What ring?

I have no idea what a ring of toxic spores is but if you are asking where and when toxic spore nodes are spawning then the answer is everywhere at anytime. Those nodes are random. 1 always spawns after a toxic spore event and the others can be around that area but are not limited to that area. Many maps have spawns of random toxic spores for you to gather.
The 5 or 6 toxic spores that don’t give a guaranteed rare quality spore are spread around most of the zones. They have a fairly quick respon and always appear at the same spot.
