Ciboria batschiana is a saprotrophic cup fungus in the family Sclerotiniaceae, distributed across temperate Europe and parts of western Asia. It is one of the more frequently recorded members of the genus and typically fruits in autumn on fallen acorns and mast of oak (Quercus) species, occasionally also on beechnuts and other hard mast. The fruiting bodies are small, stalked discs with a concave to flat spore-bearing surface, ranging from pale buff to chestnut brown, and reaching up to about one centimeter across. The stalk arises from a sclerotium—a compact mass of fungal tissue within the decomposing nut—which enables the fungus to persist through unfavorable conditions. Ciboria batschiana plays a role in the decomposition of hard mast in woodland leaf litter and is categorized as Least Concern. The species is widespread but rarely abundant, and tends to be locally distributed depending on mast production years. It is associated with mature oak and beech woodland across its range. Taxonomic placement within Sclerotiniaceae has been confirmed by molecular studies. As with many small discomycetes, accurate identification requires microscopy to examine spore dimensions, paraphysis morphology, and the character of the excipular tissue. The species name honors the eighteenth-century naturalist August Johann Georg Karl Batsch.

Ciboria betulae is a small discomycete fungus in the family Sclerotiniaceae, associated with birch (Betula) trees across temperate Europe and northern Asia. The species fruits on fallen birch catkins, seeds, or occasionally on decaying birch wood in moist woodland habitats and riparian zones. Its fruiting bodies are typical of the genus: small, stalked cup fungi with a pale to medium brown, concave disc surface. Ciboria betulae is saprotrophic, breaking down plant debris and contributing to nutrient cycling in birch woodland ecosystems. The species name clearly references its host association with Betula. It is classified as Least Concern, reflecting a distribution that is wide, though perhaps locally patchy, across birch-dominated forests and woodland edges. Birch catkins provide a specific substrate window in late spring and early summer after they fall, meaning the fruiting season of this species is typically brief and easily missed. Microscopic features including ascospore dimensions and shape, paraphysis morphology, and excipular tissue help differentiate Ciboria betulae from closely related species on other substrates. The genus Ciboria encompasses multiple species each associated with particular plant substrates, representing a degree of substrate specialization unusual among saprotrophic cup fungi. Records are scattered but consistent across the temperate birch belt of Eurasia.
