Auricularia mesenterica

Auricularia mesenterica, commonly known as the tripe fungus, is a species of fungus in the family Auriculariaceae. Basidiocarps (fruit bodies) grow in undulating densely-packed shelves that adopt a partially resupinate form.[1] A. mesenterica feeds saprotrophically on a number of woody substrates in deciduous forests.

Taxonomy and etymologyEdit

Auricularia mesenterica was described by James Dickson as Helvella mesenterica in 1785,[2] and transferred to the genus Auricularia by Christiaan Hendrik Persoon in 1822,[3] Further genetic analysis has revealed an Auricularia mesenterica species complex, with A. mesenterica as the basal species.[4] The specific epithet is a Latin adjective formed from the Ancient Greek word μεσεντεριον (mesenterion), "middle intestine", from μεσο- (meso-, "middle, center") and εντερον (enteron, "intestine"), referring to its shape.[5]


This species forms bracket-like fruit bodies that first appear pale, rubbery, and button-like in shape, expanding to typically 3 to 7 cm across and hardening with age. The fruit bodies often merge into compound structures sometimes running along fallen trunks and branches for more than a meter. The upper surface is gray to brown, tomentose to hispid with concentric zones, while the underside is thickly gelatinous, irregularly folded radially, wavy and putty-like, and reddish-brown. The spore print is white.[6][7]

Distribution and habitatEdit

This species is considered a cosmopolitan species and grows on many different species of angiosperm wood, such as poplar, elm, and ash, typically in summer to fall.[8] It is a common species in Europe, but rare in the Americas and China.[9][4]


Young A. mesenterica
Mature A. mesenterica

Before the fruit body fully matures and hardens, young specimens are edible, but in some local populations, these fungi tend to bioaccumulate high levels of heavy metals from their environment.[10] A. mesenterica has shown to have high levels of phenols, flavonoids, and antioxidant activity, having potential as antitumor agent[11]
