So, what garden waste would be unsafe to use ground up as mulch

Living in a phytophthora-affected area I wouldn't use shreddings from
any host species.

That sounds reasonable.

The other day I shredded a lot of bramble and didn't mulch with it on
the theory it might grow from tips.

I suppose my line will be drawn at anything that might carry a pathogen
or will regrow.

I use everything, except plants that die under suspicious circumstances!
I don't put rose shreddings under the roses and I have never known
anything grow from shreddings so I don't worry about that.
Unlike Mike I am too lazy to compost I just put it all straight on the
ground
