I asked about vegetarian cheeses in Italy before I went on my trip there, and found this excellent list:

But I found it really difficult and annoying for the people around me to try cross reference brands and types while standing in front of the fridge in the shop, so I took some pics of some cheeses that are acceptable for vegetarians for fast reference, in case it might help anyone else trying to do the same thing. This is in no way an exhaustive list, but when you are standing in the tiny aisles while an irritated Italian is behind you trying to reach around and get their own shopping done, you will be glad to be able to grab something and leave:
