Introduction

Basidiomycota: The Club Fungi

Antheridium  -  A male reproductive organ found in ascomycota.
Ascogonium  -  The female reproductive organ of ascomycota
Ascogonius hypha  -  A dikaryotic hypha that grows out of a fertilized ascogonium.
Ascus  -  The reproductive structure of ascomycota in which fusion, meiosis, and spore formation take place.
Basidioma  -  The fruiting body of basidiomycota in which basidia form.
Basidium  -  The club-shaped reproductive structure of basidiomycota in which fusion, meiosis, and spore formation take place.
Binucleate  -  Having two nuclei.
Budding  -  Asexual reproductive process in which a small portion of the cell membrane and cytoplasm receive a nucleus and pinch off from the parent cell.
Cellulose  -  A major component of plant and algal cell walls. Compare with chitin.
Chitin  -  A major component of fungal cell walls that is not found in the cell walls of any other group. Compare with cellulose.
Clamp connection  -  The structure by which basidiomycota cells divide while retaining their binucleate dikaryotic condition.
Conidiophore  -  Structure in which asexually-produced spores called conidia are formed.
Dikaryotic  -  Having two distinct sets of genetic information.
Gametangia  -  In zygomycota, the cells which fuse to become the zygote.
Fruiting body  -  A general term for elaborate structures that contain spore-forming cells.
Hypha  -  Individual filaments of fungal cells; compare with mycelium.
Karyogamy  -  The fusion of two nuclei.
Mycelium  -  The usually underground portion of a fungus that is haploid and sprouts from a spore.
Plasmogamy  -  Fusion of the plasma membranes of two cells.
Rhizoid  -  The sub-surface hyphae of zygomycota specialized for food absorption
Sporangiophores  -  Filamentous stalk on which a sporangium forms.
Sporangium  -  Spore producing structure of zygomycota.
Stolon  -  The hyphae that connect groups of rhizoids and sporangiophores, usually above the surface.
Symbiont  -  An organism that lives in close association with another, to the benefit of one or both organisms.
Trichogyne  -  Specialized cell on the end of the ascogonium. During mating, the trichogyne grows to connect the ascogonium to the antheridium.
Zygospore  -  The heavily encasulated structure that forms from the zygote of zygomycota
Zygote  -  The diploid cell that results from the fusion of two gametes or gametangia during fertilization.
