What topic could you give a 20-minute presentation on without any preparation?

@caccoon Mushrooms? I'd be interested to hear about that, I always see them in the woods and wonder about them...

@fun4us2b Mushrooms are amazing. I used to walk around with two mushroom identification books when I was a kid haha. And hunt wild mushrooms.

@caccoon The only thing I know (but not sure) is that if they are growing on wood, they are safe to eat. If on the ground, they might not be...

@fun4us2b Oh, interesting! I had actually never heard that before! I do remember one that grew on trees growing up that was quite poisonous, though!

@caccoon You are right! This is an interesting topic...from a little googling: "Mushrooms with white gills are often poisonous. So are those with a ring around the stem and those with a volva. Because the volva is often underground, it's important to dig around the base of a mushroom to look for it. Mushrooms with a red color on the cap or stem are also either poisonous or strongly hallucinogenic."

@caccoon very interesting 👍️
