Vesicular Arbuscular Mycorrhizae (VAM)

The endotrophic mycorrhiza formed of aseptate fungi are popularly known as Vesicular Arbuscular Mycorrhizae (VAM). This named so because in several cases, the hyphae of the fungus are dichotomously and produce vesicles called haustoria. This vesicles are present within the host cells called arbuscules. These kind of mycorrhiza are very common in bryophytes, pteridophytes, gymnosperms like Junipterus Sequoia and in several angiosperms. The usual fungi that enter these kinds of mycorrhizae are Endogone, Sclerocystis, Glomus, etc
