Let's face it, treasure hunting is fun. There is nothing I know that resembles treasure hunting as much as foraging for wild mushrooms. I am a science fiction fan, and mushrooms are the closest I can come to an alien life form coexisting with us under our very feet. Just like treasure hunting (and searching for aliens) there is a risk. The best weapon we have to minimize this risk is education. There are old mushroom hunters and bold mushroom hunters, but there are no old, bold mushroom hunters. Some of us like to hunt for the thrill of the chase--we like to watch birds too, and there is no munching involved. But many of us crave the taste of the wild. There is a safe way to do this. There are many good local organizations that will take you on a learning jaunt in mushroom country. Monadnock Mycorrhizza ( jsflynn@srnet.com ), and the Brattleboro Mycophagy Club (our of Bonneyvale Environmental Center (802-257-5785) have mushroom forays in Chesterfield. The Friends of Pisgah and the Harris Center do also, but not often.

There are over 5000 species of mushrooms in the United States. About 100 of these have poisonous varieties within them. Identification, no matter how much education and how many reference books, is not always certain. WHEN IN DOUBT, THROW IT OUT. Even poisonous mushrooms compost quite nicely.

Mushrooms for the table must be fresh. You wouldn't dream of munching on a pizza some dog has slobbered over. A lot of critters like ‘shrooms, so be sure you got there first. Some mushrooms keep better than others, and some can be air dried. Others, for eating purposes, must be cooked and used or frozen. When you first start hunting for edible mushrooms, don't try to learn too much as once. The amount of information is overwhelming. Learn a few, safe varieties at a time. We have a beginning here, with a few ‘shrooms that you can find on walks in Chesterfield.

One of the choicest morsels is the Morel, family Morchellaceae. They are available, if you're lucky, only in the spring of the year. Morels do not have gills. Their caps are similar to a sponge in appearance, and have a stalk which is HOLLOW, with a SINGLE CHANNEL, or stuffed with filaments like cotton. The caps can be creamy, buff, or brown. This morel is a very common type, and can be found in Chesterfield, and no, I will not tell you where. morel

stink horn The False Morel, Gyromitra (see below), can only be mistaken for a true morel by somebody who has never seen a morel. STALKS OFTEN HAVE SEVERAL BRANCHING CHANNELS OR ARE HOLLOW. I have never seen one of these in Chesterfield. What I have seen, in abundance, especially in Pisgah, are Stinkhorns, family Clathraceae. Again, once you see one, you won't have much trouble telling it from a morel. And once you SMELL one, you know where it got its name. It carries a dirty musky rotten odor.

The chanterelles, genus Cantharellus, are shaped like vases. These vases have ribs, which may resemble but are not gills. There are many sizes and varieties, and some of the most common (although never common enough) are quite small. The small, dark greyish brown chanterelle is a real gourmet treat. More common are the orange varieties. They often come right up out of moss, or cracks in rocks, often in clumps of 3 or 4, and I've seen them in Pisgah and Chesterfield Gorge. chanterelles

Jack O' Lantern Jack O' Lanterns are called look-alikes to chanterelles, but they don't look alike to me. They are almost PHOSPHORESCENT ORANGE, WITH SHARP-EDGED GILLS, and they often grow in clumps of 8 or more. They grow from the STUMPS OF TREES, or OTHER DEAD WOOD, but the wood and roots it springs from may be buried. Once you see it, you won't mistake it for chanterelles.

Oyster mushrooms are Genus Pleurotus. They look glorious, usually rather delicate and white to cream. They are often in the shape of an oyster shell, and grow on wood--often maple, beech, poplar or willow. They often sprout quickly from the wood after a rain, in clusters one atop another, and may have a pleasant licorice-like odor. They may have very short to no stems. Their gills are fragile, and there are no very close look-alikes. oyster

sulfur The Sulphur shelf, Laetiporus sulphureus, is a stalkless bracket fungi. This means that you find it as often overlapping fanlike shelves on the trunks of trees. It is bright yellow-orange to orange, and can grow quite large and lovely. It has pores rather than gills. Some people find this mushroom causes them gastric upset, whereas many people enjoy them without any untoward effects. It is shown here in place as well as from the underside view, in hand. Sulfur Shell

oldman Old Man of the Woods is pretty easy to identify, and is a bolete. Old Man of the Woods has, like most boletes, spongy pores on the underside of the cap, and not gills. It is Strobilomyces floccopus. It's shaggy, dry surface is very distinct, with coarse deep gray or black scales on a paler cap. It is edible, but one of the many that is not worth the harvest, as it is very "undistinctive" in taste.

Pholiota squarrosoides is also called sharpscales, and has a lovely, textured cap. Unfortunately, it resembles the shaggy scalecap which has been reported poisonous by some people. This is one to admire at a distance, unless you are a "shroom expert", and then you must weigh the risk carefully. I prefer to harvest the pictures only. Pholiota squarrosoides

honey There are many varieties of honey mushroom. They can be quite varied in appearance, as well as taste. Although many are a gastronomic delight, some people cannot eat them at all. They should be sampled with caution, and in very small quantities. They come in clusters, and their stalks grow together out of trees--often from stumps, since this fungi is quite parasitic to the tree. This is a late summer and autumn visitor. The Deadly Galerina is smaller, and usually brighter, and, unfortunately, lives up to its name.

