Study description

This study corresponds to Stemonitis pallida var. rubescens, according to Index Fungorum currently Symphytocarpus rubescens, an epithet not recognized by GBIF, on decaying dead wood on the ground with stipitate sporocarps, 6 to 9 mm in total height, with reddish-brown cylindrical sporothecae, 4 to 5.5 mm in length, and with a long, shiny, black stalk (stipe) occupying up to half of the total height of the sporocarp.

Dark brown to black columella merging with the capillitium near the apex of the sporotheca.

Capillitium arising along the columella, light brown to dark reddish-brown, forming an internal network of 3 to 4 meshes per radius and a surface network of smaller and finer meshes, with abundant pointed free ends resembling spines.

Spores globose, greyish-brown under the microscope, with slightly thick and minutely verrucose walls, 7 to 8 µm in diameter, and with their entire surface completely covered with fine warts.
