Just double checking this is amanita muscaria, picked on a wet day in pine forest in Ireland. A bit eaten past its sell by date
Your mushroom looks like Russula sp. In the future for more reliable id you should also show a picture of the stipe, underside of the cap, how the stipe attach to the cap, and spore print.
Still Russula IMO, could be R. emetica. C0mpare with the description here Russula emetica - Wikipedia
The photos don't provide enough information to be sure, but I don't think that it is a Russula. I see lots of slug-chewed Russula caps, and they invariably look white under the chewed off skin, never yellow as shown in the photos. Also, I see a few white flakes near the edge of the cap top, which could be the remnants of a universal veil that are characteristic of some Amanitas. And, in the first photo, the stem fragment appears to have ornamentation that resembles the concentric rings found on some A. muscaria. However, a clear photo of the entire stem attached to the cap would be needed for a more positive ID.
Hi Folks, Looks like Amanita muscaria with the white veil remnants washed off the cap. Regarding other possibilities suggested: Note that R. emetica is very rare in our region, so though possible if this had been a Russula, there are other red-capped species that are more likely. Amanita caesarea does not occur here. Noting region can be very important for narrowing down identification. Some species are transglobal, but many are known only from certain regions or to specific parts of the planet. This can be particularly important from a safety point of view when folks are considering edibility or medicinal uses. - frog
I know little of the fungi of Ireland personally, but I see the range maps northern limit for A. caesarea is quite a bit south of there. Perhaps someone from that region can weigh in on logical species options? The veil remnants point to Amanita muscaria but there may be other species possibilities for the UK.
I do think it's a Russula but there are several Russula species growing in Ireland and the British Isles. Two that come to mind that have the similar shade of dark red on the cap and can get that yellowish tinge to them under the red (presumable oxidation from exposure to the air) are Russula rosea, aka Rosy Brittlegill - and Russula roulette.
Thanks everyone for your help on this. I have found a few more today while out walking, and one also a smaller one that looks a bit different. There has been less rain recently so it appear that the white spots are still on, a lot of deer as well in the area. This is Co Galway Ireland BTW. I am trying to learn on my own about all the varieties of mushrooms on a forest nearby were I live. I am particularly interested in medicinal and of course the edibles. It's been very wet.
It is Amanita muscaria this time Fly Agaric (Amanita muscaria) | Ireland's Wildlife. The mushrooms on your previous pics look different though.
Note the same yellow colored flesh where the top skin has been scraped away in all three sets of photos.
Thanks guys I appreciate your input, I've lots more photos of species I have found. And the small one in my hand is it something different?
Oh, I just noticed the hand in the last set of photos; my comment about sameness was based on the hand in the first set of photos. I agree that the middle photo in the last shows a Russula, but identifying the species of red Russulas is notoriously difficult.
