Paxillus involutus, the common roll-rim, is a fungus widely distributed
across the Northern Hemisphere; it has also been unintentionally
introduced to Australia, New Zealand, and South America. The brownish
fruit body grows up to 6 cm (2.4 in) high. It has a funnel-shaped cap
up to 12 cm (5 in) wide with a distinctive in-rolled rim and decurrent
gills close to the stalk. Genetic testing suggests that the fungus may
be a species complex rather than a single species. A common mushroom of
deciduous and coniferous woods and grassy areas in late summer and
autumn, P. involutus is symbiotic with the roots of many tree species,
reducing the trees' intake of heavy metals and increasing their
resistance to pathogens. Previously considered edible and eaten widely
in Eastern and Central Europe, the mushroom has been found to be
dangerously poisonous; in 1944, it killed the German mycologist Julius
Schäffer. It can trigger the immune system to attack red blood cells
with potentially fatal complications, including acute renal and
respiratory failure.
