Thick base, sturdy fungi! About 10cm high 7-8cm wide. Didn't expect to see fungi in the garden at this time of year (especially as it's been so dry).
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.
Looks rather strange colour of the cap
I agree it is quite dark for A augustus but neither A vaporarius nor A silvaticus have the woolly stipe.
