Found growing on old Western hemlock stumps and more commonly on Vine maple stems in contact with the ground, often partially overgrown by deep moss. Notice black stipe and blueing portion of cap, which I have not seen in a description before. Size: 2-7 inches across cap. Height: 2-5 inches. Flesh thin, pores shallow and decurrent.

that had been cut 2-4 years prior; or Westrn hemlock stumps that were over 30 years old (extremely well rotten). Smaller specimens (2 inches diameter) were on small stems/twigs; larger specimens were on larger stems (up to 3 inches diameter, which is pretty large for a vine maple). I was collecting one of everything I found that day, just because I was preparing for the OMS show on Oct. 18, and wanted to have other opinions of what I came across. I do sometimes (rarely) find Polyporus varius in or near the same area. There’s 2,000 feet elevation difference from where national forest begins to the top of Larch Mountain. There are many, many species of both hardwoods and conifers in this rich zone. OMS members have been speculating there are multiple species of Polyporus in this area, and like Tom, have been hoping someone would examine the material already in the OMS Herbarium. I still have the specimens I collected that day, and am debating whether to add them to the OMS Herbarium, or send them to the OSU Herbarium for further study.
This looks different from the P. Badius in The east. The P. badius in the east are much larger. some a foot across. The Black stem only is half way up There is a P.varius and it is small and has black all the way up the stem also i have seen it blueing in the cap before. But those usually grow on hard wood twigs.
The distinctive feature should be no clamps on the hyphae or the bases of the basidia. Someone needs to work on comparing western with eastern Polyporus. there are some masquerading as the others.
