ovate or elliptic to obovate, apex broadly acute to rounded or emarginate, short- to long-awned, margins narrowly recurved or revolute to near apex, commonly bordered distally with 2–4 rows of thicker-walled, papillose to smooth cells;

distal laminal cells hexagonal, 10–15 µm wide, 1:1, strongly papillose with 2(–4)-fid papillae.
