 Tricholoma pardinum is found across Europe , where it is more common in the south . It is abundant in the Jura Mountains in eastern France . The species is found in Belgium and Germany , but has not been recorded from the Netherlands or the British Isles . A historical record from Estonia has been discarded because no herbarium specimens could be found . In Asia , it has been recorded from İzmir Province in southwestern Turkey , China , and Sado Island in Japan . It is found widely across temperate North America , where Santa Cruz County and Sierra Nevada in central California in the west of the continent , and the central Appalachians in the east form the southern limits of its distribution . T. pardinum is commonly associated with conifers in the Rocky Mountains and Pacific Northwest , and with tanoak ( Lithocarpus densiflorus ) and madrone ( Arbutus spp . ) in California . The mushroom can be abundant in some years , especially warmer years with higher rainfall , yet missing or rare for several years in between . In Europe , it is found on chalky soil in woodland with beech and fir in summer and autumn , where it prefers areas of some elevation . Although it may be found in groups or fairy rings , it most commonly occurs singly .
