Xerocomus chrysenteron

The fruiting bodies of Pulveroboletus auriflammeus collected in Japan contain a series of extensively methylated atromentic acid and xerocomic acid derivatives, several of them in chlorinated form 474). The presence of traces of a chlorinated xerocomic acid had been noted before in sporophores of Xerocomus chrysenteron 607).

Variegatic and xerocomic acids co-occur with atromentic acid (57) in Xerocomus chrysenteron 56), and atromentic acid has also been isolated from cultures of the mushrooms Paxillus atrotomentosus 61), Clitocyre illudens 64) and Leccinum aurantiacum 65).
