Ciboria coryli is a saprotrophic cup fungus in the family Sclerotiniaceae, found in temperate Europe. It typically fruits on the fallen catkins and nuts of hazel (Corylus avellana) in moist woodland, hedgerow, and scrub habitats, emerging from sclerotia within decaying plant material. The fruiting bodies are stalked discs, pale to medium brown, and rarely exceed one centimeter in diameter. Like other members of the genus, Ciboria coryli is a specialist on a particular plant substrate, in this case hazel reproductive material, which determines its seasonal and geographic distribution. It is classified as Least Concern, with populations stable in regions where hazel woodland persists. Hazel coppice and mixed deciduous woodland across central and western Europe provide suitable habitat. The species name coryli directly references its host plant genus. Identification from related species requires microscopic examination of spore size and shape, as well as the character of paraphyses and excipular cells. Ciboria coryli contributes to the decomposition of woodland leaf litter and the cycling of nutrients from fallen organic matter back into the soil. As with many small discomycetes, it is under-recorded relative to its actual abundance. Conservation of hazel-rich woodland habitats benefits this species alongside a wide range of other specialist fungi and invertebrates associated with hazel.

Ciboria rufofusca is a small discomycete in the family Sclerotiniaceae, recorded from temperate Europe. The species is a saprotrophic cup fungus that fruits on fallen plant material, with records suggesting an association with catkins or mast of various deciduous trees, consistent with other members of the Ciboria genus. The fruiting bodies are stalked cups with a reddish-brown to ochre coloration, giving the species its name, which translates roughly as red-brown Ciboria. The species has not been formally assessed by the IUCN. As with many small discomycetes, Ciboria rufofusca is likely under-recorded due to its inconspicuous size, brief fruiting season, and the specialist knowledge required for identification. Microscopic features—spore morphology, paraphysis structure, and excipular anatomy—are essential for distinguishing this species from close relatives. The genus Ciboria belongs to Sclerotiniaceae, a family that also includes major plant pathogens, though Ciboria species themselves are saprotrophic decomposers rather than parasites. European temperate woodlands support a diverse community of substrate-specific discomycetes, many of which remain poorly documented. The conservation status and population trends of Ciboria rufofusca are unknown, as systematic surveys of small cup fungi across Europe are limited. It likely plays a role in decomposing woodland organic matter and cycling nutrients within forest floor ecosystems.
