I'm trying to use the config option for blacklisting mobs from the prism, but it doesn't seem to be working. Same entity names work for the EnderIO soul vial blacklist. Any assistance would be appreciated.

Here's the relevant part of my config:
List of entities that cannot be spawned [default: ]
S:globalPrismBlacklist <
forestry.butterflyGE
mountainmobs.geonach
VillagerGolem
Botania.botania:pinkWither
>

edit: found the relevant wiki page for the odd entity naming scheme
