HAY-F-006498
Habitat = small shrumps (4) occurring just above a large debris pile from some young trees that have all fallen in one area. One truffle had mold growing on it and grubs eating it. The other three were solid, no mold.
Scent when fresh = grape soda on a pan fried steak sitting on a rubber mat in the sun.
No UVF observed
Microscopy (2023.10.01)
Spores - round, rough with thick wall, ~up to 32.5 um in diameter, brown
Asci - 8 spores, 250 x 33 um,
paraphyse - swollen tips. 110 x 12 um
tissue was tough. Attempted water mounting, but everything was bound so tight I couldn't see individual structures. KOH mounting and then squishing allowed me to separate asci and paraphyses

Half buried; under nut tree; edge of creek. Five units. Thick exoperidium and inside is marbled and with chambers. Fine pyramids on exoperidium. Smells of something edible. 1.2 -1.5 cm in diameter. They were connected to roots and with soil attached to them. Spores: round and ornamented: 24-49 um in diameter. Capillitium thin: 1.2-2.4 um. Second photo in situ and first photo after being cleaned. Park.

Hypogeous, few cm under the ground, attacked by Tolypocladium ophioglossoides and connected by yellow golden threads. 1.8 cm wide. Spores matured to a brown tone and from 20.9-27 um. There was a clear capillitium with septa. At the base of a huge deciduous tree. The outside skin was woody and tough to cut. It has a nice edible fungus smell, mixed with spices. The truffle had several thin cordons on the outer surface. Ornamentation outside is made of tip but not like pyramids as I saw on another truffle. The photos 2,3 and 4 don't show the right color which is more towards yellow than orange. Last photo shows the tuber in situ with its parasites. Park.

Truffle measured about 23 mm by 25 mm and was found with snake tongues.
It was growing underground under Tsuga canadensis. The largest 2.7cm.
Spores dark brown, globose, measured
*(28.6) 29.9 - 33.1 (33.5) µm
N = 31
Me = 31.3 µm
Does anyone have an idea what this might be?

Average spore size is 24 x 10 microns. Biguttulate, smooth.
Paraphyses slightly clavate, no granular contents and branched at the base.
