Oh the weather outside is fungal - It’s like a mushroom jungle

Mushrooms are popping up all over California thanks to the wet rainy weather we have had across the state recently. They seem to magically appear overnight, like umbrellas on a sunny beach day. This fascinating occurrence doesn't actually happen overnight as it may seem, but they appear once moisture becomes available. Mushrooms expand rapidly by absorbing water from the surrounding soil and consequently ‘pop' out of the ground.

Mushrooms are the fruiting body of a fungus and come in myriad shapes, sizes and colors. They are typically the only part of a fungus that can be seen because the mass of the organism is located underground.

There are approximately 14,000 different classified species of mushrooms, here are a few of my favorites:

Agaricus campestris (fairy rings): According to UC IPM, fairy rings get their name from the ancient belief that mushrooms grew in circles where fairies dance. Fairy ring fungi can cause circular rings in grass, ranging from 1 to 12 or more feet in diameter. (Photo: UC IPM / Jack Kelly Clark)



Boletus edulis (king bolete): A mighty mushroom of the mycology world, king bolete can be an exciting find. With a cap up to 10 inches across and a thick stem, these club like mushrooms have a wide range. In the home landscape, they can most commonly be found under conifer trees planted in turfgrass. (Photo: Strobilomyces)


Laetiporus sulphureus (chicken of the woods): A showy and beautiful shelf-like mushroom, chicken of the woods is easy to spot because of its bright yellow color. They most frequently grow out of wounds on trees and each ‘shelf' can be up to 10 inches across. (Photo: Bruce Hagen)


Nidula Candida (bird's nest): Like their name implies, these small mushrooms are reminiscent of birdsnests, complete with tiny eggs. These mushrooms are most commonly found on decaying wood, typically on fallen trees or in soil with bark mulch. These tiny mushrooms aren't easy to spot as the largest caps are only ½ inch across.

The next time you see mushrooms, consider what might be happening underground in your soil. For more information on mushrooms including identification and management, visit UC IPM online.

Enjoy the wet weather and the next time you find yourself excited over a new fungal find, here is a jingle to celebrate the season:

Let it Rain (sung to the tune of ‘Let it Snow')
by Ann King Filmer

Oh the weather outside is fungal
It's like a mushroom jungle
But since we've got much to gain
Let it rain! Let it rain! Let it rain!

Homegrown/Backyard Oyster Mushroom Cultivation

I recently attended a 4-hour workshop on homegrown/backyard mushroom cultivation organized by Biofuel Oasis in Berkeley, California.  Patty and Ray Lanier of Mushroom Maestros located in both Oakland and in Lake County, California, were the featured speakers of this seminar. 

The workshop began with a Powerpoint presentation on a brief history and folklore of the mushroom, the life cycle of a mushroom, and how mushrooms play a part in our ecological system.  After the Powerpoint presentation, Patty and Ray led the group through some hands-on projects, which is the focus of this blog entry. 

I was surprised to learn how easy it was/is to cultivate some varieties of mushrooms at home, specifically, the oyster mushroom and wine cap mushroom (king stropharia).  Below are instructions on how to cultivate oyster mushrooms at home.  Cultivating wine cap mushrooms is even easier and will be discussed in one of my upcoming blog entries.

Oyster Mushroom

Oyster mushrooms are aggressive and eager to grow. 

Materials needed:

1.       Large pot (e.g., a canning pot)

2.       Large colander

3.       Large mesh bag (e.g, an onion bag from the supermarket)

4.       1 bag of mushroom innoculent (can be bought on-line)

5.       1 cylindrical plastic bag (e.g., the plastic bags that newspapers come in or a large plastic bread bag)

6.       1 bag/jar of mushroom grain spawn (can be purchased easily on-line)

Step 1: Pasteurize (not sterilize) clean wheat straw (note: not hay, but straw) which you can purchase inexpensively from a well-stocked feed store, in 150 - 180 F degree heat for 45 - 60 minutes.  It may help to place the wheat straw in a mesh bag like an onion bag, to keep the straw together. 

Step 2: After you have pasteurized the straw, let it dry by placing it in a colander.

Step 3: Sterilize all work surfaces, tools, your hands, etc., with rubbing alcohol.  Empty the mesh bag of its straw contents and spread the straw (straw should be warm to the touch) onto a sterilized surface so that so that the straw layer is 2-3 inches thick.

Step 4: Take handfuls of the mushroom grain spawn and toss it onto the straw until the grains dot the surface of the straw.  Work the grain spawn into the straw. 

Step 5: Stuff the straw into your cylindrical plastic bag, compressing the straw enough so that the bag is firmly (but not overly) packed.  Tie the bag off.

Step 6: Take a nail or a sharp pair of scissors and pierce the bag, making random 1-inch cuts all over the bag, but not to the point where the straw begins to fall out.  This is to aerate the bag while keeping a moist environment for the spawn. Wipe the bag down with alcohol to keep it sterile.

