Surface semiglossy, may be particularly dull or rough when dried bits of the mucilaginous envelope remain; otherwise, surface is reticulate-pitted, with the sinuous cell walls forming a maze of thick, rounded, undulating ridges (may also have striations or appressed hair-like or scale-like cell wall structures on top of the reticulations and interspaces), tan to yellowish-brown, margin sometimes darker.

Hilum marginal, in notch, narrowly elliptic to ovate, ± sunken especially at the larger end of the scar, lighter or darker than testa, 0.6–0.8 mm long.
