That CDC map displays what appears to me to be an unusual pattern of cases though out the states.
I can understand the southern tier of states up to Texas as these are warm and wet climates. Further west is a lot drier, so I don't understand those outbreaks.
As for that column of states from Florida up through Michigan and Minnesota, I can understand that too due to the Mississippi Valley and the forest ecosystems east of the Plains states.
The Great Plains west of the Mississippi River makes sense to me, except when you get up into the Pacific Northwest. Idaho has no cases and it has a similar climate and ecology as West Michigan, so what is the difference when these fungi are so incredibly common, particularly in the Midwest? Altitude? Except that doesn't explain the Great Plains states.
If I were to look deeper, I would look at population more than climate and geography, maybe that is more of a factor in the spread of this fungus.
