I don't know if this word really has a use, because there is mycologist, which etymologically is more appropriate for "who studies fungi". Still, this Greco-Latin pastiche is not an absurdity either, since the Latin fungus, i means "mushroom" and the Greek 955; 959; 947; 959; 962; (logos) indicates a "relationship or theme".
* Only one "like" per meaning and day, the more "likes" the meaning will appear higher in the list
