CA, Southern California, 20071015
Madison Heights, two mushrooms. 

Spores, at 1000x, IKI stain.  Partial-reiculation is clear. Spores, at 1000x.  Note how poorly visible the ornamentation is without an iodine stain. Spore print of Russula pectinatoides (left) and Lactarius alnicola (right) side-by-side. Spore print.  Yes, that really is about what it looks like against white paper. Sliced in half. Knocked over. Contorted cap, top view. 

Russula pectinatoides [] 

Lawn, W side of Oakland, past first drive going S from Fillmore, between sidewalk and road, under oak? 
 GEN medium mushroom, scattered in lawn, mild odor, no taste to mildly acrid in age
 ST ~30x15mm, straight, solid, firm like cap, smooth, white, brittle
 CAP 70-90mm, contorted and convex, smooth, pale yellowish to brownish, darker in center
 FLESH white, Russula-textured, firm, unchanging
 GILL whitish, brittle, somewhat close
 SPORE print white to sl creamy, round to sl ellip, low amyloid spines and some short ridges, 6.3-7.9x5.6-6.6um
Hard to find info on Russula on the web.  Stressing the pure white, unchanging stalk and flesh, and non-acrid taste, I come up with R. brevipes from the key in Arora.  Darvin suggests R. pectinatoides. Tasting it the following day (and not immediately after tasting the Lactarius below!) it does have a mildly acrid taste.

Spores, at 1000x, IKI stain.  Reticulation is clear. Spores, at 1000x, IKI stain.  Reticulation is clear. Spore print of Russula pectinatoides (left) and Lactarius alnicola (right) side-by-side. Spore print.  Color is fairly accurate. Sliced in half.  Yellowish stain just barely visible along stem. Close-up of gills. Nice ones, top and gills. Scattering in a lawn. 

Lactarius alnicola [] 

Lawn, S side of Arden, halfway E of El Molina, lawn under big oak, large fruiting. 
 GEN large mushroom, scattered densely in lawn, under oak, v acrid taste
 ST ~30x15mm, tapered, cap-colored, darker below, hollow, bleeding white a little bit (aging yellowish), brittle
 CAP 80-100mm wide, plane to depressed, light golden-brown, faintly zoned but no detectable fibrils or scales even at 30x (must be there but dissolved in rain?)
 FLESH white, Russula-textured, staining faintly and v slowly yellowish, firm
 GILL cap-colored to almost orangish, white beads but hard to get it to bleed when cut, fairly close, shallow (3mm deep)
 SPORE print v pale orangish, round, low amyloid reticulate ridges, 6.9-8.9x5.9-7.6um
Arora only gets as far as the group, as usual. Sources on web suggest L. alnicola itself as the common one under live oak in California.

Agaricus bernardii [] 

E side of Hudson not far N of Arden, in lawn.  Set of old ones.  Checked for this much-vaunted briny/iodine odor.  I just barely could convince myself it was a bit briny, but if that's it, I would hardly go around stressing it as one of the critical discriminants!  The more useful feature appears to be pinkish blush in cracks and divots taken out of the cap.

Boletus subtomentosus [] 

NW corner of Hudson and Arden, in lawn.  Several scattered, almost hidden in grass.

Chlorophyllum molybdites [] 

Beautiful set on N side of Arden not far W of Oak Knoll.  In grass between sidewalk and road.

Pisolithus arrhizus [] 

Several scattered in leaves at base of coast live oak on W side of Lake in that island park thingy N or Arden.

Psathyrella candolleana [] 

A few faded ones (fibrils still visible though) scattered in lawn on S side of Arden, not far W of Oak Knoll.

Group of young puffballs. 

puffball 

Clump of young ones at base of E-most oak on N side of Fillmore just W of Los Robles. 
 GEN small puffball
 CAP smooth, round, white, rooted
 FLESH white and somewhat soft when young, waiting for it to mature
 SPORE immature

Slice in half.  Well, maybe \Bottom view. Top view. Spores, at 1000x. Nice old one, just ruptured. 

Bovista pila [] 

Old one by first driveway on N side of Fillmore going E from Los Robles.
 GEN medium puffball
 CAP relatively smooth, mottled brownish, round, ~60mm wide, base obtuse but not sterile, skin v thin, rupturing irregularly at top, apparently no root (was free of the ground when I found it)
 FLESH no structure visible
spore mass medium ochre brown, powdery, soft
 SPORE brown, smooth, ellip to tear-drop, apic, no texture visible inside, 4.9-6.5x3.6-4.3um
