Starwine Mushrooms
This is the standalone version.

A swiftly regrowing patch of star shaped mushrooms(they count as 'manky') that you never have to worry about going extinct or taking over the metaroom.  The mother plant(counts as a weed) in the center of the patch will reseed the mushroom patch as it is eaten and the mushrooms will only grow next to the mother.
This agent was made to provide an extra food source for toxic creatures, creatures that love manky, and to provide a source of tryptamine & hallucinogen for the CFF & Abyss Dragon based breeds.  If you shift + ctrl click on a starwine mushroom mother, the mother will be removed and the grove will no longer respawn after being eaten.
