Thems the breaks when you're raised in myco-phobic cultures.
Fungus are closer to us than plants, genetically.
Science knows next to nothing about the extents of fungal connections & interactions (compared to acquired knowledge of plant & animal biology).
Agriculture is wallowing in the dark ages, denying myco-culture wherever possible.
Things are starting to turn around. Some colleges and universities actually have mycology departments now, though many current mycologists had to declare their major as 'biology' to arrive there.
