Spore Blossoms Should Impact Mushroom Growth

I think that mushrooms planted in the area where a spore blossom emits its particle effects should grow more easily.

Currently there is no functional purpose to finding spore blossoms. This would make mushroom farming easier and give players a practical reason to seek out spore blossoms (and pillar up to retrieve them). Also, the link makes sense because real world mushrooms spread through spores.

This could slightly increase the chance a mushroom has to spread each tick, give it a probability of growing into huge mushroom instead of spreading (this would be particularly interesting as there is currently no way to grow huge mushrooms without bone meal), increasing the light level at which mushrooms are able to spread, or something else.
