trouble is, I can't see the stem well enough to gather characteristics of L. scabrum. Probably is that though, but can't be sure

[oxycera]

Thanks Nick.

[Steve Wurzel]

Also check Porphyrellus porphyrosporus, as far as I can see there is nothing to exclude it from the info you give.

[NickCantle]

It's much more likely to Be Boletus Badius if Porphyrellus porphyrosporus is being mentioned. They're very similar with the exception that Porphyrellus porphyrosporus has a faint purply tinge to its stem and its cap. Plus, P. porphyrosporus is rare. I'm not saying it's not it, but I've never seen it, nor heard of anyone that has. I'm not sure that Porphyrellus porphyrosporus still a synonym either, not a clue! What other species are in the Porphyrellus genus or is it another oddball?

I still think it's probably Leccinum scabrum

For England it is the only Porphyrellus (see Basidiomycota Checklist-Online - Country Species List ) but there are about 40 internationally (see Porphyrellus - Wikipedia, the free encyclopedia ) I only suggested it because I found a matching photo in my archive and couldn't exclude it.


I think your probably right about Leccinum scabrum but like you I just can't see enough of the stem detail to be sure

[FungiJohn]

I hope oxycera doesn't mind but I've altered the background information to give a little more detail to the stem / pores



It looks a bit past it to me.

[NickCantle]

Did you up the saturation FJ? It looks way more red- couldn't that throw off the possibility of an ID?

No Nick, just the shadow / highlight detail.

A cross section would have been useful.

John

[NickCantle]

Aha, maybe it's bringing out red. Odd! A cross section would've been ideal, you're right.

Get back down there Oxy!

[oxycera]

It's growing behind my house on the side of an old slag-heap. I can go tomorrow afternoon and do a x-section (but is it too far gone?)

[Fungus Ken]

Yes, I'd say it's too far gone, judging by the sogginess of the tubes.

To be able to identify Leccinum to species you need to see any colour changes in the flesh when it is exposed to the air. Old mushrooms may have unrepresentative colour changes, both in the external appearance and the flesh, which can lead you up the garden path.

For a while this genus was split into a larger number of species based on nuances of colour but the DNA evidence now suggests a reduced number of species, many of these subtle differences in colour not being correlated with particular species.

Many thanks for all the help

A close up of the stem and pores would be useful, I set my camera to "tulip" focus for close-up shots, but manual focus if you don't have a close-up auto-focus.. we need to see the detail.

Hopefully it will take a cross section, usually it is the best way to ID Boletes. Althouh a quarter section will give enough information for most IDs, leaving the donor still standing and functional, useful for ID'ing a pristine solitary funghi, without totally destroying it.

One I prepared earlier


Quarter section..


Removing a section of the pores from the cap will help confirm an ID of Boletus luridus..

[oxycera]

Thanks Steve, the least I can do is have a go since you've gone to all this trouble.

[Steve Wurzel]

No Problem it's all from another post

Just for info, I've just sorted a Boletes Species list for England (only), simply to check where my archive has photo's short and to clear out non-English species.

This is based on the total Kew 2006 list of English Basidiomycota. and selecting just the Boletes species I can identify (excuse the "No Photo" comments, that's just my notes)

I'm not sure if it's of use to anyone but I don't think it's a readily available list anywhere, and should help with IDs..

Is this any better, a nearby specimen.

Nice to be able to give something back to you for me being so shoddy ay hoverflies

Glad I went back to photograph the second specimen (I found a White-letter Hairstreak on the way - see Butterfly gallery). Time I scuttled back to my comfort zone on the Insect Forum, fungi seem to have got more complicated since I first had a go c.25 years back.

[fairplay]

Um....er.....Leccinum scabrum ?

Has anybody noticed that slight bluing at the base of the stem ? Me thinks that makes it something else.

Neil.

[NickCantle]

I knew you'd ruin it for me I couldn't/can't see any significant staining. This, to me, looks like a typical Leccinum scabrum.

So there
