Calocera cornea (Latin Calocera cornea) is a species of Basidiomycota fungi (Basidiomycota) of the Dacrymycetaceae family.
Fruit body: Horn-or clavate, small (height 0.5 – 1.5 cm, thickness 0.1 – 0.3 cm), isolated or fused at the base with others, then, as a rule, not branching. Color – light yellow, egg; may fade to dirty orange with age. The consistency is elastic-gelatinous, rubbery.
Spore powder: White (colorless spores). The spore-bearing layer is located almost on the entire surface of the fruiting body of the fungus.
Distribution: Horny calocera is an inconspicuous fungus, widespread throughout. It grows on damp, thoroughly rotten hardwood, less often conifers, from mid or late July to November (or until the first frost, whichever comes first). Due to the general inconspicuousness and little interest for a wide circle of amateurs, information on the timing of fruiting may not be entirely accurate.
Similar species: Literatures compare Calocera cornea to close but less common relatives like Calocera pallidospathulata, which has a light 'stem' on which spores do not form.
Edible: It's hard to say for sure.
Notes: What is good about gummy calocera is that it is probably one of its kind, and therefore easily identifiable. (To everything else – both finding and photographing, it lends itself somewhat worse.) And it would be very disappointing if among the small yellow horn-shaped mushrooms that sprinkle from time to time on oak stumps, there were many difficult to distinguish and at the same time not related species. Let's hope this is not the case and nature is fair.
