Mycanid said:Historically, the first place they popped up was in 1e ADnD module A4: In the Dungeons of the Slave Lords.
They were in the 2e monster books too.
As for 3e ... I do not remember too clearly, to be honest, which may explain the reason why you would be having trouble finding or remembering the stats....
Guys, myconids are in the MM2. Good stuff.
They're one of the reasons A4 is one of my favorite modules.
