Structure uniaxial, with a prominent dome or wedge-shaped apical cell; in section with a medulla of longitudinal filaments and cortex of 3 or 4 layers of progressively smaller pigmented cells. Inner layer cells 10–15 µm diam. Outer cortical cells in surface view mostly isodiametric, 5–12 µm diam., in section cuboidal or slightly broader than long. Rhizines in the medulla, often in bundles, c. 5 µm diam. Reproductive structures not observed.
