in coniferous woodland
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
Yes this is a Russula species. I am pleased that you photographed the underside and gave a clue of conifer wood as its habitat. I can only take a guess at the species. Because it does not have a flush on the stalk similar to the cap colour it must be somewhere near The Sickener Russula emetica. I would need more information to pin it down.
Brittlegills are awefully tricky to pin down to a species sometimes I find. Especially the purple/red capped ones. There are so many that look alike. It could well be the Sickener, but I daren't take a nibble to find out!
One helpful hint in identifying Russula sp is to ascertain how far the cap peels if any, eg none, a quarter etc. I am studied fungi for over 50 years and I am now in my late 70s. I try a small piece of Russula emetica when I am uncertain of the species. Just chew a very small piece for two seconds then spit it out. Do not chew until the effect is felt. It is a common occurrence to taste many species but you need to know which are dangerous.
