Serpula himantioides Serpula himantioides Serpula himantioides is a species of fungus that causes damage to timber referred to as dry rot. It is a basidiomycete in the order Boletales. It has been found on all continents except for Antarctica. Recent molecular work demonstrates that "S. himantioides" is a species complex including multiple cryptic lineages. The fungus was first described in 1818 by Elias Magnus Fries as "Merulius himantioides". Petter Karsten transferred it to the genus "Serpula" in 1884. "Serpula himantioides" is a fungal pathogen within the division Basidiomycota. It produces thin, resupinate (inverted), membranous fan-like basidiocarps that are brownish in color and
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"
