Maybe T.californicum?
White to tan, medium-sized with furrowed peridium,
Solid gleba, marbled with white veins,
White UV on cracked exterior and cut interior,
Odor is like a mixture of rubber and cleaner, an odor reminiscent of a garage; I smelled it again hours later and it was cheesy,
Tastes like cleaner,
Indistinct KOH,
Growing trailside near Doug fir/red alder/coast redwood,
NE, Elevation 252 ft.
Thick walled, globose spores within ascus

last three spore microcscopy images were mounted with 5% KOH -- showing interesting wavy "spine" ornamentation -- reminiscent of previously observed relative: https://www.inaturalist.org/observations/18266184

Omphalina "rivulicola-CA01" Nanopore data for this observation will be populated here within weeks, from the same immediate locality as this observation with ITS data: https://www.inaturalist.org/observations/199147140

About a dozen small white growths or conidia were observed on the roots of a uprooted tree. The larvae host was fully buried in the soil. The larvae were all oriented the same way with the fungi producing conidia out of the head. The larvae are also in a casing indicating they were going into pupation. Conidia are fusiform and very small. They were hard to get a good photo of. Mycroscopy photos at 1000x

In soil near burned cottonwoods.

Exciple smooth, whitish; epihymenium pruplish, subhymenium white.

Asci 267–287 x 12.5–15 µm; IKI+ amyloid with distinct ring, and weak reaction on wall, only intense at top. Ascus base like fish tail fin.
Paraphyses simple, cylindrical, 3.3 µm thick, equal; clavate end 4.3 µm thick, not crooked.
Subhymenium textura prismatica.
Ascospores hyaline smooth, biguttulate, [13.6] 14–15.5 [16.8] x [7.5] 8.2–9 [9.5] µm (mean 14.7 x 8.7 µm); Q 1.4–1.8 (mean 1.7); larger than G. violacea s. str. (“12,5-14 (-14,5) × 7,8-8,5 μm”).
