Been studying plant-fungal interactions for about 10 years, including a master's degree I dropped out of and never actually finished* so I'm full of fungus facts i don't really get to use ever.
*Actually did all the course work and lab work but didn't finish my thesis in time
*that I wasn't motivated to finish because I'm really not interested in the whole academic life and the years of essentially slave labor that's expected before you can even dream of having your own lab... And then if you do get your own lab you have to spend most of your time getting funding and not with your hands in the dirt.
