The root-hairs penetrate between masses of the hyphae of the Fungus.
The hyphae of the mycelium of this fungus are septate, with numerous short branches.
The internal tissue of the body of the solid higher Fungi, particularly the elongated stalks (stipes) of the fructifications of the Agarics, consists of hyphae running in a longitudinal direction, which no doubt serve for the conduction of organic food substances, just as do the trumpet-hyphae, similar in appearance, though not in origin, of the higher Brown Seaweeds.
In many forms its hyphae are particularly thick-walled, and may strikingly resemble the epidermis of a vascular plant.
The internal tissues, either consisting of obvious hyphae or of pseudoparenchyma, may also serve as a storehouse of plastic food substances.
