Chitin

The compound that makes up the cell walls of fungi.

Hyphae

Long filaments that make up the body of fungi.

Mycelium

A mass of hyphae that forms the body of a fungus.

Zygomycota

A phylum of fungi that includes bread molds, characterized by the formation of zygosporangium.

Ascomycota

A phylum of fungi known as sac fungi, where meiospores are made in a sac-like structure called the ascus.

Basidiomycota

A phylum of fungi known as club fungi, where meiospores are made on a club-like structure called the basidium.

Coenocytic Hyphae

Hyphae that do not have cross-walls, allowing for a continuous cytoplasm.

Septate Hyphae

Hyphae that contain cross-walls that separate individual cells.

Zygosporangium

A resistant microscopic structure in zygomycetes where meiospores are formed.

Ascospores

Meiospores produced in the ascus of sac fungi.

Conidia

Asexual spores formed by the pinching off of cells at the tips of hyphae.

Mycorrhizae

Mutualistic associations between fungi and plant roots that improve nutrient uptake.

Lichens

Symbiotic relationships between fungi and photosynthetic organisms, such as algae or cyanobacteria.

Deuteromycetes

A group of fungi that reproduce only asexually and have no known sexual reproduction.

Amanita

A genus of mushrooms known to contain poisonous species, such as the death cap fungus.

Dikaryotic Hyphae

Hyphae that contain two genetically distinct nuclei.

Fairy Ring

A natural phenomenon of mushroom growth where fungi grow in a circular pattern.

Glomeromycota

A phylum of fungi that form arbuscular mycorrhizae and are important symbionts to terrestrial plants.

Soredia

Reproductive particles in lichens that help in dispersal.

Karyogamy

The fusion of nuclei from two different mating types.

Asexual Reproduction

Reproduction that involves only one parent and produces genetically identical offspring.
