The relationships ofPisolithus (Sclerodermataceae) to other fleshy fungi with particular reference to the occurrence and taxonomic significance of hydroxylated pulvinic acids

Abstract

In the light of the discovery of hydroxylated pulvinic acids in the gasteromycetePisolithus arhizus, a possible relationship with the boletoid fungi and their relatives is explored. Biogenetic inter-relationships are indicated, including the host range ofApiocrea chrysosperma, and the distribution of phenylpyruvate-derived pigments offered in schematic form.
