They are easy to grow indoors as well -would suggest to try hardwoods (oak, poplar, beech, etc). Works best with grain spawn (not liquid inoculum)

You could try milky mushroom (Calocybe indica) if you live in an area with hot weather

Try to grow something simple like oysters first then later when you gain some experience try portobellos

Yes, they are stinkhorn mushrooms !

Yes, you can still use those plugs

IF you go for fungi, make sure you pick pine loving mushrooms (oysters will do: especially blue oyster, and phoenix)

They might fruit depending on the strain (some strains fruit some others not)

Eukalyptus is not the best substrate for growing mushrooms. Avoid growing chicken of the woods on it

Take a mycology class and you'll get proper guidance. When you score the internet for it you'll find a bunch of voices telling you what you should do. One specialist that knows how to guide you is what you need. I'm an instructor in mycology and I have online classes about how to propagate mycelium, how to make spawn and such. Let me know if you're interested
