Omphalotus olearius

O. olearius fruiting bodies exhibiting blue-green bioluminescense

Description and Significance

O. olearius is a mushroom reminiscent of a chanterelle mushroom. Like the chanterelle, its fruiting bodies have an appealing taste and odor, leading many people to consume them. However, unlike the chanterelle, O. olearius contains toxic compounds which can cause severe stomach cramps, vomiting, and diarrhea. In addition, it exhibits significant bioluminescence as well, which has resulted in it becoming known as the "Jack-o-lantern" mushroom. One point of interest is that the toxic compounds produced by O. olearius have been shown to contain an anti-cancer chemical known as irofulven. Currently, the mechanism of irofulven's anti-cancer properties is not well-understood, but it appear to be unique from other anti-cancer agents. [1]

Structure, Metabolism, and Life Cycle

Interesting features of its structure; how it gains energy (how it replicates, if virus); what important molecules it produces (if any), does it have an interesting life cycle?

Ecology and Pathogenesis

Natural habitat (soil, water, commensal of humans or animals?)
If relevant, how does this organism cause disease? Human, animal, or plant hosts? Important virulence factors, as well as patient symptoms.
