- arbuscular mycorrhiza

- arbuscular mycorrhiza - mycorrhizal association in which the fungal hyphae enter the root cells and form extensive networks - Arbuscular mycorrhizae - mycorrhizae commonly involving Glomeromycetes in which the fungal hyphae penetrate the cell walls of the plant root cells (but not the cell membranes) - ascocarp - fruiting body of ascomycetes - Ascomycota - (also, sac fungi) phylum of fungi that store spores in a sac called ascus - basidiocarp - fruiting body that protrudes from the ground and bears the basidia - Basidiomycota - (also, club fungi) phylum of fungi that produce club-shaped structures (basidia) that contain spores - basidium - club-shaped fruiting body of basidiomycetes - Chytridiomycota - (also, chytrids) primitive phylum of fungi that live in water and produce gametes with flagella - coenocytic hypha - single hypha that lacks septa and contains many nuclei - commensalism - symbiotic relationship in which one member benefits while the other member is not affected - Deuteromycota - former form phylum of fungi that do not have a known sexual reproductive cycle (presently members of two phyla: Ascomycota and Basidiomycota) - ectomycorrhiza - mycorrhizal fungi that surround the roots with a mantle and have a Hartig net that extends into the roots between cells - Ectomycorrhizae - mycorrhizae in which the fungal hyphae do not penetrate the root cells of the plant - facultative anaerobes - organisms that can perform both aerobic and anaerobic respiration and can survive in oxygen-rich and oxygen-poor environment - Glomeromycota - phylum of fungi that form symbiotic relationships with the roots of trees - haustoria - modified hyphae on many parasitic fungi that penetrate the tissues of their hosts, release digestive enzymes, and/or absorb nutrients from the host - heterothallic - describes when only one mating type is present in an individual mycelium - homothallic - describes when both mating types are present in mycelium - hypha - fungal filament composed of one or more cells - karyogamy - fusion of nuclei - lichen - close association of a fungus with a photosynthetic alga or bacterium that benefits both partners - mold - tangle of visible mycelia with a fuzzy appearance - mycelium - mass of fungal hyphae - mycetismus - ingestion of toxins in poisonous mushrooms - mycology - scientific study of fungi - mycorrhiza - mutualistic association between fungi and vascular plant roots - mycorrhizae - a mutualistic relationship between a plant and a fungus. Mycorrhizae are connections between fungal hyphae, which provide soil minerals to the plant, and plant roots, which provide carbohydrates to the fungus - mycosis - fungal infection - mycotoxicosis - poisoning by a fungal toxin released in food - obligate aerobes - organisms, such as humans, that must perform aerobic respiration to survive - obligate anaerobes - organisms that only perform anaerobic respiration and often cannot survive in the presence of oxygen - parasitism - symbiotic relati
