716546651yeastsSingle-celled fungus. Reproduce asexually by binary fission or by the pinching of small buds off a parent cell.
716546652hyphaeOne of many connected filaments that collectively make up the mycelium of a fungus.
716546653chitinA structural polysaccharide, consisting of amino sugar monomers, found in many fungal walls and in the exoskeletons of all arthropods.
716546654myceliumThe densely branched network of hyphae in a fungus.
716546655septaOne of the cross -walls that divide fungal hypha into cells. Generally have pores large enough to allow ribosomes, mitochondria, and even nuclei to flow from cell to cell.
716546656coenocytic fungiA fungus that lacks septa and hence whose body is made up of a continuous cytoplasmic mass that may contain hundreds or thousands of nuclei.
716546657haustoriaIn certain symbiotic fungi, a specialized hypha that can penetrate the tissues of host organisms.
716546658mycorrhizaeA mutualistic association of plant roots and fungus.
716546659Ectomycorrhizal fungiAssociation of a fungus with a plant root system in which the fungus surrounds the roots but does not cause invagination of the host (plant) cells' plasma membranes.
716546660Arbuscular mycorrhizal fungiA symbiotic fungus whose hyphae grow through the cell wall of plant roots and extend into the root cell (enclosed in tubes formed by invagination of the root cell plasma membrane).
716546661sporesA haploid cell, produced either sexually or asexually, that produces mycelium after germination.
717204196pheromonesIn animals and fungi, a small molecule released into the environment that functions in communication between members of the same species.
717204197plasmogamyIn fungi, the fusion of cytoplasm of cell from two individuals; occurs as one stage of sexual reproduction, followed later by karyogamy
717204198heterokaryonA fungal mycellium that contains two or more haploid nuclei per cell.
717204199dikaryoticReferring to a fungal mycelium with two haploid nuclei per cell, one from each parent.
717204200karyogamyIn fungi, the fusion of haploid nuclei contributed by the two parents; occurs as one stage of sexual reproduction, preceded by plasmogamy.
717204201moldsInformal term for a fungus that grows as a filamentous fungus, producing haploid spores by mitosis and forming a visible mycelium.
717204202deuteromycetesTraditional classification for a fungus with no known sexual stage.
717204203opisthokontsMember of the diverse clade of Opisthokonta, organisms that descended from an ancestor with a posterior flagellum, including fungi, animals, and certain protists.
717204204nucleariidsMember of a group of unicellular, amoeboid protists that are more closely related to fungi than they are to other protist.
717204205chytridsMember of the fungal phylum Chytridiomycota, mostly aquatic fungi with flagellated zoospores that represent an early diverging fungal lineage
717204206zoosporesFlagellated spore found in chytrid fungi and some protists.
717204207zygomycetesMember of the fungal phylum Zygomycota, characterized by the formation of a sturdy structure called a zygosporangium during sexual reproduction
717204208zygosporangiumIn zygomycete fungi, a sturdy multinucleate structure in which karyogamy and meiosis to occur.
717204209glomeromycetesMember of the fungal phylum Glomeromycota, characterized by a distinct branching form of mycorrhizae called arbuscular mycorrhizae.
717204210AscomycetesMember of the fungal phylum Ascomycota, commonly called sac fungus. The name comes from the saclike structure in which the spores develop.
717204211asciA sacklike spore capsule loacated at the tip of a dikaryotic hypha of a sac fungus.
717204212ascocarpsThe fruiting body of a sac fungus (ascomycete)
717204213conidiaA haploid spore produced at the tip of a specialized hypha in ascomycetes during sexual reproduction.
717204214basidiomycetesMember of the fungal phylum Basidomycota, commonly called club fungus. The name comes from the club-like shape of the basidium.
717204215basidiumA reproductive appendage that produces sexual sores on the gills of mushrooms (club fungi)
717204216basidiocarpsElaborate fruiting body of a dikaryotic mycelium of a club fungus
717204217endophytesA fungus that lives inside a leaf or other plant without causing harm to the plant.
717204218lichenThe mutualistic association between a fungus and a photosynthetic alga or cynaobacterium.
717204219sorediaIn lichens, a small cluster of fungal hyphae with embedded algae.
717204220mycosisGeneral term for a fungal infection.
