| Mycorrhizal systems fairly long with frequent, irregularly spaced, short branches; mycorrhizal ends with fringes of short differentiated hyphae, ends of two disrinctive forms, one, a pale form, is white when young, turning to fawn to darker shades of orange or grey-brown with age, the second form is silver-dark brick when young, turning to purplish chesnut with age. | |
