well hilariously botany is what you want to start into. which mainly concerns plant sciences, but for some reason they lump fungi into botanical studies.
fungi are actually more related to animals than plants, and if we wanted it to be accurate then they would research them in zoology.
but go into botany to begin with, or if your school has a mycology undergrad then do that. but usually mycology is something for a masters or phd.

Thanks!

A nigger is a black, plain and simple. You can take the term to be offensive or not, but a black is always a nigger.
Same way that a Jew is a kike, or a Chinese is a chink, a gay is a faggot, or what else have you. They're derogatory terms to describe those giant groups of people, not the lowest common denominator of those people.
