Oligonema affine

On wet decaying wood on the ground, formerly known as Trichia affinis, with sessile sporocarps crowded in large groups, without a stipe, attached directly to the substrate by the base, with subglobose sporothecae, 0.5 to 1 mm in diameter, yellow, with a simple membranaceous peridium, partially evanescent, remaining only at the base, with irregular dehiscence.

Capillitium orange-yellow under the microscope, with elaters 5 to 6 µm wide, ornamented with 3 to 5 smooth spiral bands, and with numerous short pointed free ends 5 to 10 µm long.

Spores globose, pale yellow under the microscope, 11 to 13.5 µm in diameter, ornamented with coarse ridges that merge to form a fragmented wide-meshed reticulum.
