 Chorioactis geaster has a disjunct distribution , and has only been collected from Texas and Japan . The first reported collection in Japan was in Kyushu in 1937 , and then it was not collected again in that location until thirty @-@ six years later . In 2006 , it was observed in a humid forest near Kawakami , Nara Prefecture . The fungus 's natural habitat in Japan is disappearing because of the practice of deforestation and replanting with Japanese cedar ( Cryptomeria japonica ) . This rare mushroom has been put on the list of threatened species in Japan . In Texas , the fungus has been reported in Collin , Hays , Travis , Dallas , Denton , Guadalupe , Tarrant and Hunt counties . Travis , Hays , and Guadalupe counties are in central Texas , while the remainder are clustered together in the northeastern part of the state . Although the species is considered rare due to its globally restricted distribution , it may be locally abundant .
