Lichen
A mix between algae and fungi
Saprophyte
Any organism that lives on dead organic matter, as certain fungi
Symbiosis
A close relationship between two species in which at least one species benefits from the other
Mycelium
The mass of hyphae that from the vegetative part of the fungus
Hyphae
One of the threadlike elements of the mycelium
Mycorrhiza
Symbiotic relationship between a fungus and the roots of a green plant
Chitin
Complex carbohydrate found in the arthropod exoskeletons and fungal cell walls
Myxomycete
Phylum containing a cellular slime mold
Pileus
The cap or horizontal portion of a mushroom
Spore
One cell reproductive unit capable of giving rise to new without sexual fusion
Rhizoid
One if the rootlike filaments by which the plant is attached to the substratum
Rhizopus
A genus of common saprobic fungi on plants and specialized parasites on animals
Dermatophyte
Any fungus parasitic on the skin and causing a skin disease
Annulus
The veil remnant on a mushroom stalk
Stipe
The support structure of the pileus of the mushroom
Decomposer
An organism that breaks down the cells of dead plants and animals into simpler substances
