Will mushrooms, 'fungi' hurt other veggies?

[zeroma]

I've been collecting mushrooms that just pop up in the lawns around my house, put them into a 17 gallon Rubbermaid storage tub along with some other bits and pieces of found green and brown compost making things, small twigs, green and brown foliage, pine cones, bark, adding spent coffee grounds and I have been adding some half finished compost.

I covered it in a warm garage and volia, I had more mushrooms!

Since I wanted the mushrooms - thinking it would help break down my small twigs, barks, etc now I'm having second thoughts. What if the mushrooms I've picked are poisonous?

Since this compost is going to be used in raised beds eventually, will it hurt anything I grow in this bed if some of the possible poisonous fungi pop up? Will it poison cabbage or onions or lettuce growing in the same soil?
