The Fall Summation II: Mushrooms

I always felt that if I could grow mushrooms outdoors among my garden plants,  I would have a fully functioning little ecosystem even here in the desert.  This year, I finally achieved exactly that, and it’s one of the highlights of my gardening year. I should add that anybody who gardens is growing all kinds of soil fungi, but I wanted the edible kind. Three species came through for me. The first was the almond agaricus, shown above.  They are compost lovers, and I buried chunks of the spawn in a bed of compost that I was about to plant squash into. Unfortunately, the squash overran the bed and I only got a few mushrooms from around the edges, but they were very delicious.  This species really does have an intense flavor of almonds, and if you don’t love almonds you probably won’t want this mushroom, but if you do it is a special treat sautéed in butter and served alongside a nutty beefy piece of dry aged meat.

Stropharia rugosa-annulata, the wine-cap mushroom,  grows freely in mulched garden paths.  It will grow in pure straw mulch, and that is how I grew it at first, but there is no question that it tastes better if you incorporate some hardwood chips or sawdust in with the straw.  Even when grown in straw alone it tastes as good as a store-bought cremini or better, but once I incorporated some hardwood it became a treat. The picture  above shows how it should ideally look at harvest. The button stage, shown to the right, is tastiest but I can never resist letting one or two get huge. The picture below shows how it is more likely to look in my garden, because for some reason there are tiny little slugs that only seem to chew on this one mushroom species. But no problem, I just brush them off, and once it is washed and sautéed in butter you can’t tell that they were ever there.

Then there are oyster mushrooms, my favorite cultivated mushroom to eat and one of the easiest to grow.  I grow them in the shade in almost whatever receptacle comes to hand, usually laundry baskets lined with clear plastic bags.  For the growing medium I use a mixture of straw and hardwood sawdust, sterilized sufficiently with hydrogen peroxide solution, with a little alfalfa shake included to nourish the mushrooms.  I stick the whole rig under a dense shade tree in late spring, in an area where water from the sprinkler will hit it when I water, but I don’t make any other effort to keep it wet. I like to let oyster mushrooms get big, to the point that they are really meaty.  After cleaning them and cutting away the tough stem area I slice them in quarter inch strips and sauté  them in olive oil with salt until they have some nice brown spots, adding a little chopped garlic toward the end of the cooking.  They are more tender when small, but not nearly as umami and tasty. It’s the difference between veal and beef, and I have never been a fan of veal. Of course, if you want a milder flavor and softer texture, pick them smaller.

Today I finished “planting” several baskets and bags with the blue oyster mushroom, a subspecies of the common oyster mushroom that fruits at a lower temperature.  They are going in an unheated shed, and might fruit during the winter. Remains to be seen if this will work, but anything that prolongs the mushroom season is worth a try.

Oyster mushrooms are determined to grow. Recently I broke up a spent basket and put the mycelium in lumps under straw mulch, and today I found tiny infant oyster mushrooms poking out. I threw a frost blanket over the area and weighted it down with pavers, and maybe I’ll get a late outdoor crop.

Nothing fills me with quite as much satisfaction as seeing one of my mushroom projects cooked and on the table.  I am not sure why this is, except that their biology is so unique and fascinating and they are so essential, in one form or another, to life on earth.  They have some interesting medicinal qualities, but I don’t feel any great need for medicine and prefer to eat them because they are fascinating  and delicious.

I’m enjoying a book called Radical Mycology, which is a compendium of nearly everything that you can imagine about mushrooms, including a heap of medical advice which, in my opinion, should be taken with a very large grain of salt.  But it is addictive reading and will get you through many a long winter evening and give you ideas for new projects.

The Oyster of the Woods

There is nothing more interesting than mushrooms. Really. An independent kingdom of organisms, they have much in common with animals and their interactions with plants are complex and often beneficial. For a wonderful read about mushrooms and their biological role, check out Paul Stamets’s Mycelium Running, and you will be wonderstruck at the hypheal hijinks going on all around you.
They are extremely easy to grow for everyone but me.  I am convinced that mushrooms have a very important role to play in a functioning urban homestead, even here in the high desert.  So far, however, I have been unable to make that work out in practice.  I have tried spreading the spawn among existing plantings under heavy straw mulches, and putting the spawn in piles of hard wood chips, and so far have not had any significant success, due to lack of consistent moisture, lack of shade, dry air, and insufficient attention.  I have harvested a few mushrooms, but nothing to write home about.  That is why the below images below are borrowed, to show how easily it can be done in moister climates than mine.

Since I have finally accepted that it’s going to take more focus than just throwing some spawn around, my next attempt will be to insert plug spawn into damp hay bales in the dense shade of my black locust tree. I have also cut down a small Siberian elm recently and have a few pieces of suitable fresh log to try drilling plug spawn into. Next August I will harvest them, or not.
Meanwhile, many farmers’ markets have a mushroom farmer or two, and oysters can be found in our river bosque here and in many woods and forests if you are a knowledgable forager and know exactly what you are picking. Mushroom foraging is not for you unless you are prepared to study it seriously and know all your local toxics. No margin for error here.
However you get hold of them, good oyster mushrooms are just delicious. I love their earthy-almondy aroma and their meaty texture. I like them best simply pan-fried with a little macadamia oil and salt, but roasting them with a bit of butter and soy is awfully good, and so is grilling them rubbed with olive oil. The addition of a little chicken glacé early in the cooking stage so that it can cook into the caps suits their meaty flavor.
For preserving, I roast them with macadamia oil and salt just to the point that they are cooked through, cool them, bag, and freeze. When wanted, they can be thawed and pan-grilled until they get some lovely brown crunchy bits. I dehydrate the clean stems as long as they’re not buggy and grind them into oyster flour to thicken mushroom sauces and soups. I admit that I also open my little bag of oyster flour just to inhale deeply and recall the woods where I found them.
Yesterday I found that I had tossed more caps with macadamia oil and salt than would fit in my roasting pans, and stuck the surplus in the dehydrator. They emerged as delicious crunchy lightly browned Oyster Crackers. Yum. I will make more of those. A small pan-grilled cap on an Oyster Cracker would make a wonderful cook’s treat. In fact, a couple of them with nothing on top made a great cook’s treat…

A Hopeful Sign

Early this spring I was mulling over the issue of a long narrow patch of ground that gets water from my garden sprinkler but doesn’t produce anything. I decided to try outdoor mushrooms. It was a fairly foolish idea because the area is fully exposed to our desert sun, but I do not lack for the damnfool quality. So in March I covered the strip 10″ deep with loose straw, wet it down, spread a bag each of oyster and King Winecap spawn, and paid it no further attention. The oyster spawn produced nothing, unsurprisingly. But this morning I found a tiny baby Stropheria putting a head up to have a look around.
I hope it goes without saying that you don’t eat any mushroom without carefully identifying it, even if you planted mushrooms in that very spot. Get at least 2-3 good mushroom field guides and don’t eat unless you are 100% confident of your ID. A mushroom-loving writer once remarked that ” There are old mushroom eaters and there are bold mushroom eaters, but there are no old bold mushroom eaters.” Take it to heart. Anyway, unless I get more mushrooms I will let this one go to spore rather than picking it.
Even if I never harvest any mushrooms the project is worth it, because the presence of a small fruiting body above ground indicates the presence of a large mycelium entity that you don’t see. I can’t encourage people enough to read Mycelium Running by Paul Stamets to understand the importance of this.
My spawn came from Fungi Perfecti. They have a fascinating array of kits if you want to stick your toe into mushroom growing, and they offer a wide variety of spawn and instructional books if you want to produce mushrooms on a bigger scale.
