UV365 negative.

Cap very viscid

Cf. cirrhata, cookei, tuberosa? Did not check for sclerotia.

substrate: Western Redcedar needle

growing on a Clavulina coralloides

On "needles" of Calocedrus decurrens. Gregarious habit and color should rule out potential of C. enterochroma which may be found on C. decurrens.

On decomposing oak

Fewer than a dozen plants in the NE portion of lot. I think @peterzika found this pop years ago.

Under gray pine, aroma very faint

With joey

Seems likely to be a mold on a mushroom, but not squishy/obviously decomposing. Could be a truffle, but no particular aroma.

Initially found by a squirrel, many nearby digs suggests it was fruiting in numbers. Under an oak on the UO campus. Smells like Tuber lauryi to me, truffle like with notes of tomato.

Peridium dark, nearly black on one

Found by truffle dog Rye under oaks with a Douglas-fir sapling nearby. Unburned side. Little aroma to my nose, somewhat like fragrant soap.

Found by truffle dog Rye near snowmelt. Yeasty/beer aroma

Found on a dead, heavily burled tree (likely a bur oak) in a low-lying, forested area.

In Oregon white oak woodland, found by truffle dog Rye. Just under the leaf litter/think organic layer. Sweet, pleasant smell somewhat like a mild white truffle. Collected.

Love these!
