Stemonitis flavogenita

E.Jahn, 1904

Microscopía de Stemonitis flavogenita

Study description

On moist decaying wood or bark on the ground, with stalked sporocarps fruiting in cespitose clusters, 4 to 9 mm in total height, with cylindrical brown sporothecae and a short black stipe up to only 1/4 of total sporocarp height.

Columella dark brown, reaching the apex of the sporotheca, with a characteristic membranous cup-shaped apical expansion.

Capillitium formed by fairly slender brown filaments, with a surface net of small meshes 7 to 18.5 µm long and 6 to 14 µm wide, with small spinose free ends.

Spores globose, purplish-brown under the microscope, 7.5 to 9 µm in diameter, ornamented with scattered, evenly distributed warts, not forming ridges or a reticulum.
