Observation 169156: Boletus roseipes
When: 2014-07-04
No herbarium specimen

Notes: Singular specimen in forest of hemlock, birch, and other hardwoods. B. miniato-olivaceus growing in the vicinity. So I did consider this possibly being a very faded example of mini-o (collected after a heavy rainfall). But, other than cap color, there are a few things that eliminate mini-o: strong bluing on pores and all cut context, KOH dull orange on cap surface (several examples of mini-o all turned olive with KOH on cap). Spores are similar to mini-o, with quotient averaging a bit larger for the mushroom featured in this obs.

Second micro-photo shows what appear to be cystidia that match the roseipes description put forth in B/R/B… long, thin, a bit thicker in the mid-section.

Upper stipe pale without observable reticulations.

I have found solitary examples of this type at the same location in the past. B. inedulis and B. calopus are other names I have considered.
