The hyphae are arranged into a network called a mycelium.
In addition to penetrating the tree roots, the hyphae also interpenetrate each other — mycorrhizal fungi on the whole don't have divisions between their cells.
Mycelium is considered a polymer because of the hyphae, which repeat in the mycelium's structure just as styrene molecules repeat in polystyrene.
"Soil is fantastically difficult stuff to work with experimentally, and the hyphae are on the whole too thin to see," he said.
The arrow marks the hyphae in the leaf tissue.
Weindling (1932) observed Trichoderma lignorum parasitizing the hyphae of Rhizoctonia solani.
Hyphal swelling at the leading edge was also visible when the hyphae extended transversally (Fig. 2H).
It was observed that after incubation of 96 h, the hyphae were cylindrical, septate, and branched.
The hyphae, and pelotons could be found in the cells of the cortex.
A sample was filtered through a 0.45-μm millipore cellulose filter that retained the hyphae.
The hyphae have clamp connections.
