Diderma hemisphaericum

Peridium double, with a very fragile outer layer formed of white lime granules and a partially evanescent membranous inner layer underneath, persisting only at the base of the sporotheca.

Capillitium formed by very slender, hyaline, abundantly branched threads, sparingly anastomosed.

Spores globose, very pale brown under the microscope, verrucose, with clusters of darker warts.
