Shrubland/mixed hardwood conifer forest. Convict lake, 7,850 ft. Inyo National Forest
Growing from sandy soils in a zone saturated from snow melt creeks with Betula occidentalis, Populus tremuloides and Populus trichocarpa in a moist area on the Southwest side of lake
Large, fleshy mushrooms with a brown to silvery, finely tomentose pileus with striate margins. Lamellae close, dark brown, narrowly attached. Stipe white at apex becoming darker near base, equal, fibrous
Smell musky
Taste slightly salty, musty, like portobello
KOH yellowish on stipe, slightly blue green on cap
Stipe fluoresces bright green/blue

Red staining on stipe. Cheilocystidia 108 - 163 (200) x 17.5 - 22.5 µm, wall thickness up to 6.3 µm. Spores (13.5) 16.6 - 21 (22.9) x (5.6) 6 - 7.2 (7.6) µm, Q = (2.3) 2.6 - 3.2 (3.4), N = 41, Me = 19 x 6.6 µm, Qe = 2.9. Growing near what I believe is Suillus pseudobrevipes (see last image).

Collection and photo and notes by Buck McAdoo.

Caps - 1 1/2 - 2 cm wide, convex to almost plane, deep straw-yellow with orange fibrils. Context dull watery yellow.
Gills - Adnate, lamellulae present, yellow. Possibly bruising orange slowly when touched.
Stipe - Up to 2 cm long and 3 mm thick. Equal, White at apex then buff below and staining slowly yellowish when handled.
Odor & Taste - Mild.
Spore deposit - Unobtainable.
Habitat - Solitary to scattered on rotten conifer logs near Tomyhoi Lake on September 18, 1990.

Big Lagoon County Park Permit. Caps slightly viscid (wet from rain). Scent indistinct. Pics 3 and 4 show UV and no UV. The UV was a somewhat subtle purple glow irl, was not picked up very well by the camera.

Found in an Eucalyptus globulus dominant urban forest on the edge of a golf course in the Presidio, Golden Gate National Recreation Area
Growing on mixed substrates (woody material and dead grasses) under Eucalyptus globulus
Pileus bight red/orange, appearing slightly velutinous. Lamellae white, subdistant to distant, broadly to narrowly attached. Stipe elongate, white and opaque at apex, becoming tomentose and brown at base

Cellular features:
Hyphae dimitic; 'type 1' is hyaline, 6 µm thick (walls 0.8 µm), agglutinating into thicker hyphal yarns 35 µm thick, which weave together forming the primary mass of the carpophore; 'type 2' is brown, 5 µm thick (walls 1 µm), occurs only on cap surface, and produces setae.
Cap setae 20 - 40 µm long; hymenial setae lacking. Cystidia lacking.

Spores:
Elliptical, smooth, light brown, thick-walled (0.8 µm);
(6.3) 6.8 - 7.6 (7.9) × (4.3) 4.4 - 5.7 (5.9) µm
Q = (1.2) 1.3 - 1.6 (1.7) ; N = 30
Me = 7.2 × 5.1 µm ; Qe = 1.4.

Small truffle with light brown to creamy white exterior,
Soft, spongey, creamy gleba,
White UV to yellow UV,
No odor/taste,
Growing above soil at base of doug fir next to trail,
Near sitka spruce/redwood,
Spores are white, subspherical with echinate ornamentation and amyloid

Maybe Tuber gibbosum?
Light brown to creamy peridium,
Dark brown to purple, firm, marbled gleba
Indistinct odor,
Yellow UV on exterior; yellow green UV on cut interior,
Mild cleaner taste,
Found off trail under log near Doug fir/sitka spruce,
S, Elevation 30ft.,
Honeycomb-reticulate spores

Very slimy/sticky cap. Very delicate, stipes start to buckle under the weight of the cap with the slightest disturbance. A few were yellow but most were whitish beige, color seems not necessarily correlated to maturity.
