Our intracellular structure and the way we obtain energy.
There are many differences and many similarities between fungi and humans. In basic biology, however, we can state two major facts that the both have in common when compared to other groups of living beings. The fisrt one is our intracellular structure: fungi and humans present eukaryotic cells (such as plants and protozoa), which, unlike bacteria, have a membrane protecting its nuclei. Another difference is the way we obtain our energy: both humans and fungi are heterotrophic (unlike plants, algae and some bacteria and protozoa). This means we generate energy by consuming elements in the ecossystems, or simply by feeding on other organisms, instead of producing our own food like plants do.