Step 7: Place the bag in a shady area indoors (i.e., does not receive direct sunlight) in an area where the temperature is kept between 60 – 75 degrees.  Keep the bag moist but not damp, by spraying with a spray bottle filled with water.  You should see signs of oyster mushrooms in 2 weeks (the log will turn white), at which time, you can either keep the bag indoors or locate it in a shady part of your yard, protected from the wind and sun and heat.  When the caps of mushrooms flatten out, it is time to harvest.  Don't wait too long, as the mushrooms can grow past its prime in just 1 day.

Inter-planting Fruit Trees With Veggies

Yes, you can have it all in a relatively small back yard space:  Fruit trees and veggies.  Our “mini orchard” is on an oblong plot that’s about 25x15’, a sunny plot that came with the house we bought last summer.   In that space there are 3 dwarf plums (Prunus spp.), 2 apricots (P. armeniaca), 3 cherry trees (P. avium), 2 peach trees (P. persica), and an apple (Malus domestica), all of unknown varieties.  Our fruit trees are about 5 or 6 year old mostly dwarfs (I think), and if not, they got dwarfed anyway by my pruning saw and loppers last December, when I pruned both for shape and fruit production.  My rule of thumb with fruit trees is that if it is higher than I can reach, it gets lopped off.  This permits easy picking of the fruit and avoids the need for ladders.  The pruning and thinning of the foliage, which I do about once per month (see photos) also allows more nutrients to get to the fruit, besides giving those veggies planted in between their 6-8 hours of sun.

The veggies we have include 6 tomato plants (Solanum lycopersicum) in cages, 2 clumps of squashes (Curcurbita pepo), Japanese eggplant (Solanum melongena), bell peppers (Capsicum annuum), a lemon cucumber (Cucumis sativus), 3 hollyhocks (Alcea setosa), and 2 sunflowers (Helianthus annuus).  The tomatoes have been so productive we have to give the surplus to neighbors and friends.  The eggplant and peppers have been slower to mature but nonetheless very tasty in stir-fries, especially with added portabella mushrooms (Agaricus bisporus) and fresh chard (Beta vulgaris), the chard grown in one of our raised beds in another location of the yard.

And so, another example of when less (space) is more (more intensively gardened).

UC Davis has a publication called The California Backyard Orchard, which you may find useful for tips on pruning, both in the dormant season in during the spring and summer months.  See

Frilly Mushrooms

I just came back from the pacific northwest.   I went for two reasons, which were family and mushroom hunting. I found many, but not the one I was looking for. My favorite is Trametes versicolor , commonly called Turkey tail bracket fungus.  This little powerhouse is so pretty! It does the whole neutral monochromatic color scheme thing all by itself.  It's quite common, which just baffles me even more that I couldn't find it up north. Not only does it resemble a frilly fairy skirt, or the tail of a turkey, it's ecologically amazing. For starters, it can be used to clean up collected pollutants from disastrous oil spills and is well known in Asia for use in cancer treatment.   

Anyway, I just ended up collecting some neat little mosses and lichens and came back home. Then we had this crazy rainstorm that blew over my fence. Turns out that old stump it was being supported by finally let go. When we propped the fence up again and removed the debris...guess what I found!!!!  I realize they're common, but I like to think they heard me calling.
NOTE: DO NOT eat mushrooms collected in the wild unless you have a professional mycologist confirm that the specimen is EXACTLY what you are collecting to eat.  The Master Gardeners of Solano County do not recommend people hunting and gathering mushrooms.

Mushroom collecting impacted by sudden oak death

A Northern California mushroom hunter blames sudden oak death for a dramatic decline in wild golden chanterelles, according to a feature story in the East Bay Express, but the article points to myriad pressures on landscapes that used to produce the edible fungi.

Mushroom enthusiast Todd Spanier told writer Alistair Bland that 10 years ago he could harvest nearly 200 pounds of golden chanterelles from a handful of patches.

"Now, I can go to the same canyons, do all the same hikes to all the same patches, and collect maybe five pounds of chanterelles," Spanier was quoted.

Among other things, Spanier blames sudden oak death.

"In places the forest looks like a checkerboard of dead trees," Spanier said.

The story outlines the other landscape impacts that may be partly responsible for the decline in wild mushrooms:

  • Grazing cattle, which gather in the shade of oaks and trample seasonal mushroom patches
  • Wild pigs, which tear up the soil beneath oaks rooting for acorns
  • Suburban sprawl and development

The tanoak — not actually an oak but still important for mushrooms — have meanwhile been decimated by sudden oak death in its native range along the central and north coasts of California. UC Berkeley SOD expert Matteo Garbelotto believes the tanoaks could disappear from some areas altogether, the article said.

Mushroom hunting is illegal in state and national parks and a permit is required for mushroom hunting in national forests. Bland said, however, that many avid collectors regularly break such laws. Spanier suggested there's a primal drive for collecting the rare delicacies.

"Wild mushrooms are our last connection to our ancestral hunting and gathering roots, and cultivated mushrooms can't replace that," he is quoted in the story. "If and when we lose the California live oak and tanoak, it's going to be tragedy in so many ways. It'll be a culinary loss, a cultural loss, and an ecological and environmental loss."
