Glossary

Term Description
Ascocarp The fruiting body of an ascomycete fungus, which contains the sexual reproductive structures.
Ascospores The sexual spores produced by fungi belonging to the phylum Ascomycota.
Ascus Sac-like structure of ascomycete fungi, in which sexually produced spores, called ascospores, are formed.
Cystidia Specialized, often thick-walled, hyphal structures that occur on the surface of the fungal mantle. They are typically differentiated from ordinary hyphae by their shape and function.
ECM Abbreviation for ectomycorrhiza.
Ectomycorrhiza A type of mycorrhiza in which the fungus forms a sheath around the root and its hyphae penetrate between root cells, creating a Hartig net.
Epidermoid cells Cells located in the outer layer of the mycorrhizal mantle, resembling plant epidermal cells.
Fertile veins Darker regions of the gleba that contain the hymenium, where asci and spores are produced.
Gleba The internal tissue of the ascocarp, where asci and spores develop. It often exhibits a marbled pattern due to sterile veins.
Hartig net A network of fungal hyphae that penetrates between the epidermal and cortical cells of the host plant root in ectomycorrhizal associations, facilitating nutrient exchange between the fungus and the plant.
Hymenium Part of the ascocarp that contains reproductive structures (Asci and Spores).
Mantle Synonym of mycoclena.
Mycoclena A dense layer of fungal hyphae surrounding the root tips of the host plant.
Mycorrhiza A symbiotic structure formed between the roots of a host plant and mycorrhizal fungi, facilitating nutrient exchange.
Peridium The outer layer of the ascocarp, often textured or ornamented.
Sterile veins Whitish veins within the gleba that create the characteristic marbled appearance of the ascocarp. These veins usually are connected to the external of the ascocarp.
Truffle The ascocarp formed by Tuber species.
Warts Melanized, pyramidal structures on the outer surface of the peridium, characteristic of black truffles.
