Serpula lacrymans 2016). The genus "Serpula", including "S. lacrymans" and "S. himantoides", is known to produce three classes of chemical compounds: pulvinic acid-type family, himanimides, and polyine acids. Within the pulvinic acid-type family, atromentin-derived compounds include variegatic acid, xerocomic acid, isoxerocomic acid, atromentic acid, variegatorubin, xerocomorubin, and other variants of these pigments. Pulvinic acid-type family pigments were found to be secreted during co-incubation with various bacteria. Serpula lacrymans Serpula lacrymans is one of the fungi that cause damage to timber referred to as dry rot. It is a basidiomycete in the order Boletales. The species was first described under the name "Boletus
Nemapogon granella are uniformly greyish-brown and surrounded by a fringe of long hairs. On the head, the adults have a tuft of yellowish-white hairs. The caterpillar larvae eat rotting wood in the wild, though they prefer bracket fungi, usually Polyporales. Their mainstay food included Polyporaceae such as sulphur polypore ("Laetiporus sulphureus"), dryad's saddle ("Polyporus squamosus") or turkey tail ("Trametes versicolor"), as well as Fomitopsidaceae, e.g. birch polypore ("Piptoporus betulinus"). But they have also been found on "Serpula lacrymans" of the quite unrelated Boletales. Larvae in association with humans will feed on a variety of dry organic material, such as dried fruit (e.g.bilberries,
