Hemitrichia calyculata

Sporocarps slightly over 2 mm tall, with a differentiated cylindrical dark brown stalk and a pyriform sporotheca.

Peridium membranous, simple, delicate, irregularly dehiscent apically, persisting only at the base as a calyculus (cup-shaped).

Capillitium golden-ochre under the microscope, 5-7 µm wide, branched, tangled, with 4-5 spiral bands, with minute, nearly imperceptible spines on its surface, very few free ends, these terminal elements with rounded apices.

Spores very pale yellow under the microscope, globose, moderately thick-walled, ornamented with delicate spinules forming a small incomplete reticulate mesh.
