- Sort of. Things like bread mold and yeast are somewhat more robust than the
- psilocybe mycellium & will take over the culture if left alone (non-sterile).

- While you get psilocybes growing on non-sterile horse-shit in nature, the
- conditions for growth of the mycellium must fall in a rather specific
- range of temperature, Ph, chemical composition & etc. Also, as stated above,
- the mycellium must spread through the culture (shit) before some other organism
- comes to dominate this growth medium. It would be rather
- difficult to grow mushrooms from scratch on horseshit (though it is done); it
- is much easier to have a nice source of mycellium (grown on sterile grain)
- to mix with the horse-doo that will rapidly spread through the medium (before
- other microbes make it impossible for psilocybe mycellium to grow there).

- I think this is a minor worry compared to having your growth medium overwhelmed
- by smelly bacteria & yeast.
