Perichaena corticalis

On decorticated decaying wood on the ground, with sessile, globose sporocarps 0.3 to 1 mm in diameter, clustered in extensive colonies of numerous specimens, reddish brown to yellowish brown, with a yellow line of dehiscence.

Peridium double with two closely appressed layers: a thick, opaque outer layer, and a thin, hyaline, membranaceous inner layer.

Columella absent.

Capillitium sparse, elastic, pale yellow under the microscope, 1.5 to 4 µm wide, with simple or sparsely branched tubules not attached to the peridium, with an irregular, verrucose surface, few free ends, and blunt terminations.

Spores globose to subglobose, pale yellow under the microscope, 11.5 to 14 µm long, 11 to 13 µm wide, finely verrucose, with numerous fine warts uniformly distributed across the surface.
