no records from west

We don’t have any records of the undescribed species from west of the great plains (or from the southeast), so it would be interesting to see the western one.

Just saw my parents, and observed another Laetiporus that my father found on a Bigleaf maple log. Had 4 fruiting bodies on the log, each at least 2 pounds in size, and with the definate black stain on the edges, as this one does. I did not notice any black staining on cut or torn surfaces, but there was black on fresh edges where handled. I thought it was another specimen of Laetiporus sulphureus var. albidum, since the specimen I saw had a bleached appearance after only a week. But after Tom’s comments, I’m going to have to re-think that opinion.

Thanks, Tom!

I’m pretty sure this is an undescribed species of Laetiporus. We have seen it a dozen times or so in Wisconsin and east of the great plains. It has white pores but causes a butt rot. (unlike L. cincinnatus, which has white pores and is a root rot). See http://botit.botany.wisc.edu/toms_fungi/jul2001.html

This undescribed species is NOT delicious. It is usually tough, often bitter, and stains BLACK when you bruise or cook it— I can see a little of that on the photos.
