Medullary filaments 10-25 µm diam., tightly intertwined near surface, loosely intertwined at center, extending into cortex (i.e., overlapping and intertwined with bulbous cortical cells). Cortex indistinct. Surface filaments cylindrical, 15-26 µm diam., to 1-4 mm long, lightly pigmented, arising from center loosely intertwined medullary filaments; cells 2-3 diameters long.
