These miniatures are Myconids from the Dungeons and Dragons universe. Created originally for my own campaign and they can be found in the „Monster Manual“ book.

Myconids are peaceful fungi creatures living underground. There are 3 kinds, the sovereign who is the leader of a small group, the adult who is a fully grown myconid and the sprout which is still growing. Their spores also have the ability to bring dead creatures back to life as a spore servant.
