Would You Draw on This Mushroom—or Drink It? Artist’s Conk in the Pacific Northwest

Have you ever walked past a large, woody mushroom growing from an old log and wondered what it was?

At first glance, this mushroom looked more like a piece of weathered wood than something living. Its upper surface was dark, firm, and marked with broad rings that seemed to record years of growth.

But when I looked underneath, I found something completely different.

The underside was pale and smooth, almost like a blank canvas.

And that is where the story becomes interesting.

A Mushroom That Looks More Like Wood Than Food

Artist’s Conk belongs to the Ganoderma applanatum group, a group of perennial bracket fungi that grow from logs, stumps, and sometimes wounded living trees.

The mushroom in my photograph was growing from an old log in the Pacific Northwest. Its upper surface was dark gray-brown, deeply zoned, and extremely hard. A pale growing edge was still visible around part of the mushroom.

Unlike soft culinary mushrooms, Artist’s Conk is far too woody and tough to slice and cook as ordinary food.

It feels more like a piece of wood than a mushroom.

The USDA Forest Service describes Artist’s Conk as a perennial, woody shelf fungus with a dull brown upper surface and a fresh white pore surface that quickly turns brown when touched. Closely related members of this group may be difficult to separate in the field, so I prefer the careful name Ganoderma applanatum group rather than claiming an exact species from appearance alone.

Why Is It Called Artist’s Conk?

The pale underside is covered with countless tiny pores.

When the fresh pore surface is lightly scratched or pressed, the touched area changes from pale cream or white to brown. This makes it possible to draw words, landscapes, animals, or detailed pictures directly onto the mushroom.

No paint or ink is needed.

The brown marks become part of the pore surface rather than simply sitting on top of it. When the conk is dried properly, an etched picture may remain visible for years.

That is how this unusual mushroom earned the name Artist’s Conk.

I find that fascinating.

A mushroom growing quietly on an old log can become a natural canvas—and the drawing does not simply wipe away.

The question is: would you draw something on it, or would you save it for tea?

Why Some People Prepare Artist’s Conk as Tea

Artist’s Conk has a long history of traditional use, but it is important to separate traditional practice from proven medical treatment.

Researchers have identified polysaccharides, triterpenoids, phenolic compounds, and other naturally occurring substances in Ganoderma applanatum. Laboratory and animal studies have reported antioxidant, anti-inflammatory, immune-related, and blood-glucose-related activity.

However, these findings do not prove that homemade Artist’s Conk tea can prevent illness, boost immunity, reduce inflammation, or control blood sugar in people.

Most Artist’s Conk research remains preclinical. A randomized human trial involving a different species, Ganoderma lucidum, did not find meaningful improvements in blood glucose or cardiovascular risk markers. This illustrates why promising laboratory findings should not be presented as established human health benefits.

For that reason, I think of Artist’s Conk as a traditional, slow-simmered herbal beverage—not as medicine or a replacement for medical care.

How I Personally Prepare Artist’s Conk Tea

Artist’s Conk becomes extremely hard after it has fully dried, so I cut it into manageable pieces before storage.

My personal preparation method is simple:

I slice the mushroom into smaller pieces, steam them once, and dry them completely. After they are fully dry, I store them in a clean, dry container.

When I want tea, I place a small piece in glass or food-safe ceramic cookware and simmer it slowly in water.

Artist’s Conk can have a bitter, earthy flavor. When I have them available, I sometimes add one or two dried jujubes or a very small amount of licorice root. Their gentle sweetness blends naturally with the bitterness of the mushroom.

When I want tea made only with Artist’s Conk, I make it very light rather than preparing a dark, concentrated decoction.

In my own routine, I generally keep it to one or two small cups rather than drinking it throughout the day. That is simply my personal practice, not an established medical dosage.

As the Korean saying reminds us, even something considered beneficial can become too much when used excessively.

My Comforting Artist’s Conk Chicken Soup

Sometimes, when I begin to feel cold and slightly shivery, I make a warm whole-chicken soup.

This is not a treatment for a cold. It is simply one of the comforting foods I enjoy when my body is asking for warmth and rest.

I simmer a whole chicken with:

• Garlic
• Fresh ginger
• Dried jujubes
• A very small amount of licorice root
• One piece of dried Artist’s Conk

Once the chicken is tender and the broth has developed a deep flavor, I remove the woody mushroom piece before serving.

I finish the soup with chopped green onion, salt, and black pepper. Sometimes I add cooked rice, and other times I add softened glass noodles.

The mushroom adds an earthy depth to the broth, while the ginger, garlic, jujube, and licorice create a warm and balanced flavor.

It is simple forest-inspired comfort food—the kind of meal that encourages me to slow down and rest.

Important Safety Notes

Artist’s Conk should never be identified from one photograph or one characteristic alone. The host tree, pore surface, bruising reaction, upper surface, interior color, spore characteristics, and possible look-alikes all matter.

Do not use an old specimen that is moldy, badly decomposed, contaminated, or heavily damaged by insects.

Research has not established a standard safe dosage for homemade Ganoderma applanatum tea. Related Ganoderma products may also interact with certain medications, including blood thinners and immunosuppressive drugs, and rare cases of liver injury have been reported with Ganoderma products. Anyone who is pregnant, breastfeeding, preparing for surgery, living with liver disease, or taking prescription medication should speak with a qualified medical professional before using medicinal mushroom preparations.

Licorice root also deserves special caution. Regular or excessive licorice consumption can raise blood pressure, lower potassium, and cause other serious effects in susceptible people. Anyone with high blood pressure, heart or kidney disease, low potassium, or relevant medication use should avoid adding licorice without medical guidance.

⚠️ Foraging Safety: Never eat or use any wild mushroom unless you are 100% certain of its identification. Avoid harvesting near roads, heavy traffic, sprayed areas, polluted locations, or anywhere contamination may be present. Harvest only from clean environments. If harvesting is not on private property, always check and follow local harvesting rules and regulations.
