Button mushrooms

Can rabbits eat these?

no - no mushrooms of any sort are generally recomended although they are rumoured to be able to eat the deathcap and survive which is the most deadly mushroom to humans, I certainly wouldn't be testing it out on mine

That's great thanks. No. Mushrooms then

No no. Mushrooms are fungi and fungi are moulds. Many moulds secret mycotoxins which are fatal to rabbits.

This is the reason Depocillin cannot be given orally as it is derived from penicillin which is a mould. Interesting though it is the same mould (penicillium)which gives the white fluffy outer to brie and camembert.
