Agree with the mushroom ID app that this is most likely either Burnt Knight (T. ustale) or T. ustaloides, but unsure which. Growing with beech. Cap was greasy (dry weather). The flesh is white and appears reddening (as per T. ustale) but I think the stem apex shows a sharply delimited white band as per T. ustaloides. It also has a reasonably strong odour that I wouldn’t describe as mealy.
