Observation 13431: Leccinum Gray

When: 2008-11-01

Collection location: near Cape Lookout, Tillamook Co., Oregon, USA [Click for map]

Who: Daniel B. Wheeler (Tuberale)

No specimen available

This specimen does not match anything I have a reference to. Specimen is fairly large, 7 inches tall, nearly 3 inches across the base of the stipe, which is white with dark gray-black scabrums, except near the cap, where they are a lighter tan colored. Pores are nearly concolorous with the cap, which is very dark reddish brown. Stipe become pointed near the base (not shown in photos), widening quickly to reach about 3 inches near the soil surface, then slightly enlarging to 3.25 inches about 1 inch from ground level, then quickly narrowing to the cap attachment, which is only 1.5 inches. Very pleasant odor. Cap is a much darker color. Stalk alone is near L. aurantiacum. Cap alone is near L. manzanitae (at least one collected identified as such at M.O.). Cap color matching nothing that I can find.

No record found for L. largentii in OR

But that was just an initial search on the web.

staining can be subtle or absent; is there a prior record for largentii in OR?

Same plant

It is a manzanita! Same genus. Bearberry or kinnikinnick is Arctostaphylos uva-ursi and it grows in the sand dunes in CA where L. largentii is found. In fact, the mushroom is in the middle of it every time I have found it.

Bear berry?

There is a bearberry that grows readily in Oregon (and into Alaska) called Uva ursa, which is also called bear berry or kinnicinnick. Manzanita is a completely different shrub here in Oregon, and there are several species, the most common being Hairy manzanita, for which the town just north of Tillamook (Manzanita) is noted. Which of these shrubs are you speaking of? There was kinnikinick near where this specimen was found, where it often colonizes sand dunes. But manzanita is usually an understory of established forests on the Oregon coast.

No red staining, either.

No reddish stains or even pinkish stains on the cut portions of the stipe. I haven’t sliced the mushroom for drying yet, but the base has not stained any color: looks pure white at this time. I just checked the specimen again (to be certain) and to my eye there is a very slight bluing at the very bottom of the stipe. But that color could also be from a contamination (lots of moss on the base of this). Unless I was specifically looking for it, it would probably be overlooked. Bluing area less than 3mm across.

Sorry about this, but I thought I was going to have a nice omelet of this – before it became something I couldn’t identify. I already sliced off the bottom of the stipe for ease of transportation, and to keep my other collections dirt-free. I still have the fungus, and will be drying it shortly. It still looks nice, and has a very pleasant aroma.(sigh)

thanks Darv…funny how those mistakes get passed along…

You can correct your books for L. largentii.
I’ve collected a hundred of them from the holotype location.
It fruits with beach pine (Pinus contorta) and manzanita (bear berry).
Bessette copied the error in Thiers.
The toyon was actually a silk tassel !

i think Darv is onto something here…

largentii has been reported only from CA, but quite far North (Eureka) so it is not inconceivable that it grows in OR. Save it!!!

description from “North American Boletes” by the Bessettes:

pores described as buff-olive when young. scabers brown, turning black and forming a reticulum in age. stipe base context staining reddish or blue.

cap dry or subviscid (as opposed to viscid in L. manzanitae); cap context slowing staining fuscous.
grows w/toyon, madrone and manzanita.

If the stalk bruised bluish, it could be L. largentii.
