Fruiting body: 3-10 cm tall; yellow when moist, orange-yellow when dry; variable in shape - may be cupulate, spathulate, resupinate or coralloid; upper branches often forked; smooth.
Flesh: yellow, gelatinous, tough.
Spores: hyaline, smooth, allantoid or elongated, non-amyloid, 7-10 x 3-4.5 µm.
Habitat: saprobic; several to many on dead conifer logs and stumps; Aug - Nov.
The tough, gelatinous texture of Calocera viscosa helps to distinguish it from the more brittle coral fungi.
Bioactive compounds
The indole metabolite 5-hydroxytryptophan was found in Calocera viscosa mycelium grown in shake cultures (Kholmunzer et al., 2000).
Polysaccharides extracted from the mycelial culture of C. viscosa and administered intraperitoneally into white mice at a dosage of 300 mg/kg inhibited the growth of Sarcoma 180 and Ehrlich solid cancers by 90% (Ohtsuka et al., 1973).
