Herbarium specimen reported

Notes: Location accurate to about 200 meters (600 feet) could not get a GPS reading any closer to the location because of the trees blocking view of Satellites I guess.

Gastroboletus turbinatus – confirmed id

Hi Johann,

I ran across this collection in the backlog at my lab.

Matt does not usually do much identifications so best to send things to me in the furture for a more timely response.

The spores are not trucate and measure about 16.5-17.5 × 7 microns. It keys out nicely to G. turbinatus

the bluing reaction is dependent on age of specimen and local environmental conditions the fact that there was some bluing is important

I have assigned herbarium number 35959 to it for further reference.

The location of the collection makes it very desirable. thanks for sending it in.

I think Matt Trappe is currently living near Philomath, Benton Co., OR. Other than the address for mailing material to him, I have no contact info. Sometimes it takes several months to get an ID. And if this does happen to be a new species, he may be waiting for James Trappe to take a look. Be patient.

what should I do?

This looks like a new one, at least to my uneducated eye.

Okay I will do that

But I would suggest mailing it to Matt Trappe, c/o Forestry Sciences Lab, Oregon State University. This is so rarely seen, along with Gastroboletus rubra, that it will become an important addition to the herbarium collection. Matt’s complete address can be found at NATS.org

i sure did!

Hope you collected this.

Looks like one of the rarer Gastroboletus or Gastrosuillus species. Without an actual collection, cannot be certain. Not enough bluing of cut surface to be G. turbinatus in my opinion. Would have expected much more reddening on G. rubra. If I had to guess, I’d suggest Gastroboletus subalpinus: but I have never seen that species, and have only read about it.
