I have decided to create a post that focuses on a different mushroom species each month. Welcome to the first Mushroom of the Month! For January, let’s take a close look at Agaricus augustus, also known as The Prince.
Agaricus augustus, is a huge, HUGE! edible mushroom that can be identified by its fragrant almond extract or anise smell. It has pink-brown gills that darken with age, a ring around the stalk, and brown scales that cover the cap. This species can be found on the west coast of North America in late summer, early fall, after periods of heavy fog. It prefers to grow under conifers. I used to find these in parking lots where I used to work in California. The massive size is so impressive!
Cap: convex, becoming flat with age. 2-12.5 inches in diameter. Light yellow-white, covered with brown scales.
Hymenium: crowded gills that are free from the stipe. Pinkish brown, becoming dark chocolate brown with age.
Stipe: straight or slightly tapered up. 4-14.5 inches tall. Has a ring with a long white skirt. Smooth above the ring, but covered in brown scales below the ring.
Spore Print: dark brown
Ecology: A. augustus is saprotrophic, getting its nutrients by breaking down decaying organic matter.
