The hornlings ( Calocera ) are a genus of mushrooms from the family of gelatinous tears . They include types with gelatinous, predominantly yellow to bright orange colored, horn-shaped fruit bodies . They colonize dead wood and produce different types of rot , depending on the substrate .

The type species is the sticky hornling ( Calocera viscosa ).


Macroscopic features

The tough, gelatinous fruit bodies have strong roots and often have a sticky surface. They are predominantly colored yellow to orange by carotenoids .

Microscopic features

The structures are largely covered by the spore-forming fruit layer. The 3-layered meat consists of a central core of compact hyphae , which is surrounded by a loose hyphae layer and finally covered by the compact fruit layer. The hyphae of European species do not have buckles . There are also no cystids in the hymenium. The smooth-walled spores show 1–3 transverse walls at maturity  and show no color reaction ( inamyloid ) when they come into contact with iodine solution .


Hornlings live saprobion table on hardwood and softwood. They are often classified as brown rot fungi in the literature . Keith Seifert, who investigated wood degradation by Dacrymycetales species, gives several types of rot for hornlings , sometimes even for one and the same species depending on the wood species populated.


There are around 15 species worldwide. 5 species occur in Europe or are to be expected there:
