resulting in fungal hyphae growth towards compatible plant roots. The EcM forms an extensive hyphal sheath, or mantle, around the root cap and a hartig net of hyphae that extends into the root ...

They first employed physics-based models of inflationary tip growth to determine all "possible" shapes of hyphae.

It can grow in a variety of morphogenic forms ranging from unicellular yeast, chains of elongated cells known as pseudohyphae and finally true hyphae consisting of long tubes with parallel sides.
