Glossary of Mycological Terms
- An asexual state of a fungus.
- A fruiting body containing asci and ascospores.
- A group of fungi that reproduce sexually by the endogenous formation of ascospores in an ascus.
- A haploid spore produced within an ascus following karyogamy and meiosis.

- Basidium (pl. basidia)
- A cell that gives rise to a basidiospore. Basidia are characteristic of the Basidiomycetes.
- A chain of conidia, the oldest conidium is at the apex and the youngest is at the base.
- Conidia arranged in chains.
- Clamp connection
- A specialized hyphal bridge over a septum in the Basidiomycetes.
- Cleistothecium (pl. cleistothecia)

- Cylindric, having parallel walls and circular cross-section.
- A dark brown, greenish gray or black colour.
- A small projection or peg on which conidia are produced.
- A type of hyphal branching into two equal forks.
- Dictyoconidium (pl. dictyoconidia)
- A conidium with both longitudinal and transverse septa; a muriform conidium.
- Didmoconidium (pl. didymoconidia)
- A two celled conidium.
- Having two different morphological forms.
- Dolipore septum
- A characteristic septum found in the Basidiomycetes that flares out near the pore to form an elongate channel.
- Double septum
- A two layered septum that may undergo centripetal separation (schizolysis) to release a conidium.
- Covered with delicate spines.
- Spread out, radiate.
- Oval, with a symmetric curve.
- A spore produced within a spherule.
- Droplets of fluid formed on the surface of a colony.
- Curved like a sickle.
- Fluffy or cottony.
- Spindle-shaped, tapering toward the end.
Bent like a knee.
- Conidia aggregated in slimy heads at the tip of an annellide or phialide.
- Containing one or more oil droplets.
- Gymnothecium (pl. gymnothecia)
- A non-ostiolate ascocarp composed of loosely interwoven hyphae and containing randomly dispersed asci.
- A prefix meaning hyaline to lightly colored.
- Hypha (pl. hyphae)
- A single filament of a fungus.
- A class of mycelial moulds which reproduce asexually by conidia on hyphae or aggregations of hyphae.
- On the side.
- Shaped like a double convex lens.
Sticky or slimy.
Having several septa.
- A conidium with both longitudinal and transverse septa.
- Mycelium (pl. mycelia)
- The mass of hyphae making up the thallus of a fungus.
- Without septa.
- Club-shaped in reverse; the distal region is smaller.
- Pear-shaped in reverse; the distal region is larger.
- Olive-grey color.
- An opening or pore in an ascocarp or a pycnidium.
- Like the teeth of a comb.
- A slender stalk.
- The outer wall of an ascocarp.
- Perithecium (pl. perithecia)
- An enclosed ascocarp characterized an apical ostiole and by asci arranged in a basal tuft or hymenium layer.
- A prefix meaning darkly pigmented.
- Having more than one form.
- Poroconidium (pl. poroconidia)
- A conidium produced through a small pore in a conidiogenous cell.
- Covered with whitish dust or bloom
- A string of elongated blastoconidia formed in some yeasts that resemble a hypha-like filament.
- Pycnidium (pl. pycnidia)
- An asexual fruiting body containing conidia.
- A short branching root-like hyphae seen in some Zygomycetes.
- Sclerotium (sclerotia)
- A mass of thick-walled cells formed by the vegetative hyphae that function as an organ of perennation.
- Septum (pl. septa)
- A cross wall in a hypha.
- Covered in small spines.
- Sporangiolum (pl. )
- A small sporangium producing a small number of sporangiospores.
- A specialized hypha that bears a sporangium.
- Sporangium (pl. sporangia)
- A sac-like structure producing asexual spores endogenously by cytoplasmic cleavage.
- A reproductive propagule formed by either meiosis or mitosis. However, if by asexual means, cleavage of cytoplasm is usually involved.
- Sporodochium (pl. sporodochia)
- A cushion-shaped mass of hyphae bearing conidiophores.
- Sterigma (pl. sterigmata)
- A small pointed structure upon which a basidiospore forms.
- A running hypha from which rhizoids and sporangiospores arise.
