Recognized by sight: similar to S. kaibabensis in habitat and macro features: yellowish cap and pores, reddish dots on stem, vinaceous stains at base. I couldn’t find much data on either species but what exists describes both as being mycorrhizal with conifers, especially Pinus ponderosa. The online photos associated with the Thiers description on Mycoportal are by Dr. Scott Bates and differ mostly in terms of the shape and size of the stem it seems to me. His photo of S. occidentalis is more like those on this obs in my opinion.
