. It has also been recorded in Taiwan. A recent study of this species indicates that ''S. subaureus'' associates with both deciduous and conifer trees in eastern North American forests. The spores of ''S. subaureus'' will not germinate in the presence of only deciduous tree roots. Instead, they require the presence of a conifer host tree (preferably ''Pinus'') to germinate, but will then colonize and persist on deciduous hosts via mycelial extension. The species is edible.
