The white ones seem to resemble many features of Hygrophorus fungi.
Definitely be careful with these. A good few are edible, but they are tricky to Identify and have plenty bad lookalikes.
From what I can tell by the image it's a type of club fungus.
Possibly..? https://en.m.wikipedia.org/wiki/Clavariadelphus_truncatus
Either way I haven't seen those before, very interesting!
