“…Calostomal (1) is structurally closely related to the polyene part of the boletocrocins (e. g. 3), a unique group of amino acid conjugates responsible for the bright colour of Boletus laetissimus and B. rufo-aureus [7]. In addition, the 2H-azepine alkaloids of the bolete Chalciporus piperatus are formed from an aminoketone precursor derived from a polyunsaturated heptaketide chain [8].…”

The North American stalked puffball Calostoma cinnabarinum (Boletales) owes its red-orange colour to the heptaene pigment calostomal. Its structure has been determined by 1 H and 13 C NMR spectroscopy of the corresponding methyl ester as all-trans-16-oxohexadeca-2,4,6,8,10,12,14-heptaenoic acid (1). Neither pulvinic acids nor other typical Boletales pigments could be detected in this fungus. The structural relationship of 1 to other polyene pigments from fungi is discussed.

“…Pigments of fruiting bodies: Fruiting bodies of fungi are often very colourful, which attracted the interest of chemists early on. [34] The investigations on these pigments revealed that they represent a huge variety of different compounds [34] including alkaloids, [35] aromatics, [36] polyenes [37] and even metal complexes. [38] However, the ecological role of these compounds is probably linked rather to their bioactivity than to their colour, although the bright colours of some mushrooms might be interpreted as a warning signal.…”

Like plants, fungi have evolved a variety of defence strategies in order to protect themselves against feeding mammals, insects and infection with parasitic fungi. In contrast to plants little is known on the chemical ecology of fruiting bodies of higher fungi, particularly those defence mechanisms which are induced upon wounding have only occasionally been recognised. Methods both for the detection of permanently present defence compounds and for the elucidation of wound-activated chemical defence mechanisms are discussed in this concept paper.

“…The species is characterized by the brilliant orange color of the pileus, hymenophore and stipe, which readily distinguishes this species from many other species of Boletaceae. Interestingly, Kahner et al (1998) detected unusual boletocrocin polyene pigments from the fruit bodies of the fungi, which account for the intense color. Like the genus Retiboletus Manfr.…”

Crocinoboletus, a new genus of Boletaceae (Boletales) with unusual boletocrocin polyene pigments

Crocinoboletus is described as a new genus of Boletaceae to accommodate Boletus rufoaureus and B. laetissimus, characterized by its brilliant orange color of basidiomata caused by the presence of unusual boletocrocin polyene pigments, bluish olivaceous staining of all parts when bruised, smooth basidiospores, and the pileipellis which has an interwoven trichoderm at the middle part of the pileus and a cutis at the margin of the pileus. Prior molecular phylogenetic analyses also confirmed the two taxa are not members of the genus Boletus s.s., but form a well-supported generic lineage within Boletaceae. Consequently a description, color photos of fresh basidiomata, line-drawings of microstructures and a comparison of Crocinoboletus with allied taxa are presented.
