Bolete with pink pores

[Ken Burgess]

Found growing today in grassy soil under oak near Mobberley in Cheshire. The photos probably don't do the colours justice but the pores of this bolete are a vivid pink. Not orange, not red, but definitely bright pink. And the flesh does not turn blue on cutting. Flesh in the stem base a golden yellow.

The specimen was fairly immature but someone had kicked it over, which is why I noticed the pores. Cap diameter about 20 mm. Anyone want to offer any suggestions?

Hi Ken,
I'll have a guess from my inexperienced perspective at Bitter bolete, Tylopilus felleus, but I bet you've thought of that and dismissed it..................!
pink pores not bruising blue and pink spores showing, I think, on the stem?
Just a colouring variation?
Interesting.
Cheers

That's a good suggestion but the flesh of my specimen tastes pleasant - no bitterness at all (although this isn't diagnostic), and the pink colour is actually the colour of the pores rather than the spores. Tylopilus felleus starts out with pale pores which turn pink as the spores ripen.

I don't think my specimen is mature enough to produce any spores, so the vivid pink colour isn't related to spore colour. The pink pores are decurrent onto the stem as a network and the stem is flushed the same pink colour at the apex.

Also T. felleus doesn't, to my knowledge, have the yellow flesh in the stem base.

This is Rubinoboletus rubinus. A relatively small, beautiful yet uncommon species with those eye catchingly coloured pores. The bright yellow in the stem is also a good characterstic. It is most often with Oak.

Thanks Andy. That was the conclusion I came to but I just wanted a second opinion.

I think it must be a good year for it, because I confirmed a more mature specimen from a photograph posted on the Manchester Wildlife Fungus ID Forum. That one was found in Worsley Woods in Greater Manchester.

This is one of my all time favourites. I was shown it down in Windsor some years ago by Alan Hills and I have been looking for my second sighting ever since. I may need to follow Ken across the pennines.