Amanita muscaria, also called the fly agaric, is very common in the area. It is also usually easy to identify. It's cap is bright yellow to yellow-orange, and has a shiny surface with warty looking protuberances. In other areas it is red, with the same warty protuberances. The first time you go on a mushroom foray, ask someone to point it out. It is beautiful, but poisonous. Once you know it, you can avoid it. Amanita phalloides, also called the "death cup", is quite deadly. amanti

inky. Inky caps, family Coprinaceae, are very fragile, and quite unusual. They deliquesce. This means that the edges of the cap turn black and liquefy. There are edible (when young before they start to self-digest) and poisonous inky caps. Unfortunately, if you consume alcohol up to 5 days after eating some of the edible ones, you can suffer an Anabuse-type reaction. Anabuse is a drug given to alcoholics to prevent them from drinking alcohol. You can get an unpleasant surprise if you forget and take cough medicine or another medicinal containing alcohol after you consume these. The word "suffer" was used with careful intent. You DON'T want to experience this.

Jewel Weed is not a mushroom, of course, but it is a wonderful bonus you can gather at the end of a mushroom hunt. It won't last long away from its moist environment, but it is worth harvesting some. Cut it up and boil it with water in a stainless steel pot. Let the bright yellowish- red liquid cool, and strain it. This liquid should be frozen in ice cube trays and kept in your freezer for the summer. There is no better soother for poison ivy. Rub the ice cube over the irritated skin. The ice will add its mechanical inflammatory reducer. It is plentiful here, and can often be found near where poison ivy grows. jewel

jewel The Field, or Horse Mushrooms, Psalliota arvensis, also called Agaricus arvensis, are these marvelous little mushrooms which crop up on your lawn or in open fields after a rain, or in the morning after a dew in mid to late summer and autumn. They are one of the few mushrooms it is safe to eat raw. They have a ring around the stalk, and have no lower vulva--a cup at the base of the stalk, which is one characteristic which distinguishes these from the amanitas. The gills are generally pinkish, but turn dark brown when they dry. Grab them fast, because slugs and other critters like them too. Cut in slices, they dry well.

Mushrooming is fun. You sharpen observing skill, and can learn scientific techniques of spore printing and other identifying techniques. Take a basket along--mushrooms "melt" into a sticky mess when stored in plastic. Also take along some waxed paper bags. You want to ensure that mushrooms you cannot identify on the trail are kept separate from known edible varieties.

Mushrooming can be exciting even if you don't harvest any. But most of us are tempted. It takes education, but there are willing and able teachers in the area. To encourage caution, here is a some specific information on mushroom "defense".

There are at least 6 different mushroom toxin varieties, and each of these require specific therapy. Typical symptoms of mushroom poisoning gastrointestinal complaints. Other toxins, like bacterial and viral toxins, are capable of producing the same symptoms. The mushroom type must be identified for the most effective treatment. Supply refrigerated or air dried suspects to the Emergency Room staff.

MUSH2Poisonous mushrooms of the Amanita and Galerina genera secrete amanitin and phalloidin, which affect the blood, liver, kidney, and gastrointestinal tract within 6 to 24 hours. These are exceedingly dangerous. Expect to see blood in your urine, protein in the urine on testing, gastroenteritis and jaundice. Poisonous amanitas also contain ibotenic acid and muscimol, which hit the central nervous system. In 20 minutes to 2 hours, expect dry mouth, delirium, blurred vision, and a staggering walk . Those of the Gyromitra genus have monomethylhydrazine which affects the same areas as amanitin and phalloidin, but take 6 to 10 hours to act. Your blood cells will begin to break down, and you will experience nausea, vomiting, muscle cramps, severe abdominal pain, liver and kidney failure, and weakness. Coprinus mushrooms have coprine, which acts with alcohol ingestion--it produces an Anabuse effect in from 20 minutes to 5 days. In other words, you can eat them, and 5 days later have a glass of wine and end up with SEVERE vomiting. Your blood pressure may drop dangerously. Clitocybe and Inocybe poisonous ‘shrooms have muscarine, which hits the autonomic nervous system. Within 20 minutes to 2 hours your tears will be flowing, saliva will be dripping, you will be urinating frequently., and have diarrhea. Dehydration comes quickly. Psilocybe and Panaeolus mushrooms have psilocybin and psilocin, which attack the central nervous system. Within 15 to 30 minutes you can expect hallucinations, and a hyperactive state.

Don't let these symptoms discourage you. Start with identification only. You will go through baskets of mushrooms before you feel comfortable on your own. You will also gain a sizable collection of mushroom identification books and paraphernalia. You still may not be able to identify a mushroom. When in doubt, throw it out. Go with a knowledgeable group until you are familiar with the mushroom you plan to harvest. Education is your most important defense.
