Anthracoidea eleocharidis Kukkonen, 1964
the contents of the ultimately rupturing utriculi is transformed into a globular hard, black body, 2-3 mm in size, consisting of agglutinated spores; initially it is covered by a silvery membrane, that later flakes off. The spores are 11-20 µm long, their wall is even in thickness, and papillate.
Cyperaceae, narrowly monophagous
The fungus is unknown in Europe, but it is to be expected on this sedge.
