one of the many connected filaments that collectively make up the mycelium of a fungus.
A structural polysaccharide, consisting of amino sugar monomers, found in many fungal cell walls and in the exoskeletons of all arthropods.
the densely branched network of hyphae in a fungus.
one of the cross-walls that divide a fungal hypha into cells. These generally have pores large enough to allow ribosomes, mitochondria, and even nuclei to flow from cell to cell.
A fungus that lacks septa and hence whose body cavity is made up of a continuous cytoplasmic mass that may contain hundreds or thousands of nuclei.
In certain symbiotic fungi, a specialized hypha that can penetrate the tissues of host organisms.
A mutualistic association of plant roots and fungus.
A symbiotic fungus that forms sheaths of of hyphae over the surface of plant roots and also grows into extracellular spaces of the roots cortex.
Arbuscular mycorrhizal fungus
A 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).
In animals and fungi, a small molecule released into the environment that functions in communication between members of the same species. In animals, it acts much like a hormone in influencing physiology and behavior.
The fusion of the cytoplasm of cells from two individuals; occurs as one stage of syngamy (fertilization).
A fungal mycelium that contains two or more haploid nuclei per cell.
Referring to a fungal mycelium with two haploid nuclei per cell, one from each parent.
The fusion of two nuclei, as part of syngamy (fertilization).
The informal term for a fungus that grows as a filamentous fungus, producing haploid spores by mitosis and forming a visible mycelium.
Traditional classification for a fungus with no known sexual stage. When a sexual stage for a so-called deuteromycete is discovered, the species is assigned to a phylum.
member of the diverse clade of organisms that descended from an ancestor with a posterior flagellum, including fungi, animals, and certain protists.
member of a group of unicellular, amoeboid protists that are more closely related to fungi than they are to other protists.
member of a fungal phylum that is mostly aquatic fungi with flagellated zoospores that represent an early-diverging fungal lineage.
member of a fungal phylum that is characterized by the formation of a sturdy structure called a zygosporangium during sexual reproduction.
in zygomycete fungi, a sturdy multinucleate structure in which karyogamy and meiosis occur.
member of a fungal phylum, that is characterized by a distinct branching form of mycorrhizae (mutualistic plant relationships with plant roots) called arbuscular mycorrhizae.
member of a fungal phylum, that is commonly called sac fungus. the name comes from a saclike structure in which the spores develop.
a saclike spore capsule located at the tip of a dikaryotic hypha of a sac fungus.
the more common name for an ascomycete.
the fruiting body of a sac fungus (ascomycete)
a haploid spore produced at the tip of a specialized hypha in ascomycetes during sexual reproduction.
member of a fungal phylum commonly called club fungus. the name comes from the club-like shape of the basidium.
a reproductive appendage that produces sexual spores on the gills of mushrooms (club fungi).
the common name for a basidiomycete.
elaborate fruiting body of a dikaryotic mycelium of a club fungus.
a fungus that lives inside a leaf or other plant part without causing harm to the plant.
the symbiotic collective formed by the mutualistic association between a fungus and a photosynthetic alga or cyanobacterium.
in linchens, a small cluster of fungal hyphae with embedded algae.
general term for a fungal infection.
