Parasitizing truffle,
Growing trailside near bay laurel and redwood
Spore deposit pinkish. No distinct odor. Cap 1 - 3.7 cm across. Stipe 2 - 4.5 cm long x 2.5 - 5 mm thick, hollow. No cheilocystidia or pleurocystidia observed. Basidia clavate, 22.5 - 40 x 7.5 - 10 µm. Spores 5 - 6 sided, (6.8) 7.2 - 8.7 (9.2) x (6.7) 6.8 - 7.8 (7.9) µm, Q = 1 - 1.1 (1.3), Me = 7.9 x 7.4 µm, N = 30. Growing in grass near shore pine.
Items matching description of Entoloma hebes from reference Fungi of Switzerland: Fruits in the Fall, in forests, in moist places (this specimen found in very wet area being splashed by water). Cap 7 - 20 mm across, always has a papilla, dark brown, translucent striate when wet. Gills white when young. Stipe 3 - 6.5 cm long x 1 - 2 mm thick, slightly enlarged toward the base, longitudinally whitish fibrillose, apex white powdered, base white tomentose, base color light brown to dark brown. Odor not distinct. Cheilocystidia present, cylindrical to subcapitate 20 - 45 x 5 - 11 um, some with basal clamp connection. This specimen cheilocystidia 21 - 39 x 4.5 - 9.8 um. Spore reference 5 - 8 angled, 8.7 - 11.6 x 5.8 - 7.5um, Q 1.3 - 1.8. This specimen (N = 15) 5 - 6 angled, with knobs, 11 - 11.9 x 7.1 - 7.7, Q 1.4 - 1.69. Basidia reference 4-spored, 8.5 - 11 um wide. This specimen basidia 4-spored, 10.6 - 11.6 um wide.
Entoloma sericeum looks somewhat similar, but it’s spores have rounded angles, fruitbody is larger, and there are no cheilocystidia.
This LBM turned out to be very interesting.
Montane Entalomatoid growing in moist soil along trail edge, no overstory plants in the area.

Q = 1 - 1.1 ; Me = 41.7 × 39.6 µm ; Qe = 1.1.
Some sort of sand food, or a mushroom? They were common at the site and time.
