Study Notes
Interactions with Humans
- Fungi like mushrooms and truffles are consumed as food
- Fungi are essential in producing foods we consume such as blue cheese, bread, and soy sauce
- Fungi produce valuable drugs like penicillin
Lichen
- Lichen consists of green algae (a protist) and fungi growing together
- The relationship between algae and fungi in lichen is a mutualistic symbiotic relationship, meaning both organisms benefit
Types of Lichen
- Crustose lichen grows tightly appressed to a substrate and adheres very closely to substances at all points
- Foliose lichen has a leaf-like thallus loosely attached to the surface
- Fruticose lichen is characterized by coral-like shrubby or bushy growth structure and has a thallus and a holdfast
