Introduction
abundant common uncommon rare - colour codes match my Pictorial Key and are my opinions and probably reflect my bias of living in W WA. Rare species may be locally common in certain places at certain times. Click here to download the FASTA data of all my DNA sequences |

Boletopsis
Known as Kurotake in Japan, but not consumed nearly as often here, as its bitter and taste and tough consistency require long soaking in brine. These are white stemmed polypores of uniform consistency that turn black when handled or in age. Mycorrhizal.
Boletopsis grisea NY - starts out white to grey and darkens in age. A pine associate. Sometimes green tinged specimens are found. Those should be sequenced to see if they are different. Boletopsis PNW01 - Collections that start out with a fairly dark cap when young, thought to be Boletopsis leucomelaena EU, a spruce associate, instead turned out to be this unnamed species, a fir and hemlock associate. B. leucomelaena has not been shown to occur in the PNW, so any collections found under spruce should be collected to see what they are. Boletopsis smithii WA - known only from the type collection, described in 1975 but with orange tones. It probably represents an aberrant collection of a different species, since it was described from a single collection, and since at least some orange has been observed in other species. We need the type sequence. Boletopsis watlingii UK (=B. perplexa UK) - has been sequenced from northern BC, but not yet from the PNW.
