Peridium simple, yellowish-brown under the microscope, partially evanescent, persisting basally as a small calyculus and the rest forming a peridial net of slender threads with thickened nodes, without free ends, with abundant calcium granules up to 1.5 µm concentrated in the calyculus and net nodes.

Columella and capillitium absent.

Spores pale yellow under the microscope, globose, with faint, moderately coarse warts across the entire surface.
