 L. indigo is distributed throughout southern and eastern North America but is most common along the Gulf Coast , Mexico , and Guatemala . Its frequency of appearance in the Appalachian Mountains of the United States has been described as " occasional to locally common " . Mycologist David Arora notes that in the United States , the species is found with ponderosa pine in Arizona , but is absent in California 's ponderosa pine forests . It has also been collected from China , India , Guatemala , and Costa Rica ( in forests dominated by oak ) . In Europe , it has so far only been found in southern France . A study on the seasonal appearance of fruiting bodies in the subtropical forests of Xalapa , Mexico , confirmed that maximal production coincided with the rainy season between June and September .
