Fungi on the tree of life:
Fungi are eukaryotic organisms which can parasitize humans. Fungi can grow in two different ways: as single-celled yeasts or as branched, multicellular mycelia. Fungi are not always parasites; many types of fungi are important foods or medicines for humans. There are also many types of fungi that survive harmlessly on humans. Fungi either reproduce asexually by fragmentation, budding, or spore production, or reproduce sexually using mycelia. Below are four examples of fungi which commonly infect humans.
