The Mushroom People were and are those found living off the land of the Mushroom Planes usually found on islands. Mushroom Foragers were those who foraged for mushrooms around the island when the mushroom farms were running low or to find exotic fungi. They were more meager in their attire and were usually poorer but were respected by the other inhabitants of their village. Why they were poor: I do not know, but it may be that they took on a friar-like lifestyle in mushroom gathering. They shared similar jobs to the Mushroom Hunters but did not extend past mushroom foraging. When foragers grew old, they would pass on the secrets of locating growing places for mushrooms down to both younger hunters and foragers.
