Tis the season to see Fungi, fa la la la la....

Taken just now (so a few hours apart):

 

 

The tube layer and pore surface really are very very yellow. Upper fleshy layer is a paler yellow (slightly chalky yellow).

 

You can zoom in on the photos.

Warty cap is throwing me.

 

No books here so your on your own.

No worries, David. Any other forums that may know?

[Jake Andrews]

Iv also been trying to look it up but to no avail. I'll keep trying.

[Kveldssanger]

Some images on the net suggest it may be Boletus aestivalis (though the cap texture seems to vary markedly).

 

EDIT: Just ralised this is B. radicans! Hahah.

 

Otherwise maybe Boletus porosporus?

Talked to a couple of people (including my tame mycologist) and they felt it was more than likely the iodine bolete - Hemileccinum (Boletus) impolitus.

 

Based on time of fruiting and the yellow pores it would be either Boletus radicans or the above. As it didn't stain they believed that impolitus was the best fit.

 

It's common name derives from a distinct smell of iodine from the base of the stem.

Confessing that I don't know what the smell of iodine is like from the top of my head, nor what some industrial roadside grass verge with a bolete popping out from smells like, I couldn't possibly comment on the smell!

 

I had a look at some images of the iodine bolete and the upper cap surface does seem a little similar in a few images, though it's a lot more smooth in most (assuming internet searches provide correct identifications).

 

Thanks for putting the extra time in talking to others on this one, and thanks to those other people as well. Much appreciated. Really cool fungus!

Cap morphology can be affected by a number of things paticularly in development.

Temperature, virus, parasitism etc....

Not always a solid I'd feature.

 

I've learnt that it's more useful to hone in on the core markers like pore/gill type, species association, spore colour, smell.

 

 

At first glance I thought your example was an Amanita, as I've seen the solitary Amanita (A. echinocephala) look very warty like yours. Iwasn't until I saw the pores/tubes that I realised it was a bolete type and the oak was then a good indicator towards radicans. The staining was the key on this one though.

 

Geoffrey Kibby (who agreed on your one being H. impolitus) wrote a great book on the Bolete genus which is well worth the investment, as are the Russula and Amanita versions.

Interesting. Will mark those down to acquire in the coming months. Will pick up a few of those ones from Summerfield. Cheers.

Loads of stuff popping up at my local park .
