A small tree or large shrub in botanical terminology, especially in fungal contexts where 'arbuscular' describes branching structures resembling small trees.
Latin word meaning 'small tree,' diminutive of 'arbor.' In mycology, it describes the tree-like branching patterns within arbuscular mycorrhizal fungi.
In the soil beneath your feet, arbuscular structures exist in mycorrhizal networks—fungi form tiny tree-shaped branches inside plant roots, creating one of nature's most important partnerships for plant nutrition!
