Phylum Zygomycetes
Example is bread mold. Only 665 species
Zygomycetes are partners in most ancient type of mycorrhizae.
Phylum Ascomycetes, spores in sacs, 30,000 species.
Nectria perithecia A species in this genus causes Beech Bark Disease

Review of Mycorrhizal Types
A stained arbuscule of Glomus mosseae in a leek root cell(a superb photomicrograph by Mark Brundrett - see Fig 17 in Brundrett et al. 1984 Can. J. Bot. 62: 2128)
Endomycorrhizae-- ancient, widespread, and non-specific
http://www.mycolog.com/chapter17.htm
These structures in the "roots:" of early land plants fossilized in the Rhynie Chert (350 MYBP) are regarded as vesicles of an early endomycorrhizal fungus.
Colonization of a root by an endomycorrhizal fungus. Note hyphae, arbuscules and vesicles. (see Fig 21 in Brundrett et al. 1985 Can. J. Bot 63: 184)
A leek root packed with vesicles of its endomycorrhizal fungal partner.
Ectomycorrhizae
Ectomycorrhizas of Laccaria bicolor with Populus tremuloides.
Transverse section of an ectomycorrhiza of Pseudotsuga menziesii with Rhizopogon colossus showing the fungal mantle (brown in this example).
Section of outer layers of an ectomycorrhizal root of Pinus strobus,showing some of the mantle and the Hartig net -the latter formed by hyphae of the mycobiont, Pisolithus tinctorius, penetrating between the cortical cells of the root.
