Here's my easy poor man's way for mushroom and toadstools for model bases.
Grab a packet of these little things used for decorating cards and paper and stuff and grab a packet of cheap wooden toothpicks.
Cut pointy bit off the toothpick and glue to the bottom of the button. Then cut off however tall you want your fungus.
Then glue to the base. Then prime and paint then boom you got mushrooms and toadstools grown from your forest floor themed bases.
