Observation 775: Boletopsis smithii K.A.Harrison
When: 2006-09-30
No herbarium specimen

Notes: Found under conifers in the Echo Summit area, south of South Lake Tahoe. In a forested area near a large grassy clearing. The center of the grassy clearing was a seepage area, but this was 50-100 yards from where these were found.

The spot on the pores in the second shot was from KOH, which stained the pores a yellow brown.

7/16/2008 – Getting back to this one. I’m not a polypore type of guy, partially because I was taught most of what I know from Dennis Desjardin, and he is not a polypore type of guy, and also because I just don’t find that many of these. In this case, this is the only Boletopsis I’ve found anywhere, so its not something I know much about.

But this observation has been picked up by “Mushroom the Journal of Wild Mushrooming”, and was noted as interesting by Leon Shernoff there. Part of the interest was the “orange” color of the cap.

As part of this, I’ve gone back to the original photos and I’ve done a more careful color correction. Maybe this has reduced the “orange” color, I’m not sure, to me it didn’t have much of an orange in the first place. Not like some Lactarius or Hygrocybe, now those are orange. But perhaps for Boletopsis slight shadings are important. In any case, this does spark some interest in these, and it would good to find more and see what things look like in comparison.

Anyway, the initial comment was that as an orange Boletopsis this is a rare siting of B. skamaniensis (MtJoWM vol. 25 no. 4) , which in further comments this was equated with Albatrellus skamanius (MtJoWM vol. 26 no.1). The further comments go on to say that A. skamanius is more known from the NW, and was very rare, but with further study has been seen from more places now, and they site a paper. But with an orange color from the Sierras this is more probably Boletopsis smithii.

He mentions that B. smithii is about 2 inches in size, and these were 3-4 inches in size.

He mentions that at the foray it was interesting that this specimen seems to have been brushed off as just another weird color variant. I don’t think it was that conscious, it was more, hey looks like a Boletopsis? You know anything about Boletopsis? Nope not me, what does Arora say, don’t know it looks like B. subsquamosa is what he suggests. Great, close enough for me, lets keep going…

I would like to thank the comments in “Mushroom the Journal” from Leon Shernoff and Jim Ginns about this observation, there is a number of interesting things about Albatrellus and Boletopsis mentioned in the articles, and I will make an effort to be careful about Boletopsis that I find in the future. (Since I didn’t put much care into finding this one…)
