The type of mycorrhiza formed depends on the level of auxin secretion by the fungus and on the sensitivity of the plant root to auxin, whether. Perhaps more than 80% of the species of higher plants have these relationships, and so do Below, we consider three of the commonest types of mycorrhiza. There are more than species of mycorrhizal fungi found around the world in all types of soils and climates. There are several general classes to categorize.

David Moore's World of Fungi: where mycology starts

Description of Types, Benefits and Uses By Troy Buechel and Types of mycorrhiza Bloodnick Incorporate these beneficial organisms into your production, and you may see improved plant growth and types of mycorrhiza nutritional deficiencies, as well as benefits to the end user.

Over the past several decades, a strong interest has developed in the identification and culture of beneficial soil organisms.


It is documented that many bacteria and fungi can help plants in combating diseases, locate nutrients and acquire water when in short supply.

Within the beneficial organisms exists a complex group of fungi called mycorrhizae Figure 3, page Most mineral soils contain types of mycorrhiza fungi, but types of mycorrhiza at levels that are too low for adequate colonization, especially in disturbed soils tilled fields, gardens, landscapes, new housing, etc.

Mycorrhizae are host specific and will only colonize certain plants; so in some soils, there are no native mycorrhizae that will benefit these plants.

Therefore, most plants would benefit from mycorrhizae addition to the soil. Magnification detail of root cell containing an arbuscule little tree endomycorrhizal structure.

Mycorrhiza: Meaning, Types and Role

Magnification of vesicles round balloon-like structures found between plant root cells. These organic components along with the growing medium they compose do not have mycorrhizal fungi strains types of mycorrhiza would benefit the crops grown in them, so they must be incorporated.


There is no fungus mantle, but only a loose and very sparse network of septate hyphae spread into the soil. Types of mycorrhiza hyphae bear different types of spores, chlamydospores, or aggregation of spores in sporocarp or zygospores.

Mycorrhizal types

Intercellular hyphae form arbuscles types of mycorrhiza the parenchyma of cortex by repeated dichotomous branching of the penetrating hyphae.

The cell membrane of the penetrated cell is invaginated and covers the arbuscles.

The hyphae also develop both inter- and intracellular thick-walled vesicles. The chlamydospores may germinate on nutrient agar, but the hyphae stop growing when types of mycorrhiza inside the spore is used up, thus they cannot be subcultured. This type of association was types of mycorrhiza very early in the evolution land plants.

This is actually a type of endomycorrhiza.

Ericoid mycorrhizae are found in the different members of Ericaceae like Erica, Calluna, Vaccinum, Rhododendron etc. The fungi are slow-growing, septate and mostly sterile. They are mostly culturable.

Ectomycorrhizas Ectomycorrhizas sometimes termed ectotrophic mycorrhizas are characteristic of many trees in the cooler parts of the world - for example pines, spruces, types of mycorrhiza, oaks, birches in the Northern Hemisphere and eucalypts in Australia.


However, some trees e. The fungi involved are mainly Ascomycota and Basidiomycotaincluding many that produce the characteristic toadstools of the forest floor Figures A-C types of mycorrhiza.

Most of these fungi can be grown in laboratory culture but, unlike the wood-rotting fungi, they are poor degraders of cellulose and other plant wall materials.
