The Perennial Paddock: Mycelial Madness

Nothing made me more joyously certain that I had created a real, albeit tiny, ecosystem in my suburban yard than when the first mushrooms grew among perennial plants rather than in a grow-bag or other artificial arrangement. Last year two kinds of mushrooms spread from spawn I had introduced and appeared far from the original “planting.” I was ecstatic; the mycelial Internet was forming! And this spring I was even more gratified to find a big cluster of Stropharia rugosa-annulata pushing up through the mulch months before I had expected to see any mushrooms. By perfectionist standards they were  overly mature when I discovered them, as evidenced by size, lightened cap color, and the cracks in the cap. But I am no perfectionist and knew that they were still perfectly good to eat.

So a few notes on introducing mushrooms, in no particular order:

1. Stropharia rugosa-annulata is the easiest mushroom  to grow in your garden. Even here in the high desert, it thrives in a deep mulch of straw and oak sawdust. In my opinion the almond agaricus is the most delicious, but it is more finicky and less productive. I have grown oyster mushrooms in containers, but this year I’m experimenting with introducing them into more unlikely spots. I’ll report back.

2. Get good spawn. Mine came from Field and Forest Products, and it was ready to grow.

3. Know how to indentify the mushroom that you introduced. Know its field marks and identify it before you eat it. When you create a good outdoor environment for mushrooms, you are not in complete control of what grows, any more than you are immune to weeds in your garden beds.

4. Be aware of how many commercial mulch products are treated with fungicides to prevent fungus from moving in. If you want select funguses to move in and thrive, you need to avoid these products.

5. Cook and eat with a sense of reverence and awe for the complex and extraordinary interactions of nature. If you want to learn more about this, Mycelium Running, Mycelial Mayhem, and Radical Mycology are useful books.

I sautéed my mushrooms in olive oil with generous additions of green garlic and fresh thyme, then removed them from the skillet, set aside in a warm spot, and scrambled some eggs in additional olive oil with a little salt. When the eggs were cooked, the mushrooms were folded back in. Simple as that. Scrambling is an underestimated technique. In this case I cooked the eggs fairly firm, for texture contrast with the softer mushrooms.  I framed the fragrant heap with a couple of slices of bacon. It made a quick delicious dinner, mostly from my own property, and was a culinary salute to the mycelial web that underlies, well, damn near everything.

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.

DCF 1.0

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.

My Winecap Mushroom Bed

Early this spring I was putting down straw mulch around some new plantings in the shade and decided to order and incorporate some spawn for the winecap  mushroom, Stropharia rugosa-annulata.  I have never grown or tasted this mushroom before, and so I was very excited yesterday when a young friend pointed out “a giant mushroom” under one of the new little saplings.  My first winecap was a healthy 6 1/2 inches in diameter.  I cooked it plainly in butter with a little bit of salt, and it was perfectly nice but I would say not significantly  better than store-bought cremini mushrooms.  Still, my homegrown mushrooms are deep organic and came from my own land, so of course I favor them,  and they benefit the soil and the growing plants as well as me.

The advantage of Stropharia  is that it is fairly rugged and easy to grow. I am told that it grows much better in deciduous wood chips than in straw, and at the very least I should have mixed in some deciduous wood chips or put some on top, but it is one of those things that I meant to get around to and haven’t done yet.  Maybe I will still top up with some wood chips.

They grow well in the paths between garden beds, and once you have them established I am assured that you can move shovelfuls of the substrate around and start new  mushroom beds pretty much at will. The presence of fungi can be very important to the health of plants, and for much more on this fascinating subject I recommend reading “Mycelium Running.”

Here’s an important safety bulletin: just because you “planted” mushrooms in a specific spot, it is not safe to assume that any mushroom that comes up in that spot is what you planted.  There is absolutely no substitute for knowing the identification points for the mushroom you planted as well as for any poisonous look-alikes.  The mushrooms that I grow in my garden, oyster mushrooms and Stropharia, are easy to identify so this is not a difficult task.

The hugeness of the Stropharia  mushrooms can make your whole garden seem Wonderland-like and magical. It might not be the very best eating mushroom there is, but it is quite wonderful to have a visitor gasp and say “Ooh, what is THAT?”
