| Mycelium | complex, netlike mass made up of branghing hyphae. |
| Fruiting body | spore-producing fungal reproductive structure |
| Septum | cross-wall that divides a hypha into cells |
| Haustorium | specialized hypha of parasitic fungi that grows into a host's tissues and absorbs its nutrients. |
| Spore | reproductive haploid (n) cell with a hard outer shell that forms a new organism without the fusion of gametes and is produced in the asexual and sexual life cycles of most fungi and some other organisms. |
| Sporangium | sac or case in which fungal spores are produced |

| Conidiophore | spore-producing hypha of sac fungi |
| Ascocarp | in sac fungi, the reproductive structure in which haploid nuclei fuse to form a zygote. |
| Ascus | spore-producing saclike structure of sac fungi |
| Ascospore | spore produced by an ascus |
| Basidiocarp | fruiting bod of basidiomycetes |
| Basidium | club-shaped, spore-producing hypha of basiomycetes |
| Basidiospore | haploid spore released b a basidium during reproduction |
| Lichen | symbiotic relationship between a fungus (usually an ascomycete) and an alga or a photosynthetic partner |
| Bioindicator | living organism that is sensitive to environmental conditions and is one of the first to respond to changes |
| Mycorrhiza | symbiotic relationship between a specialized fungus and plant roots fungal hyphae help plants obtain water and minerals and plants supply carbohydrates and amino acids to the fungus |
