Shrubland/mixed hardwood conifer forest, Convict lake, 7,850 ft. Inyo National Forest
Growing from moss in a seepage on side of Convict Lake Trail
Small, rather nondescript sporocarps. Pileus umbonate, brown to grayish. Lamellae subdistant, free to narrowly attached, brownish to orange. Stipe white, finely flocculate, fragile
Smell indistinct

Growing from grassy wet meadow. Pileus tacky, golden-brown, striate, secotioid with a small amount of velar tissue attaching it to stipe. Stipe yellow, slightly scurfy. This doesn't seem to have the character of a Psilocybe, I feel like it has Bolbitius energy @warren_cardimona

Small hypogeous gasteroid basidiomata, exterior light peach color, interior light yellow, composed of convoluted hymenium. Spores ellipsoid, rugulose, with small hilar appendage, 14–16 x 10.4–11 μm; walls 1.5–2 μm thick; starting light yellow, becoming brown. Basidia 34 x 9.4 μm; mostly 2-spored.

Partially buried in soil, on shaded slope dominated by manzanita, also with Eriodictyon, Prunus, and Ribes, with Quercus cornelius-mulleri about 20 ft away.

With Arctostaphylos.

Anza Borrego

Burned Quercus/Pinus dominant woodland (now shrubland post-burn), just west of Knoxville road near Lake Berryessa
Growing in soil and directly off fine roots in a hole leftover from a burned out root system
Brown pileus with a wavy margin. Lamellae white to cream colored, anastomosing, subdistant to distant, broadly attached to subdecurrent. Stipe short, fibrous, off-center
Smell indistinct

Growing from mosses on rocks in live oak and Umbellularia forest in hillside ravine. Pileus dark blue with nearly black scurfy scales. Lamellae light bluish white, sometimes forking, narrowly attached, darkening and becoming covered in pink spores in age, UV+ bright bluish white. Stipe smoothly fibrillose, lacking cottony white base.

Growing from duff and organic matter under Ribes nevadense understory- Calocedrus decurrens, Abies and Alnus rhombifolia nearby
Near East Fork Barton Creek, San Bernardino NF
Subdecurrent gills with pale pink spore print (seen in third photo)
Farinaceous/cucumbery smell
Very bitter/chemically taste
Slightly UV reactive (hard to get photo)

Under leaf and branch litter under Quercus kelloggii, surrounded by Arbutus menziesii, Quercus agrifolia, Q. lobata or a hybrid thereof, and Pinus ponderosa, with an understory that has been badly invaded by Cytisus scoparius following a fire. Pileus dark gray, broadly convex with shallow umbo, with a single small patch of veil tissue stuck to the cap. Lamellae grayish-tan off white, free, very dark for an Amanita. Stipe ornamented with grey chevron patterning, whitish underneath. Volva conspicuously present at base, constricted midway, flaring at the mouth and tapering to a point at the base, very grey especially on the inside. No noticeable scent, UV-, KOH not sampled as only 1 specimen was present.
