Shaggy Mane Mushrooms

The Shaggy Mane is very easy to identify.

Common Name: Shaggy Mane Mushroom
Other Names: Shaggy Ink Cap, Lawyer's Wig
Scientific Name: Coprinus comatus
Family: Agaricaceae (Basidiomycete fungi that grow on the ground in organic debris)

A flush of Shaggy Manes can have mushrooms at various stages of maturity.

Description: Fruiting body is tall and white with an almost cylindrical, bell-shaped cap that has "scales" which give a "shaggy" appearance. The cap has gills that are very tightly packed together, and they will quickly "melt" away into a dark black, inky liquid within a few hours of being picked. The flesh is tender and delicate. I have only ever eaten this mushroom raw. I came across a patch of Shaggy Manes at the edge of the woods while I was visiting a wildlife park in Germany. This is one of only a few mushrooms that are almost impossible to mistake, so I quickly sampled a young one... delicious!

Mushroom Niche: Decomposer
Natural Culture Medium: Chipped wood, Rich Soils, Manure

Coprinus comatus
From Our Edible Toadstools and Mushrooms and How to Distinguish Them by W. Hamilton Gibson.

  • A native to North American and European meadows and grasslands.
  • It has been introduced to Australia and New Zealand.
  • It is cultivated in China for food.

  • The gills will change from white to pink to black and then secrete a black liquid that contains the spores... this black liquid is the reason for its other name "Shaggy Inky Cap".
  • The scientific name comes from the Latin coma = hair... comatus = hairy or shaggy
  • This mushroom will "auto-digest" after it is harvested and quickly become unusable within 4-6 hours... this is why it is not seen for sale outside of rare farmer's markets in the U.S. (however, it is raised commercially for food in China).
  • The Shaggy Mane is known to kill at least two species of nematodes, one of which is harmful to plants.

General "Mushroom" Vocabulary
  • Mushroom - spore-bearing fruiting body of a fungus
  • Fruiting-body - what is commonly called a "mushroom"... the spore-bearing reproductive structure of a fungus
  • Hyphae - vegetative part of the fungus... will develop a fruiting body to reproduce
  • Mycelium (mycelia is plural) - a mass of hyphae is
  • Spawn - material that contains actively growing hyphae of the fungus. Spawn can be used to inoculate the desired culture substrate (logs, branches, stumps, sawdust, etc.) for people to produce a crop of fruiting bodies/mushrooms
  • Stipe - the stem/stalk of the fruiting body/mushroom
  • Pileus - the cap or cap-like structure on top of the stem that supports the spore bearing surface
  • Lamella - the gills (aka ribs) on the undersurface of some fruiting bodies/mushrooms
  • Pores - spongy material with "holes" in it on the undersurface of some fruiting bodies/mushrooms... some mushrooms have these instead of gills

Here's the recipe:
Primary Uses:
  • Fresh eating (in small amounts)
  • Cooked - best steamed, or added to sauces or soups. Its high water content make it difficult for sauteing, but some insist this is the only way to prepare it. Battered and fried.
  • Dried

Secondary Uses:
  • Traditionally used as an ink
  • Used as a dye 
Shaggy Mane on left is perfect for harvest.
Shaggy Mane in center is too mature for harvest as it is dripping "ink".
Shaggy Manes on right are almost gone.
Harvesting: Usually just one flush in the Fall, but occasionally can flush in the Spring and/or Summer depending on your locale. Harvest daily, and be ready to use almost immediately for best results. Look for mushrooms that are firm, plump, clean, and with caps closed or just barely opened. Those that are already very open or just black rings on stalks should be avoided unless you are making a black-colored meal.

Wild Harvest: NOTE: BE VERY SURE OF THE MUSHROOM YOU HARVEST FROM THE WILD! From Spring through Autumn in areas of recent disturbance after a rain. They are often seen along roadside ditches, gravel patches, or soil with lots of organic matter. Due to dirty run off from roads, mushrooms growing near frequently travelled roads are best avoided.
Storage: Best used within 4-6 hours of harvest as this mushroom will quickly deteriorate. If the mushroom is cooked, it can store in the refrigerator for a few days. Another method to store fresh the Shaggy Mane is to place it immediately in a jar of water, then put this in the refrigerator. It is thought that the absence of oxygenated air slows the deterioration. Alternatively, after it is cooked, it can be frozen.

Cultivation Substrate: Can grow on just about any rich, composted, organic matter.

Cultivation Details: There are Shaggy Mane outdoor mushroom patch spawn available for purchase. Just mix the spawn into a soil bed or compost pile, water, and wait. There are many, many "home remedies" to get Shaggy Manes to grow in new locations. When I try some and have success, I'll write about it.

Spawn Available: Many forms available from test tubes, to petri dishes, to bags... all ready to be mixed or buried in substrate.

Incubation of Logs: If soil/compost with spawn is prepared in the Spring, they typically there will be Shaggy Manes ready to harvest in the following Autumn.

A Shaggy Mane that is probably a little too mature to harvest for food.

Fruiting Temperature: Typically needs cooler weather, but local varieties can have different tolerances from location to location.

Induction of Fruiting: Typically needs sustained moisture for a few days before fruiting begins.

Life Span: No reliable information that I can find. It seems that if you do not harvest all the mushrooms in one location, and the location maintains its high organic content, then there should be yearly, seasonal flushes almost indefinitely.

Shaggy Manes can produce large flushes like this one seen above.

  • Some people who eat any mushrooms from this family may have a bad reaction if they drink alcohol while eating this mushroom. It is kind of like nature's anti-alcohol food. One person eating the dish can have a fairly significant, non-deadly reaction that lasts a few hours and then passes, while another person eating the same dish and drinking the same amount has no reaction... very interesting!
  • If you have gout or kidney disease, you may want to avoid eating a lot of mushrooms since they contain concentrated levels of purines.


  1. I really like the taste of this kind of shrooms. I used to eat a lot of it back in my youthful days.

  2. I ate them a lot when I was a kid. My parents would sauté them in butter, garlic and salt n pepper. I just found a bunch on my neighbour front yard this fall. So I cooked up a batch and they are ohh so tasty.

  3. Is there any reason to use these instead of Agaricus bisporus or some kind of oyster mushroom?

  5. As far as eating goes, the oyster and shaggy mane both taste great. Much better then the white mushroom

    I just had some of these lovely comatus. I gently rinsed a few off,(about a half pound) placed them in a two inch tall stainless steel frying pan, one half cup water, two tablespoons butter, dash of salt, sprinkle of marjoram, a dash of clove powder, 2 ounces cream. Cooked them till about half original size at low temp, poured all over 3 slices toasted whole wheat bread... Absolutely delicious.
