Edible
Agaricus subrutilescens (Kauffman) Hot. & Stuntz Cap 5-13cm across, convex; whitish; fibrillose-striate, to slightly scaly; fibers deep vinaceous brown. Gills free, crowded, narrow; whitish pink then deep brown.

It's listed in David Arora's book as being a good edible, though less meaty than most other Agaricus, which I've found to be true as well. In Oregon I find it mostly on slopes in mixed company with sword ferns & Oregon grape.
Edible
Agaricus silvicola (Vitt.) Peck. Wood Mushroom, Agaric des bois, D?nnfleischiger Anisegerling, Agarico di boschi, Slanke anijchamignon, Karcs? csiperke. Cap: 5 - 10cm across, convex, cream, readily bruising ochraceous and becoming more yellow with age. Hymenium is free ( cap is convex or flat ). Stem: 50 - 80 x 10 - 15mm, concolorous with the cap, base usually bulbous. Stipe: has a ring. Ring: large and pendulous, upper surface white, lower drab. Flesh: thin, white. Taste: mushroomy, smell of aniseed. Gills: free, pale greyish-pink at first later chocolate brown. Smell: Aniseed. Cheilocystidia numerous, thin-walled, oval to subglobose, hyaline, 10 - 20 x 7 - 20. Spore print purple-brown. Spores ellipsoid 5-6 x 3-4-. Habitat in coniferous and deciduous woods. Season autumn. Occasional. ---- The cap is light cream, and bruises yellow ochre when damaged. It is much the same colour as the cap, and has a fragile drooping ring. The flesh is thin and white, and smells of aniseed. It looks fairly similar to a young death cap, it is believed by some mycologists. ---- Agaricus silvicola grows in both deciduous and coniferous woodland in Britain, Europe, and North America. Appearing in the autumn, it is rarely seen in huge numbers, usually just a few, or solitary ( Season: August to November ). Often found in loose groups. ---- It is suspected to have caused an allergic reaction in a few people in North America. ---- Agaricus xanthodermus, the yellow stainer looks very alike but bruises chrome yellow when handled or cut and smells of Indian ink or Agaricus pilatianus which stains yellow on cutting and smells of carbolic. Both do not smell edible. People can mistake some of the Amanitas for field mushrooms but on inspection they are quite different.
Poisonous/Suspect

Habitat in mixed woodlands, mostly conifers. Found in Colorado. Season September. Edible. Comment This species does not satisfactorily fit any current American taxa but does agree very well with the European name given here, particularly in the very narrow spores.
Poisonous/Suspect
Agaricus pocillator, a woodland mushroom, is distributed through southeastern North America in ranges a minimum of as far north as Illinois. It will be distinguished within the field by its dark center, its small, bulbous base, that stains yellow, and its relatively slight stature. It's very similar to agaricus placomyces, however is a slightly smaller mushroom with a scalier cap and a more northern range among the united states. Edibility isn't certain for agaricus pocillator, however many other yellow-staining agaricus species ar poisonous. Hikers are typically warned to avoid eating it when spotted. ---- Cap: Whitish to dingy, developing vaguely concentric brown to greyish scales towards the middle. 3-10 cm; Convex to broadly convex or nearly flat in age, sometimes with an obscure, darker bump; Dry; Gills: Free from the stem; Close; White, turning into pink, then brown. Stem: With a small bulbous base that bruises yellow; with a ring that usually persists into maturity; 4 - 8 cm long; 0.5 - 1 cm. thick; Partial veil when covering the gills not developing dark droplets. Flesh: Staining bright yellow in the base; White throughout; Taste: Odor typically unpleasant, however sometimes not distinctive; Taste not distinctive or somewhat unpleasant. Spores: 4.5 - 6 x 3 - 3.8 ยต. Chem. Reacti.: Flesh and cap yellow with KOH. Ecology: They are saprobic, meaning that they survive by decomposing dead or decaying organic material. Growing alone or gregariously beneath hardwoods and in mixed woods; Saprobic; Summer and fall.

Distribution, America and Europe. ---- The beautiful Agaricus augustus is considered by many to be the most delicious of the edible Agaricus species. It is a happy find for any mushroom hunter, although it is reported to be difficult to find them before the worms do! Like other Agaricus species, the Prince grows on rich organic substrate, often as a litter decomposer in nature. It is probably a secondary decomposer, which means that bacteria and other fungi have to break down raw materials before Agaricus can grow. On a commercial scale this is the process known as composting. The Prince can have caps about one foot (30 cm) in diameter, although many mycophagists prefer to eat them when unexpanded because of their better texture and odor. The gills turn chocolaty brown when the spores are mature. However, even somewhat expanded caps can show gills that are still white. The beautiful veil and scruffy to shaggy stem (at least when young) are also hallmarks of this species.
