All found today: -
No.1 Any thoughts on this crust? - Growing on a fallen/rotting trunk.
Overall size of first image about 300mm wide.
I'm thinking possibly Wrinkled Crust -
Phlebia radiata, as I have found that near this location previously. (Although more developed & more pink coloured).
No.2 Could these be Deathcaps -
Amanita phalloides?
Growing under Birch, satin-like "sheen" on caps, large volva, no veilar remnants on caps.
Cap diameters about 70mm, stipe heights about 120mm.
No.3 Originally thought this was a young
Armillaria mellia. However, on looking at underside, no ring, but very copious amount of grey veil-like "web".
Found on a moss covered rotting log under Birch. Cap about 50mm across. Stipe about 70mm tall.
Could it be Scaly Webcap -
Cortinarius pholideus?
No.4 - I think this is a large Deer Shield -
Pluteus cervinus, but much larger than I've ever found previously.
And finally, just because it's only the second time I've found any.

Green Elfcup -
Chlorociboria aeruguinascens.
Any help with ID's much appreciated as usual.
Regards,
Mike.
