A spring cup fungus with small brown cups on long stalks that rise from a black sclerotium buried in the soil. It is a parasite of wood anemone, killing its host, so it can fruit some distance from living plants. Formerly Sclerotinia tuberosa.
Edibility unknown; not a food. It is small and is a plant pathogen.
Never eat a wild mushroom based on a web page — confirm with an expert.
Habitat
Parasitic on wood anemone (Anemone nemorosa) and occasionally garden anemones such as A. blanda; reported on lesser celandine (Ranunculus ficaria), though this is not confirmed. In damp places in early spring, often in anemone patches, especially where plants are stunted or missing.
