Anthracoidea intercedens Nannfeldt, 1979
the contents of the ultimately rupturing utriculi is transformed into a hard, black body consisting of agglutinated spores; initially it is covered by a silvery membrane, that later flakes off. Ripe sori desintegrate into pieces. The spores are 13-23 µm long, they bear spines, up to 1.5 µm long, that are rather closely placed and don’t easily break off.
Cyperaceae, narrowly monophagous
Carex lasiocarpa, rhynchophysa.
C. lasiocarpa is the main host plant.
