Is this really different from Suillus subalpinus M.M. Moser?
In a Google search the only hits I get for S. subalpinus sensu C.C. Cripps is the instant Name and Observation 235286.
Could the instant Name be a notation or transcription error from the notes for Observation 235286? Doubtful, as “sensu C. L. Cripps; DNA” is in the additional data in the Field Museum online database. http://emuweb.fieldmuseum.org/...
Perhaps the issue is the location and associate, i.e., Observation 235286 is west of the Cascades and associated with Pinus monticola versus Montana and associated with P. albicaulis_
