Where can you get hold of some brown Mold.

[fictionfan]

brown Mold appears in the environment section of pathfinder website so I assume it exists. Does anyone have an idea of how to obtain it? Does it appear in any published adventure or other pathfinder material?

I'm not currently a DM. But brown mold seems to be to be a weapon of mass destruction that would make gods envious. I would sort of like to get my hands on some just in case I every want to freeze hell over or turn the plane of fire into the plane of ice.

Just get some of the stuff and a Remorhaz and you have an instant plot hook.
As to getting it that is entirely up to the GM far as I've seen. best method is trap filled places with the proper requirements to house the stuff and a clay jar to store it in.

Spoiler:

Well, an early chapter in Age of Worms features a patch of the stuff...
