Agaricus californicus, commonly known as the mock meadow mushroom,[2] or California agaricus, is a poisonous mushroom in the section Xanthodermati of the genus Agaricus.[3]
It is mildly
Description
The caps are 5–12 cm (2.0–4.7 in) wide, white, sometimes with a grayish-tan center, dry, and either unchanged or yellowing slightly when bruised.[5] The stalk is 3–10 cm (1.2–3.9 in) long and 1–2 wide, perhaps larger at the base.[5] The spores are brown and smooth.[5]
Differentiating A. californicus
Agaricus californicus is similar in general appearance to many other Agaricus species, especially to A. arvensis,[5] A. bisporus, A. campestris,[5] A. cupreobrunneus, and which are commonly collected for the table. Since A. californicus is toxic, differentiating it from other similar mushrooms is important.
Agaricus californicus – like many other Agaricus species of the section Xanthodermati – displays a yellowing reaction where its flesh has been damaged. Unlike A. xanthodermus[5] (a close relative in the section Xanthodermati), A. californicus's yellowing reaction is not always readily apparent and the annulus is smaller. Even in specimens where the reaction is not immediately apparent the addition of a basic solution such as NaOH or even Lysol will cause the reaction to become quite noticeable, making this a convenient way to distinguish between A. californicus and similar mushrooms.[3]
