Finding the fun in foraging for fungi
On July 7, while walking a trail in Goffstown, mushroom forager Christine Gagnon shared with me her No. 1 piece of advice for foraging beginners.
“Don’t eat anything until you can identify it yourself. [Not] until you’re 100 percent sure,” she said. “The only way to know if a mushroom is safe to eat is if you have learned to 100 percent, confidently, identify that mushroom on your own and you’ve researched edibility. … The only rule is to know your mushrooms before you eat them.”
With about 30,000 different species of mushrooms in New Hampshire, according to Gagnon, it’s no wonder that more and more Granite Staters are joining in on mushroom hobbies from observing, foraging and collecting, to cooking, eating and making dye.
“The interesting thing about the Northeast in general is that I think we have a greater variety of species than a lot of other parts [of the country], or at least the east in general,” she said. “So that kind of makes it exciting.”

Mushroom season
Gagnon founded Uncanoonuc Foraging Co. in 2021. She led me through our walk much like she would lead her foraging classes on local trails where she looks for mushrooms and talks about the different characteristics that can help people identify them. It turns out, the rain and humidity we got in July made for perfect mushroom weather. Gagnon had returned to New Hampshire from California the day before, and told me how she couldn’t wait to get back.
“I saw here that it was exploding [with] mushrooms with all the rain and suddenly, of course, [they] decided to show themselves while I was on the other side of the country,” she said. “I got back yesterday morning … and [by] noon I was in the truck … to go look for mushrooms.”
According to Gagnon, as long as they have adequate rain and moisture, mushrooms can be found and foraged anywhere, from your lawn with full sun exposure, to a shady spot in the woods under a tree.
She says August through October, ending around November, is generally the ideal time for mushroom foraging, but each mushroom has its own season, with morels popping up the earliest, usually any time between April and June.
Corey Fletcher, owner and chef at Revival Kitchen & Bar in Concord, who often cooks with mushrooms, adds that chanterelle season is typically in July and August, chicken of the woods around August and September, and hen of the woods in September and October. The seasons all depend on having the ideal weather conditions.
“A lot of times it’s related to rain,” Gagnon said. “If we have a really dry summer, we’re not going to see a lot of mushrooms until the fall when it starts to get wet again.”
Gagnon administers several groups on social media where she helps people identify mushrooms, and speaks at events where she educates people about mushrooms’ role in the ecosystem and planet.
During our walk, she told me how her fascination for mushrooms sprouted when she was in elementary school while living on her grandparents’ farm in Quebec.
“Down the road there was a log cabin in the woods that a Scandinavian family lived in and they foraged for mushrooms,” she said. “I remember going in and they had all these mushrooms on the table … and I became immediately fascinated. Even though I never did anything with mushrooms for years, that image always stuck in my head.”
Her obsession was reignited about five years ago when hiking the Uncanoonuc Mountains with her family.
“I saw the most bizarre mushroom I had ever seen at the time on the side of a tree. … I got it identified as a Hericium americanum, which is bear’s head tooth, … so that’s when I became obsessed again.”
What are mushrooms?
During our forage, Gagnon and I came across Monotropa uniflora, a plant that is often mistaken for a mushroom. While not a mushroom itself, it does rely on mushrooms to grow.
“It [doesn’t have] chlorophyll, so it can’t convert heat to energy [or] photosynthesize,” Gagnon said. “So it parasitizes the mycelium from the ground to get what it needs to grow.”
Mycelium is the organism for which mushrooms are the reproductive body. The mushrooms emit spores to propagate the organism.
As Eric Milligan puts it, the fruit body we pick, the mushroom, is like the apple on a tree. Milligan is the manager of New Hampshire Mushroom Co. in Tamworth, through which he leads forages and identification sessions. While existing underground, mycelium has a white, cotton-like appearance that he says can be found in the woods underneath logs. According to Milligan, the role of mycelium in ecosystems is critical.
“You could say mycelium is sort of like Mother Nature’s internet,” he said. “If we had four pictures next to each other of mycelium underground, … a picture of the internet and how that sends out information, a picture of the human brain and how that sends out electrical impulses and then a picture of the universe, all four pictures are exactly the same. How they operate are exactly the same.”
Mushrooms, he says, keep ecosystems all over the planet balanced, mycelium being an agent for bioremediation, the process through which biological organisms break down pollutants. He notes that mushrooms have been used to clean up oil spills, a species exists that blocks radiation, and some could potentially be used to digest plastic by turning petroleum-based hydrocarbons into biodegradable hydrocarbons.
“There isn’t an aspect of our lives right now that fungi could not benefit,” Milligan said.
Mushroom Turnovers
6-8 servings. 30 minutes.
