Yeah, that is unfortunate for you when you run into a stack's radius unknowlingly, but then again, the animist had to spend a lot of time preparing and maintaining that stack of shrooms.
I'm not sure there is anything a caster can do to prevent being insta-killed if there are enough shrooms there (would guess all 15 would be needed on people with decent kit) and he's the only target.
When people talk about not being able to do anything when a shroom field "appears", like cretien did earlier, I am very sceptical though. Each shroom takes 3 secs to cast (and that assumes all anis are in decent kit, the base cast is 5 secs) and does 100 damage every 3 seconds to 1 target.
Now ... say you've got a force of 30 Albs, they've got a 1 in 30 chance of being hit for every shroom. It would take 3 animists 30 seconds just to get to the point where everyone is taking 100 damage once every 3 seconds. If there was an unsually large number of animists in the Hib force (assuming 30 defenders) ... say 6 animists (which would be 1 in 5 defenders as animists and I've never seen anything even approaching that before) ... it would still take 15 secs to put enough shrooms out to average an interrupt on everyone once every 3 secs. Some unlucky people who got randomly targetted by more than one shroom would take more damage, but I can't see how it is gonna make holes in your force more quickly than you can move away from the shrooms and either nuke them down or get some intteupts on the ani so the shrooms expire on their own.
The real situation is that shrooms kill people because there are OTHER defenders as well making OTHER areas no go areas. This creates little killing grounds in which the shrooms can find a relatively small number of targets and hence have a large impact on those targets. But even then the people don't have to just stand there and take it.
