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.

Backyard Mushrooms

For years I moaned and carried on about my inability to grow mushrooms as an integrated part of my urban homestead, and now I can’t stop them. All winter I grew oyster mushrooms in the garage on a substrate of recycled paper, and last month I put the theoretically depleted basket of substrate outside in the shade with the thought that when I got around to it, I would break up the broken-down paper and incorporate it into my mulch. Instead, the basket was within range of a sprinkler that I was using every other day to help some new plants get started, and produced another three pounds of mushrooms. So this might not  exactly be the Pacific Northwest around here, but the adaptable oyster didn’t care.

So my point is, as the Gangsta Gardener says, just plant shit. Plant what you would like to eat and don’t give up. Plants and fungi are resilient survivors and may astonish you at some point, even after initial disheartening failures.

The role of fungi in a healthy ecosystem is far-reaching and worth reading about. They are valuable beyond measure whether you can directly eat them or not. But my greed and gluttony makes me most interested in the edibles. Pleurotis ostreatus, the common oyster mushroom,  is vigorous and highly adaptable and also delicious, which works out well for my purposes. But I am experimenting with some other types. In an area of deep straw and mulch I put spawn of the wine cap mushroom, Stropharia rugosa-annulata, and it seems to be sending mycelia out through the straw. In August I’ll find out if it will fruit for me.

The mycelium above may grow into the mushrooms below:

Every year I make a new bed by putting down layers of cardboard and nontoxic paper recyclables and piling up a year’s worth of goat bedding on top. This is a mixture of goat manure and the alfalfa that she eats, and is as hot a compost material as you will find, so I do this in late fall or early winter, wet it down thoroughly, and let it compost in place over the winter. In spring, I start planting into it.  Generally, the first year I use hearty healthy unstoppable plants, such as mustard for greens and summer squash. They always flourish, and by the second year of the compost is finely broken down and will grow pretty much anything. This year I planted spawn of the almond agaricus mushroom, a compost-loving mushroom, into a first-year bed and will see what happens. But I was interested to note that a small shelf of oyster mushrooms poked out the side a couple of weeks ago. The oyster mushroom is not “supposed” to tolerate full sun or hot compost. To which I can only say, tell that to the oyster mushroom.

If you’re interested in learning more about offbeat ways of growing mushrooms, Mycelial Mayhem is a delightful romp through the casual side of mushroom growing. Mycelium Running is a classic about the role of fungi in ecology.

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.
