Beech leaves stuck to cap - slightly depressed. Latex white and peppery taste. Dirty white decurrent, crowded.
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.
L.blennius is more a dirty grey colour, has distinct zones, pits on cap margin and quite mucifluous if memory serves me correctly. I wouldn't like to suggest an alternative though.
I have given it another go from my field notes...
This certainly has the LOOK of L.piperatus - pale cap. I grows readily in beech stands.
Did you use household bleach for test?
Shame on you not giving tasting notes! They are both very similar (taste) but I remember a 'delay' with blennius.
I think it deserves an agreement.
