Liaison

One of Mužmir's fruiting body variations. Alongside his humanoid variant (Settlers), there are also variants built for other purposes such as Liaison- (designed for interfacing with machinery, an extrapolation of pre-existing tech where they can plug mushrooms into modular synths and robot arms) and Origin types (mycelial networks, acts most like the normal fungus, grows more fruiting bodies with the information provided by the parent body (usually a Settler, since the other two are stationary)).
All of them are equally Muž with his personality and motivations. They are just doing their part in a collective system - not exactly a hivemind but it can get pretty close to it when they're all kept on the same page.