1 sheet of puff pastry, thawed according to the package instructions
8 ounces black pearl oyster mushrooms, roughly chopped
1 Tablespoon butter
1 shallot, finely chopped
2 cloves garlic, minced
1 Tablespoon fresh thyme leaves
Salt and pepper to taste
2 Tablespoons truffle oil
3 Tablespoons balsamic glaze
¼ cup grated Parmesan cheese
1 egg, beaten (for egg wash)
Preheat your oven to the temperature indicated on the puff pastry package instructions.
Add the oyster mushrooms to the skillet and cook for about 5 to 7 minutes, stirring occasionally, until they are tender and lightly browned. Season with salt, pepper, and fresh thyme leaves. Cook for an additional 2 to 3 minutes to allow the flavors to meld together. Remove the skillet from the heat and let the mushroom mixture cool slightly.
In a skillet, heat the olive oil over medium heat. Add the chopped onion and minced garlic, and sauté until the onion becomes translucent and the garlic is fragrant.
On a lightly floured surface, unfold the thawed puff pastry sheet. Roll it out slightly to smooth the creases and create an even thickness. Cut the puff pastry sheet into squares or rectangles of your desired size.
Drizzle a little truffle oil and balsamic glaze over a baking sheet lined with parchment paper and sprinkle grated Parmesan cheese on top. Place a spoonful of the mushroom mixture a few inches apart.
Bake the mushroom puff pastries in the preheated oven according to the package instructions for the puff pastry, usually around 15 to 20 minutes, or until they turn golden brown and flaky.
Once baked, remove the puff pastries from the oven and let them cool slightly before serving.

Identifying
When you spot a mushroom, you will notice many characteristics, such as its size, the color of the stem, its cap, gills, and spores, and the location where it is found. Some mushrooms even have distinct scents, like candy caps, which Gagnon says smell like burned sugar or maple syrup. There are various factors to consider, making the identification process very tedious. While people often try to make generalizations on how to identify them, Gagnon says there is no one way to identify any mushroom. The description of one mushroom could match that of a totally different one.
“A lot of mushroom books have a key where you start by saying, ‘Does it have gills, pores, tubes or teeth?’”she said. “‘Does it have a stem or does it not have one? Are there decorations on it? ….’ There are so many things to look at when identifying and the rules aren’t across the board, so you really have to learn each mushroom or least genus of each mushroom.”
While it’s important to be confident in the identity of a mushroom, confidence can be a killer.
“Sometimes when people are new they start to get a little confident,” Gagnon said. “Deadly mushrooms I think make up 0.2 percent of all the mushrooms in the world, so it sounds very small, but they occur a lot. They’re here all the time. There’s a mushroom called Galerina marginata, also called funeral bells or deadly Galerina, and it looks very much like some more edible mushrooms.”
Gagnon cited a time when someone posted a picture on social media announcing that she found what she thought was wild enoki and was going to cook with them for Thanksgiving. Come to find out, it was actually Galerina.
“I [was] desperately trying to reach her and message her not to eat those,” Gagnon said.
Luckily she saw Gagnon’s message before it was too late.
Common edible mushrooms
According to Gagnon, some of the most common edible types in the state are chicken of the woods, hen of the woods, chanterelles and black trumpets. The following descriptions come from Michael Kuo at mushroomexpert.com.
• Chicken of the woods (Laetiporus sulphureus and Laetiporus cincinnatus)
Characteristics: Perhaps the most obvious characteristic for this mushroom (Laetiporus sulphureus) is its yellow and orange colors, but the suede-textured caps eventually become dull, sometimes almost white as they age. They can grow to be 90 centimeters across with overlapping clusters and no stem. Their flesh is thick, watery and soft when they are young, but becomes tougher with age.
Where they grow: Chicken of the woods (Laetiporus sulphureus) is a saprobic mushroom found living on oak trees, dead or live ones, and sometimes on other hardwoods as well. Gagnon adds that Laetiporus cincinnatus has a white pore spore surface with rose and peach colors, and this mushroom appears to grow near hardwoods from the ground.
• Hen of the woods (Grifola frondosa)
Characteristics: Hen of the woods has clusters of brown caps spanning 15 to 40 centimeters across and 10 to 30 centimeters high. Each individual cap is around 3 to 14 centimeters across, can be dark to a pale gray-brown and are usually fan-like in shape.
Where they grow: These mushrooms can be found near the base of oak and hardwood trees.
• Chanterelles
Characteristics: There is an unknown number of chanterelle species, and not all will match any given description. In general, they are usually recognized as being medium or large-sized mushrooms ranging from yellow to orange in color. They are known for their fruity aroma, similar to the smell of apricots.
