Cf. cirrhata, cookei, tuberosa? Did not check for sclerotia.
Within drip line of Pacific Madrone (Arbutus menziesii), and the trunk is about 12 in. diam. breast height and 20 feet away. Nearest Douglas-fir (Pseudotsuga menziesii) about 30 feet away. Nearest Oregon White Oak (Quercus garryana) 50 feet, and that tree is being suppressed. MF54878
On "needles" of Calocedrus decurrens. Gregarious habit and color should rule out potential of C. enterochroma which may be found on C. decurrens.
Unburned oak side, but on burned stump so probably just inside the burn perimeter
On soil burnt by the Look out Fire (Sept-Oct 2023). Fire severity medium (yellow on map). Fire site 2.
Fewer than a dozen plants in the NE portion of lot. I think @peterzika found this pop years ago.
WEW019 Was collected by Bitty Roy and Keyyana Blount on Feb 3, 2015 at Big Spires Prairie, which is a restored native prairie near Fern Ridge Reservoir, Lane County, Oregon. The fungus is terrestrial and grass associated; the grass present was Festuca roemeri (native). This prairie had been burned a few months earlier, in the fall of 2014. No trees were nearby.
Chemical aroma, with Doug-fir/hemlock/Sitka spruce
Seems likely to be a mold on a mushroom, but not squishy/obviously decomposing. Could be a truffle, but no particular aroma.
Found by truffle dog Rye. Very strong raw horseradish scent. This specimen was found underground, but very close to another above ground fungus growing on the host bigleaf maple’s base, which looked to be a more mature version and had no odor. See last picture for comparison. This forest burned in 2020.
DNA 77 (tissue from white portion of fungus) and DNA 78 (tissue from black portion of fungus)
Widespread on decaying conifer log. Unburned forest.
Burn site, on soil
milk white, mild to taste; Mushroom in Larix bog
Odor mixed, sometimes earl grey tea and sometimes fetid. In trailhead parking area under fir.
Little Pyro’s first truffle find at nine weeks! We were trying to train him on another Hysterangium that Rye had just found and Pyro found one we had completely missed instead.
Found by truffle dog Rye, fruiting gregariously along an ephemeral creek bed. Some were visible without any digging (see the bright truffle in the creek photo).
Aroma predominantly of banana/starchy tropical fruit, with undertones of Kalamata olive. Fruit bodies dense, with rainbow tones in both the gleba and peridium including orange/yellow, pink, and purple.
Surrounding trees included mountain hemlock and firs. Elevation ~5500’. Notably, these were found a couple days after the first rains of summer/early fall.

H J Andrews Expermental Forest
Clear
Temp: 36°
Mixed Douglas Fir and Maple
Cap is slimy
Stem is dry, scaly with notable rhizomorphs at base
Spore deposit: brown
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.
Enveloped in light pink-ish felty mat. Odor somewhat onion-y. Tiny hydrophobic spores
In packed, dry soil
Found by truffle dog Rye
Under Q. garryana, unburned. Found by truffle dog Rye, growing gregariously. Extra mature specimen dissolved into goo, but the other one was firm. No obvious discoloration of the peridium with handling. Odor odd, bad on the gooey specimen but not as offensive on the younger one.
Found by truffle dog Rye
Most mature specimen smelled almost cyanide/almond
Intense yellowing of cut surface over a period of a few minutes.
Found by truffle dog Rye
Microscopy by Jonathan Frank. Mounted in Melzer's
Found by truffle dog Rye
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

On Gaultheria, always causing circular leaf spots which later excise themselves from the the leaf and fall to the ground.
on sedges in marshy peatland. same species as https://www.inaturalist.org/observations/84266149
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!
UV light
Mixed chaparral, under scrub oak. Cap deep blue-black, velvety. Stipe lighter, smooth.
Found by truffle dog Rye in mixed age Oregon white oak woodland. The pictures show what is actually one specimen, it broke apart when Rye dug it up and looks like it was made up of several distinct lobes. Some parts more aromatic than others, overall it had a pleasant aroma which varied from sweet and fruity to umami spices. It does seem to have a peridium.
This was the only specimen that Rye found in an area that otherwise had (likely) one Tuber species that was relatively abundant.
Very viscid cap and stem. Rusty spore print. Under western hemlock & cedar. AJG10/29/21-34
Growing on recently fallen Pacific yew tree. Unburned forest.
