The pigment responsible for the bright-yellow color of the stalk bases of Leccinum chromapes is methyl isoxerocomate, which is accompanied by lesser amounts of isoxerocomic acid and atromentic acid. In addition, 4ʹ-hydroxy- and 3ʹ,4ʹ-dihydroxyacetophenone, previously unreported as metabolites of Basidiomycetes, were isolated. The pink color of the cap skin is due to variegatorubin. This pigment is accompanied by chromapedic acid, a g-butenolide of biosynthetic interest representing a new dimerization mode of 4-hydroxyphenylpyruvic acid in Boletales.
