Answer:
The correct answer is option A. Club fungi.
Explanation:
Mushrooms and shelf fungi are the member of basidiomycetes also known as club fungi or true fungi. The cells of basidiomycetes called basidia bear sexual spores that look like a small club.
These fungi are often called club fungi because of their resemblance to the basidium to the club. Their club shape distinguishes their group to other fungi.
Some examples of club fungi or basidiomycetes are rusts, smuts, puffballs, and shiitake mushrooms.
So, the correct answer is option A. Club fungi.
