Mycorrhizae

Mutualistic associations of fungi and plant roots that aid in the plant’s absorption of essential minerals from the soil. Hyphae of ectomycorrhizal fungi coat plant roots; those of endomycorrhizal fungi penetrate plant cell walls (see arbuscules).

Ascospores

Sexual spores produced within the ascus of ascomycete fungi during the sexual phase of their life cycle.

Zygospores

Thick-walled resting spores formed by the union of two morphologically similar or dissimilar haploid cells, commonly found in fungi and some protists.

Ascospores

Spores produced by ascus, a type of fungal hyphae, during the sexual reproduction phase of ascomycetes.
