Brauner Eichelbecherling

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.

Haselkätzchen-Stromabecherling

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.
