Calostomal is an organic compound that has a carboxylic acid and an aldehyde group. It is a red-orange solid that is extracted from the mushroom Calostoma cinnabarinum, hence the name. The structure of this compound was confirmed by NMR and mass spectrometry of the methyl ester derivative.{{cite journal |author=Gruber G, Steglich W. |title=Calostomal, a polyene pigment from the gasteromycete Calostoma cinnabarinum (Boletales) |year=2007 |journal=Zeitschrift für Naturforschung B|volume=62 |issue=1 |pages=129–131 |url=http://www.znaturforsch.com/ab/v62b/s62b0129.pdf |doi=10.1515/znb-2007-0120 |s2cid=28501033 }} This compound is a highly conjugated polyene somewhat similar to the lycopene found in tomatoes.
