Another toadstool

I found these growing in one of my flower pots and very carefully removed them incase they are poisonous. But on researching them I think they might be Rooted Shank toadstools (oudemansiella radicata). Apparently they are edible but in no way will I eat any as I might be mistaken and I could never trust my judgement to eat any mushrooms or toadstools without the guidance of an expert.
(Until I was ready to upload this I was unaware that I had blipped them on this date last year)
