Calocera cornea - (Batsch) Fr. Small Stagshorn

Phylum: Basidiomycota - Class: Dacrymycetes - Order: Dacrymycetales - Family: Dacrymycetaceae

Calocera cornea - Small Stagshorn

This unbranching (or only very rarely branching) jelly fungus, with tiny fruitbodies usually shorter than the thickness of a finger, can be seen on trunks and twigs of deciduous broadleaf trees.

Small Stagshorn looks rather like a club fungus; however, it is much less brittle and microscopic examination reveals that it has distinctive Y-shaped basidia, which are diagnostic characteristics of members of the order Dacrymycetales.

Fairly common and widespread throughout Britain and Ireland, although easily overlooked because of its small size and preference for damp shady places, this gregarious wood-rotting fungus is found in most parts of mainland Europe as well as in many other regions of the world including North America.

Taxonomic history

In 1783 German mycologist August Johann Georg Karl Batsch (1761 - 1802) described this little wood-rotting fungus and gave it the binomial scientific name Clavaria cornea. Nearly half a century later, in 1827, the great Swedish mycologist Elias Magnus Fries, who had established the genus Calocera in 1821, renamed this species as Calocera cornea, which has remained its accepted scientific name up to the present time.

Synonyms of Calocera cornea include Clavaria cornea Batsch, Clavaria striata Hoffm., Tremella palmata Schumach., Corynoides cornea (Batsch) GrayCalocera palmata (Schumach.) Fr., and Calocera striata (Hoffm.) Fr.


Calo- as a prefix means beautiful, while the extension -cera comes from ancient Greek and means 'like wax', so that the genus name Calocera translates to 'beautiful and waxy'. The specific epithet cornea is derived from Latin, and it means 'horn'. Beautiful waxy horns... perhaps not such a bad description for these little fungi.

Identification guide

Close-up of Calocera cornea - Small Stagshorn


Gelatinous and rubbery; yellow (in dry weather becoming more orange); greasy and viscid, with curved, blunt or pointed horns that are only very rarely forked at the tips; clustered in non-merging groups; 2 to 12mm tall and typically 1 to 2mm dia.



Ellipsoidal to sausage-shaped, smooth, 7-10 x 2.5-4um; hyaline; inamyloid; often becoming 1-septate when fully mature (developing a single cross wall).

Spore print

White or very pale yellow.


Shaped like a tuning fork; 2-spored.


Not distinctive.

Habitat & Ecological role

On rotting trunks and stumps of dead broadleaf trees and very occasionally on conifers.


Fruiting through most of the year in Britain and Ireland, but particularly prevalent during the autumn months.

Similar species

Calocera viscosa is much larger and has branches emanating from a short trunk.

Calocera pallidospathula is initially translucent white, and only its tips become yellowish with age.

Calocera cornea could also be confused with some of the Ramaria species of coral fungi, but the greasysurface and rubbery texture are obvious distinguishing features.

Culinary Notes

Although not known to cause poisoning, Small Stagshorn fungus is generally regarded as inedible because of its gelatinous texture, lack of flavour and minuscule proportions.
