Growing under birch.
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.
Not sure that it would be A. muscaria as I think red colour remains even after heavy rains. Possibly another Aminita . Any smell when you bruise cap? Did you measure cap and stipe length and diameter?
The more I know the more I realise I don't know
I also thought the colour stayed after rain. Having said that the cap was faintly red - a bit more than the photo suggests - and there was another Fly Agaric less than a foot away with its colour still present. The cap was approx.12cm and the stipe 10cm high by 2cm wide. I did not try bruising the cap.
Maybe the blusher would be a nearer match for this colour cap. Not really enough information to make a outright identification.
Blusher certainly grows on the site, but there were not any others in the immediate vicinity.
my initial impression was A rubescens too.
