Serpula lacrymans 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 lacrymans" by Franz Xavier von Wulfen in 1781. It was transferred to the genus "Serpula" by Petter Karsten in 1884. The specific epithet is derived from the Latin words "serpula" for "creeping" (as in a serpent) and "lacrymans", meaning "making tears". "Serpula lacrymans" has a preference for temperatures of but can survive any temperature from . It is not clear how much light is
Pulvinic acid acid, isoxerocomic acid, variegatic acid, variegatorubin, xerocomorubin, chinomethide, methyl bovinate, pulvinone, badion A, norbadion A, bisnorbadiochinone A, pisochinone, and sclerocitrin. Pulvinic acid Pulvinic acid is a natural chemical pigment found in some lichens. Dimers of pulvinic acid have been found in the fungi "Scleroderma citrinum" and "Chalciporus piperatus". Hydroxypulvinic acid pigments (pulvinic acid type family of pigments) have been found in "Boletus" (e.g. "Boletus erythropus"), "Boletinus", "Chalciporus", "Gyrodon", "Leccinum", "Pulveroboletus", "Suillus" (e.g. "Suillus luteus", "Suillus bovinus", and "Suillus grevillei"), "Paxillus" (e.g. "Paxillus involutus"), "Serpula" (e.g. "Serpula lacrymans"), "Xerocomus" (e.g. "Xerocomus chrysenteron"), "Hygrophoropsis" (e.g. "Hygrophoropsis aurantiaca"), "Retiboletus" (e.g. "Retiboletus nigerrimus"), "Pulveroboletus"
