One of the things us Americans have noted (Dr. Lorelei Norvell, 1995 article) is that many of the species taken largely for granted are actually complexes of different species. For example, until the last 15 years Cantharellus cibarius was actually cultivated by Dr. Eric Danell, AND compared to the original collection of C. cibarius by Fries, it was assumed that all golden-colored chanterelles of the Northern Hemisphere were all the same species. But after Danell’s DNA comparison of collections from Europe, Western US, and eastern US and Canada, the name C. cibarius was suddenly a very uncommon species, found only in Sweden, Holland, and one location in England. The C. formosus identification was a direct outgrowth of that sudden spurt of scientific knowledge. Dr. Norvell has stated that there are probably in the neighborhood of 2 million different fungal species in the Pacific Northwest. Only about 10 percent of these are currently identified in science. The rest continue to be found. Dr. Bill Dennison’s idetification of 50+ endophytic fungi (fungi that live in the needles of Douglas fir) is just another case in point.

Boletopsis smithii ?

For all I know, “Boletopsis subsquamosa” is a nomen dubium. The only possible interpretations are: a synonym to Boletopsis grisea, or just extremely dried out and scaly specimen of Albatrellus ovinus. This according to the existing species where this one was supposed to grow.

I also know that the name “subsquamosa” was used earlier as a synonym to Boletopsis leucomelaena/grisea, long before we realized that they were two different species, but it seems like you americans are still using it for every Boletopsis sp..

This one, with the orange brown colour on the cap, fits better with the name Boletopsis smithii, originally described from USA, but I don’t know it well enough to call it that. There could be other Boletopsis species in the western US, of course.