Where they grow: Chanterelles do not tend to have any specific mycorrhizal relationships. They are usually found in hardwood forests.
• Black trumpets (Craterellus fallax)
Characteristics: The cap and stem of black trumpets are not as clearly defined as in other mushrooms. While they are black, their outer surfaces can turn yellow or orangeish as the spores mature. They stand about 3 to 9 centimeters high and 1 to 5 centimeters wide with smooth, sometimes slightly wrinkled outer surfaces and have thin, brittle flesh.
Where they grow: Black trumpets are mycorrhizal with oaks and possibly other hardwoods as well and are usually found in mossy areas.
According to Gagnon, they can also be found in dead oak leaves. She says they grow in small clusters or scattered loosely down embankments and slopes where water travels after rainfall.
Common toxic mushrooms
These descriptions also come from Michael Kuo at mushroomexpert.com.
• Jack O’Lanterns (Omphalotus illudens)
Characteristics: Jack O’Lanterns, often confused with chanterelles, are bright orange mushrooms with gills that run down the stem and spores that are white or pale yellow.
Where they grow: You will find these mushrooms often growing in large clusters on buried roots or stumps.
• Deadly Galerina or funeral bells (Galerina marginata)
Characteristics: Deadly Galerina are fairly small mushrooms with brown or tawny colored caps
Where they grow: They grow on rotting hardwoods and conifers.
Gagnon adds that they can also be found in mulch.
Cooking with mushrooms
From broth to tea, the possibilities are endless when it comes to cooking with mushrooms. Each mushroom has its own flavor, which is something you likely have not experienced if you’ve only ever had mushrooms from the grocery store.
“In the grocery store, if you buy a button mushroom, a baby bella or a portobello, those are all the exact same mushroom at different stages of growth, so they’re not going to taste much different,” Gagnon said. “If you don’t like mushrooms and that’s all you’ve ever had, I would always suggest trying wild mushrooms because … each mushroom has a completely different flavor.”
One of Gagnon’s favorite mushrooms to eat is chicken of the woods. When it’s young, she says, it has a moist, meaty texture with a hint of lemon flavor, and as the name suggests, can be prepared the same way you would prepare chicken for many dishes.
“Hen of the woods [is] very similar but they have the tendency to be more flaky,” Fletcher said. “They have more of a grain to them so you can almost shred them. Some people will make a pulled mushroom dish with them depending on the size. I’m simpler in my preparation of them [as] I just want the natural mushroom flavor, look and texture to be there, so I’ll just do a quick sauté with oil or butter, salt [and] maybe a little … garlic and let them speak for themselves.”
Gagnon adds that hen of the woods, which she says has an earthy umami flavor, is very versatile, makes for a great chicken marsala, and can be pickled and made into jerky.
Chanterelles, on the other hand, have a fruity aroma according to Kuo. Fletcher, who says their texture is soft and meaty, loves to pair them with corn as the earthiness of the mushroom pairs well with the sweetness of the corn.
According to Fletcher, there are some classic Italian recipes that call for mushrooms. Black trumpets, which have a strong, sweet aroma and nutty, smoky taste according to Gagnon, are often the one of choice for risotto. Mushrooms also offer nutritional value, according to Milligan. He gives the example of king oyster mushrooms, which have five grams of protein, fresh weight, and all 11 essential amino acids.
In order to reap the nutritional benefits, he says almost all mushrooms need to be cooked, as humans do not have enough of the necessary enzymes to break down the mushroom’s cell structure. In fact, some mushrooms are toxic if eaten raw. Button mushrooms, brown mushrooms, baby bellas and portobellos, which are all the same species, contain chemicals that do not flush out of your system but instead build up in your liver when consumed raw. Heat is required to cook these chemicals away.
Buying fresh mushrooms
Two mushroom varieties that you are likely to find at local farmers markets this season are chestnut mushrooms and black oyster mushrooms. These mushrooms are listed on Joyberry Farm’s website as seasonal mushrooms as well as on New Hampshire Mushroom Co.’s website as mushrooms that they cultivate. Joyberry Farms attends the Bedford, Nashua and Salem farmers markets, and New Hampshire Mushroom Co.’s products can be found at the Concord farmers market.
Once you get them home, Fletcher says, it is best to keep them in a cool, dry place, ideally the refrigerator. As far as when to eat them, he says the fresher the better.
“You want to try to eat them as soon as possible because the quality of them is just going to diminish [and] you’re not going to get as much flavor out of them,” he said.
According to New Hampshire Mushroom Co., phoenix oyster mushrooms have a mild flavor that makes for a great addition in creamy soups, over pasta, with eggs or other lighter dishes. This fluffy, woodsy-flavored mushroom, as reported by Joyberry Farms, is very versatile and is also great when sautéed with butter or olive oil, onions and garlic.
