I have eaten these (wine caps/rugosoannulata) alot recently and they taste good, no ill effects. Most of the ones coming up and growing huge are the albino form which has a stronger smell and flavour.
I have heaps of Wine Caps (Stropharia rugosoannulata) growing out of woodchips around here (SE QLD) at the moment. Been eating them. Most of them have been the albino/alba form which have a more earthy/stronger flavour. If anyone wants prints or some mycelium filled chips let me know.
