It is my understanding, based on Arora’s 2008 paper linked to above, that the native summer/fall king bolete on the west coast has been defined as B. edulis var. grandedulis, to distinguish it from the European B. edulis. Other edulis-group fungi in the PNW would include the spring king B. rex-veris (also defined in Arora’s paper), B. barrowsii, non-native boletes on introduced ornamental trees, etc.

What features in my observation lead you to var. grandedulis? Do you have a key or a link to share?
