I've never been so hot and bothered after looking at mushrooms before

Yes I grow medicinal and gourmet ones. What you'er actually watching in the video is the fruiting cycle not the main growth/colonization. The part your seeing is basically the reproductive sex organ of hte mushroom with the bulk of it being fibrous, usually white, stringy material growing in the substrate (whatever it is, usually some form of compost or a host).
I see a ton of Amanita Muscaria in the video, the sons of thunder ;)
