All passive animals needs grass to spawn from a spawner. I'll say it's intended.
All "normal" passive animals spawn on grass anyway, but mooshrooms are an exception; they spawn on mycelium. So ... I'd say it is a bug.
Still a concern in 1.5.2. Mooshrooms only spawn on grass, it is a bug in that mooshrooms are only ever created during initial chunk generation. If you kill all the mooshrooms in a mushroom biome then no more will ever spawn.
To solve this you have to use a silk touch pick to get grass blocks from outside the mushroom biome or build a dirt bridge to it so that grass will spread. You must then remove mycelium and replace it with grass blocks to create a "spawning pad" where mooshrooms can spawn.
Mooshrooms should be able to spawn on mycelium, but they do not.
Is this still a concern in the current Minecraft version 1.7.2 / Launcher version 1.3.4 ? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
Yes, this is still an issue in 1.7.2.
Still an issue in 14w08a
Is this still a concern in the current Minecraft version 1.7.9 / Launcher version 1.3.11 or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
Confirmed for 14w17/18a.
This also applies for random natural spawning (without a spawner). On grass on a mushroom island Mooshrooms do spawn - On mycel they do not. Definitely a bug.
