and in my experience S. granulatus has a darker/browner cap and lighter/more yellow pores than this obs and it lacks the vinaceous staining at the base of the stem that S. occidentalis has. This obs seems to fit Thiers’ description of the S. occidentalis he found in Arizona. See: http://mycoportal.org/...

S. kaibabensis is also possible as Thiers’ macroscopical descriptions of both are very close but the recent online photos by Dr. Scott Bates of ASU seem to favor S. occidentalis. See: http://mycoportal.org/...
