Level 2 means:
* this activity requires you to do some research
* this activity has a number of steps
* the activity uses another online tool, which is also undergoing lots of growth
* this activity needs some mushroom experts to give us some advice about what to do
I was pointed to this great website - www.mushroomobserver.org
Here's how you can get involved with locating mushrooms
Note: it would be really good to develop a Level 3 project, which involves getting involved in real local mushroom research. mushroomobserver.org has a lot of geolocated information about mushrooms, and seems like they hope to connect that with real scientific research about the mushrooms.
