September's Mushroom of the Month
augustus: the Prince
The prince is a large yellowish brown mushroom with
yellowish brown scales on the cap.
It is an excellent edible.
Of all the edible Agaricus mushrooms I have
tasted this is my favorite. The flavor of young
specimens especially, is mushroomy with sweet, almond
This may not be a native species in Michigan; the
specimens we find are often on mulch and may be coming
in from the Western United States.
Reputedly there is a smaller Eastern version.
The concave to flat cap with yellowish brown scales over
a pallid base range from 4 to 10 inches (10 to 25 cm.)
caps of button specimens often have a flattened top and
are somewhat squared off like marshmallows.
The caps stain yellow with bruising.
The equal to slightly bulbish, whitish stem that
often bruises or ages yellow ranges from 3 to 6 inches
(7.5 to 9 cm.) long and ½ to 1 ¼ inches (1.25 to 3.125
The tough, fibrous, skirt-like ring sometimes has white
to brownish patches on the underside.
The free gills are white, very slowly changing to
grayish brown or pink, and then quickly to dark brown to
blackish brown as the spores develop.
The thick, firm flesh is white.
The odor and taste are pleasant, reminiscent of
almonds or almond extract.
The spore print is dark brown. Agaricus augustus
is found in grassy areas, especially near disturbed
ground like paths, road edges, woodland clearings.
It occurs singly or in small groups.
In Michigan it fruits from July through early
have found this mushroom growing in wood chips and along
paths in suburban parks.
There are no close look-alikes.
With the somewhat sweet almond-like flavor, young button
mushrooms are excellent when sautéed in butter.
The large size of these mushrooms and the flavor
makes them good candidates for stuffing.
Like almost all edible Agaricus species they are
quite versatile and can be used in all sorts of mushroom
When the mushrooms are large and mature, I will scrape
off the chocolate brown gills before cooking.