Chestnut mushrooms have a nutty flavor that goes well in gravy, stuffing, stir-frys and roasted with chicken, according to New Hampshire Mushroom Co.

Dyeing with mushrooms
One of the things I was most surprised to learn during my walk with Gagnon was that mushrooms can be used to make dye. According to Allison Allen, this is a fairly new phenomenon.
“The earliest publication on using mushrooms to get a rainbow of color is from the 1970s from Miriam Rice out of Mendocino, California,” she said. “She was a natural dyer and was drawn to experimentation with it … found mushrooms and threw them into a pot of boiling water, simmered them with wool and, lo and behold, she started getting really promising results of color. We’re still in our infancy of discovery with what fungi can do as far as getting color.”
Allen started her business, Mycopigments, a term she coined back when she started dyeing with mushrooms in 1998, in 2011. From Seattle, Washington, Allen travels where she is requested to hold workshops. Having formerly lived in Massachusetts right on the New Hampshire border, she would often forage mushrooms in New Hampshire, and still comes back to the Granite State to collect mushrooms for dyeing.
“It’s a pretty simple process … and there are some nuances to testing mushrooms for color that I teach in my workshops,” Allen said. “Basically, you boil the mushrooms and you add the fiber and then that mushroom imparts color into that fiber and it’s permanent … brilliant dye.”
When choosing what fiber you want to work with, Allen says that wool, or other protein, animal-based fibers like silk, work best. In some instances you can even add mordant, mineral salts such as aluminum sulfate or ferrous sulfate, to intensify, brighten or darken the colors. For efficiency, Allen prefers to dry her mushrooms before using them for dye due to their high water content.
“It takes away the guessing game of how much mushroom you have to dye your wool,” she said. “When you’re dyeing wool you use one part mushroom to one part fiber by dry weight, so if you have an ounce of wool, you’re going to need an ounce of dry mushroom, which is actually a lot of mushrooms. But if you had an ounce of freshly picked mushrooms, depending on where you are with the rain cycle, they could be 99 percent water and so that ounce isn’t very much mushroom dye material. It’s just water so you can miscalculate and get disappointing results, so by dehydrating them you take away that guessing part.”
One New Hampshire mushroom that is suitable for dyeing is Cortinarius semisanguineus. These are small mushrooms, about 2 inches across with a mustard-colored cap and blood-red gills and result in a bold red when used with aluminum sulfate mordant. Red dye, according to Allen, is historically considered one of the most precious.
Dyer’s Polypore is a fairly common mushroom in New Hampshire that grows with conifers and pine.
“It is one of the strongest dye-makers in the fungal world, so a little bit goes a long way for that mushroom,” Allen said. “If I find it fresh and young … [I] can get away with using one part fungus to five parts fiber. … It will make a brilliant yellow and a deep gold and a nice olive green depending on how you extract the dye and what mordants you add.”
It is fairly simple to achieve yellow according to Allen. She breaks up the fungus into smaller pieces and adds a splash of vinegar to the mix. If you’re more advanced, you can add modants to get the yellows to come out, but vinegar does the trick just fine, she says.
To get a green hue, add iron by using ferrous sulfate power. You can even use iron vitamins, Allen says, after washing off the coating.
The most complicated color to achieve from dyeing with mushrooms is blue. To get a dye this color from mushrooms, Allen says you need identification skills, as very few mushrooms have the potential to make blue, access to pristine forests and a little bit of open-mindedness on the definition of blue.
“Blue is really hard to achieve in the mushroom dye world, especially as a beginner,” Allen said. “You have to have the right mushroom, you have to pre-mordant your fiber … then you have to monitor the pH of the extraction and then you can get, if you’re lucky and the temperature didn’t get too hot, some blue-green shades.”
Mushrooms in New Hampshire that have this potential belong to the Hydnellum, Sarcodon and Feldon genuses.
A mushroom that proves that what you see isn’t necessarily what you’re going to get for dye is Tapinella atrotomentosa, a suede brown-colored mushroom with tan gills that makes purple without any mordants and a deep forest green when iron is added.
According to Allen, the most prized dye species in New Hampshire is the Hapalopilus.
“This mushroom makes a purple dye that is dark and deep and really permanently binds to the fiber, so in that way I think it’s one of the most precious purple dye makers in the world because other purple sources tend to have some fading and some trouble with sticking around.”
According to Allen, mushroom dyeing is a very approachable mushroom hobby.
“You go out and you forage them and you don’t have to worry about if they’re edible or poisonous or anything,” Allen said. “it’s a really accessible way to get your hands on mushroom hunting without taking any risks at all. It’s a way to get engaged with nature and access these colors.”
