Where is it from?
There is "Ida" written on the paper which could refer to Idaho . Below there is the word "desert". There are deserts in Idaho like Owyhee Desert or Yp Desert in Owyhee County.
So at least "Idaho" could be plausible. Three species of can be found in that region
- Clitocybe irina
- Clitocybe lepista
- Clitocybe nuda
This text also says
The primary collector in the Owyhee region was Mrs. Ellen Trueblood formerly of Nampa,Idaho
The same name is given here.
Looks like the Ted Trueblood Wildlife Area, Idaho
So that would be in Owyhee County. http://fishandgame.idaho.gov/ifwis/ibt/site.aspx?id=SW25
