Ciboria amentacea is a small cup fungus in the family Sclerotiniaceae, found across temperate Europe. This inconspicuous discomycete produces tiny, stalked, cup-shaped apothecia that emerge in late winter to early spring, typically from the catkins (aments) of alder (Alnus) or willow (Salix) that have fallen into standing water or wet soil. The fruiting bodies are pale brownish to tan, rarely exceeding a few millimeters in diameter, and are easily overlooked. The species name amentacea derives from the Latin word for catkin, reflecting its substrate specificity. Ciboria amentacea is saprotrophic, decomposing plant material in riparian and wetland habitats, contributing to nutrient cycling in these sensitive ecosystems. It has not been formally assessed by the IUCN. The genus Ciboria belongs to the broader Sclerotiniaceae family, which also includes economically important plant pathogens; however, Ciboria species are generally not regarded as pathogenic. Records of this fungus are scattered across central and northern Europe, with the fruiting season heavily dependent on winter temperatures and snowmelt timing. Its early spring phenology makes it an important early food source for springtail and mite communities. Identification requires microscopic examination of spore morphology and paraphysis structure.
