![]() ![]() Jack-o’Lantern is a poisonous mushroom and when ingested can cause diarrhoea and vomiting. It is found in clumps usually on large stumps of wood or fallen branches and the decaying roots of deciduous trees. The Jack-o’Lantern mushroom is large and strikingly bright orange. Original studies also suggested that there was a synonymy between Omphalotus illudens and Omphalotus olearious however, DNA examination confirms they are two distinct species. Investigations of the properties from this mushroom were published back early in the 1900s when this fungus was more commonly known then as Clitocybe illudens. Accessed 16 October, 2020.The scientific name for Jack-o’Lantern is Omphalotus illudens, this mushroom is a basidiomycete.

This property was exploited by the company MGI Pharma to develop an illudin-derivative called Irofulven for use as a cancer treatment. Damage in non-transcribed DNA areas is left unrepaired by the cell. This block can only be relieved by a repair system called nucleotide excision repair. Inside human cells, illudin S reacts with DNA and creates a type of DNA damage that blocks transcription. The cytotoxic effect of illudin is of interest for treating some cancers, but illudin itself is too poisonous to use directly so it must first be chemically modified. Muscarine has also been indirectly implicated in toxicity, but modern studies to demonstrate its presence in O. In addition to their antibacterial and antifungal effects, illudins appear to be the cause of human toxicity when these mushrooms are eaten raw or cooked. The poisonous chemical compounds illudin S and illudin M were isolated from Omphalotus illudens. Although some older literature claims the name is synonymous with Omphalotus olearius, phylogenetic analysis confirms the two as distinct species. Unlike chanterelles, the Eastern Jack-o’-lantern is poisonous to humans when eaten, whether raw or cooked, and typically causes vomiting, cramps, and diarrhea. Omphalotus illudens is sometimes confused with edible chanterelles, but can be distinguished by its thicker, fleshier appearance, tendency to form large clusters, and clearly separated caps when young. It is believed that this display serves to attract insects to the mushroom’s gills during nighttime, which can then distribute its spores across a wider area. ![]() This green glow has been mentioned in several journal articles, which state that the phenomenon can persist up to 40-50 hours after the mushroom has been picked. Its gills often exhibit a weak green bioluminescence when fresh. ![]() Omphalotus illudens, commonly known as the eastern jack-o'lantern mushroom, is a large, orange mushroom that is often found in clumps on decaying stumps, buried roots, or at the base of hardwood trees in eastern North America. ![]()
