Calocera cornea is a jelly fungus that grows on decaying wood. It is a member of the Dacrymycetales, an order of fungi characterized by their unique "tuning fork" basidia.

Its yellow, finger-like, tapering basidiocarp

Basidiocarp

In fungi, a basidiocarp, basidiome or basidioma , is the sporocarp of a basidiomycete, the multicellular structure on which the spore-producing hymenium is borne. Basidiocarps are characteristic of the hymenomycetes; rusts and smuts do not produce such structures...

s are somewhat gelatinous in texture. In typical specimens the basidiocarps become up to 3 mm in diameter, and 2 cm in height. The hymenium

Hymenium

The hymenium is the tissue layer on the hymenophore of a fungal fruiting body where the cells develop into basidia or asci, which produce spores. In some species all of the cells of the hymenium develop into basidia or asci, while in others some cells develop into sterile cells called cystidia or...

covers the sides of the basidiocarps, each basidium producing and forcibly discharging only two basidiospores.
