Most field guides record this jelly-like fungus as inedible because it is tasteless, tough and leathery rather than perilously poisonous. Saprobic, on deciduous hardwoods particularly dead and decaying elms and Beech very occasionally on living trees.Īuricularia mesenterica can be found throughout the year, but it is most prevalent in lateĪuricularia auricula-judae, commonly known as Jelly Ear Fungus, is nearly always found on dead Elder.Īlthough tripe is edible when cooked, Tripe Fungus is not. Sausage shaped (allantoid), 15-17 x 6-7µm. ![]() Inside the fruitbody the flesh is gelatinous but rubbery - so tough that it is usually much easier to tear the whole of a fruitbody from its substrate than to remove just a small piece. The fertile underside is initially smooth with a whitish bloom, but it becomes wrinkled and reddish-brown to ochre with age. The upper (infertile) surface of the lobed fruitbody isĭowny or hairy and zoned in various concentric bands of purple, brown, ochre, grey and white. Identification guideīracket-like but attached only loosely to the host timber, the fruitbodies start off as pale rubbery buttons but expand to typically 3 to 7cm across, often merging into compound structures sometimes running along fallen trunks and branches for more than a metre. The type species of the genus Auricularia. (Now you surely must realise that I really am talking a load of tripe!)Īuricularia mesenterica, commonly known as Tripe Fungus (but in the past quite often referred to as the Grey Brain Fungus), is The specific epithet mesenterica is a latinised adjective derived from the Ancient Greek word mesenterion meaning 'middle intestine'. EtymologyĪuricula is a Latin word meaning ear - a reference to the ear-like shape of mature fruitbodies of most fungi in this small genus. ![]() The currently-accepted scientific name Auricularia mesenterica dates from an 1822 publication by Christiaan Hendrik Persoon.Īmong the many synonyms of this rubbery woodland fungus are Helvella mesenterica Dicks., Tremella violacea Relhan, Auricularia tremelloides Bull., Auricularia corrugata Sowerby, Gyraria violacea (Relhan) Gray, Stereum mesentericum (Dicks.) Gray, Auricularia lobata Sommerf., and Tremella corrugata Schwein. Tripe Fungus was described scientifically in 1785 by British mycologist James J Dickson (1738 - 1822), who gave it the binomial scientific name Helvella mesenterica. Looney et al) to this species in North America. Distributionįairly frequent in Britain and Ireland, but most often recorded in southern England, Tripe Fungus occurs also in many countries of mainland northern and central Europe and is present in parts of Australia. Like most if not all jelly fungi, Auricularia mesenterica generally favours damp shady sites. Tripe Fungus is quite variable in appearance, depending on the state of decay of its host timber as well as the developmental stage of the fruitbodies. The so-called Jelly Fungi are not really a taxonomic group but more a rag-tag of basidiomycetes with jelly-like textures, although few are a soft as the jelly we eat with custard. It occurs most commonly on dead elm trees and onįallen elm trunks and branches, and so was particularly common after Dutch elm disease had ravaged the elms of Britain and Europe during the second half of the 20th century.
