Perichaena depressa

On decaying ground wood, with sessile, densely clustered sporocarps with sporothecae angular from mutual pressure, 0.3 to 0.8 mm across, orange-brown to dark brown with maturity, and with a yellow line of dehiscence.

Peridium double, thick, with a cartilaginous, opaque outer layer often containing refuse particles, covered with calcium crystals, and a thin, membranaceous inner layer.

Columella absent.

Capillitium abundant, pale yellow under the microscope, formed by tubules 1.5 to 2.5 µm wide, sparsely branched, not attached to the peridium, with a slightly roughened surface and very few free ends.

Spores globose to subglobose, pale yellow under the microscope, 9.5 to 11.5 µm long, 9 to 10.5 µm wide, verrucose, with fine warts uniformly distributed across their entire surface.
