Eastern Jack-o'-Lantern
The eastern jack-o'-lantern is a bright pumpkin-orange mushroom that fruits in dense, showy clumps at the foot of hardwood stumps in late summer and autumn. Its fresh gills famously give off a faint green glow (bioluminescence) in full darkness. Ecologically it is a decomposer of dead hardwood and a weak parasite on living roots, so it recycles woody debris but can also signal internal decay in an old tree.
It is toxic and is the classic dangerous double for the golden chanterelle. The differences are clear once known: the jack-o'-lantern grows in tight clusters on wood, has true thin, sharp-edged gills, and has a distinct cap-and-stem shape, whereas the chanterelle grows singly from soil with blunt, forked false-gill ridges. Eating it causes severe cramps, vomiting, and diarrhoea. Enjoy the autumn colour and the glow, and leave it where it stands.
Toxic
Toxic — contains muscarine and illudin compounds that cause severe vomiting, cramps, and diarrhoea within a few hours. The most common mushroom mistaken for the golden chanterelle. Tell them apart by its true sharp-edged gills, its dense clustered growth on wood, and its faint green glow, versus the chanterelle's blunt forked ridges and solitary growth from soil.
Golden chanterelle (Cantharellus cibarius)
Breaks down dead hardwood at stumps and buried roots. Its appearance on a living tree's base can flag internal rot worth monitoring for limb safety.
