The Agaricus genus of fungi provides us with some of the best tasting and prolific mushrooms of Winter. If you can learn how to identify the one bad one, you can be sure of a good feed of traditional white mushrooms.
Agaricus have large, fleshy, white caps and are, essentially, the mushrooms that you buy from your farmer’s market or supermarket.
We have three species of edible Agaricus around Gawler, two of which are described on this website. They are pretty similar and have slight differences but are all edible. There’s the Pavement Mushroom, A. bitorquis and the Button Mushroom. A. bisporus. Then there’s the slightly toxic A. xanthodermus. As long as you learn to broadly identify members of this genus and know what to look out for in a Yellow Stainer (A. xanthodermus), you’ll be right. Each of these have their own page that you can link to from below.
All of the mushrooms linked to by this page have several general features in common. There are slight variations between the species but generally, you will find –
- Broad white/brown cap
- Cuticle that is easy to peel
- Crowded gills that start pinkish and become browner with age
- Brown spore print
- Thick stem with a fragile ring that is easy to destroy
- No volva
- The stem is easily separated from the cap
Our local Agaricus species are –
TOXIC! We put this one here as a comparison so that you can differentiate it from the other Agaricus
