Australian Agaricus Fungi
The Agaricus genus of mushrooms include the common field mushroom & swiss brown.
Their gills stain dark brown with their dark brown spores. The gills are free from the stem which clean breaks from the fungi cap. The stems of Agaricus fungi have a distinct ring, are white or cream and are quite fibrous but vary in fragility. The skin can be white and smooth, wine coloured, pink or brown with small scales. It slightly overhangs the edge and is easily peeled right to the centre.
Most Agaricus fungi are edible but the edibility of some Australian species is unknown. FungiOz app includes several unidentified species.
It is very easy to mistake the poisonous yellow stainer, Agaricus Xanthodermis for an edible field mushroom. Click here for a detailed comparison between the yellow stainer and edible look-alikes.
