We return to the amazing mushroom walk that happened after a recent Great Big Rain…

121206-1800

I wandered around under the trees in a daze, happily entranced by the glories nestled among the deep, soft leaves. Every step brought new wonders!

121206-1803

A super-delicate little shroom. Compare it to the size of the two seedlings. You can see the gills through the cap. It has a scallop-edged ring around the stem.

121206-1807

Another tiny micro-dome. This one has fabulous fractal fur.

121206-1811

Above: A contender for favorite photo of this fungi-adventure. The visual space is divided up very artistically. You can see them in different stages of development. The mushrooms themselves are amazingly handsome!

I am pretty sure these brown-scaled beauties are Lepiota rachodes – which are deliciously edible – but I would definitely check the books before having any for dinner.

121206-1817

A pair of fluorescent shrooms caught in an intimate embrace. These are either Boletus or Suillus, both of which are pore-fungi (no gills). The underside shows the spongy-looking pores where the spores drop.

There are dozens of kinds of orange-red-yellow pore fungi that look a lot like this. All of them are mycorrhizal fungi that exist in mutually beneficial relationship with tree roots. Some are edible, some are poisonous. Do not eat!

121206-1824

Here is an aging Boletus, falling over in the late stages of decay. The white layer is actually a different kind of fungus, a mold that is the primary decay organism in this case.

Kind of picturesque, no? But wait, let’s go around and look at the cap…

Mom Nature outdoes herself at every turn.

Another winter storm rolls on through bringing wetness and more wetness, turning everything gray and shiny. Not a good day for gardening, but great for growing things.

121223-0945

What glorious fractal ripples in the transparent water puddles!

121223-0946

Gray on gray can be beautiful too.

Are you tired of mushrooms yet?

You’re kidding, right?

We continue the amazing mushroom walk that happened after a Great Big Rain not so long ago …

121206-1717

For a while, no new shrooms showed up. I looked in all the usual places, like this rich, red leaf litter beneath a north-facing wall. I wonder what cool critters live under there?

121206-1722

No mushrooms here, but wow, what a cool composition of rock, moss, and organic debris!

121206-1731

It was not until after I passed the school that the grove of trees in front of SRI became visible. On the left side of the street, an old, open forest of different kinds of trees, and under them, an unbroken stretch of mature, relatively undisturbed leaf litter.

Just barely visible in far left background of the photo above, a tiny row of white dots at the base of a tree. What do you suppose those are? Between here and there, there was much to see.

121206-1737

Possibly my favorite fungus in this adventure. Dark, ear-like folds with prominent gills, and of course! The obligatory fungus fly, reddish brown, perched daintily on the edge of a cap.

121206-1743

A pale yellow, wavy-edged wonder and gosh darn if there isn’t another fungus fly!

121206-1747

A perfect dome, with a delicate translucent edge. No fly this time.

121206-1750

Who could resist photographing these three little charmers?

Next: more forest floor charmers

You may recall Elizabeth’s new ecogarden with the redwood rounds, the beehives, and the chickens.

These days we are calling them deep nature gardens, but the project in Elizabeth’s back landscape has continued. There was a break during the summer, partly because this nature garden space is non-irrigated, so not much happens during the dry California summer, and partly because I needed some time to figure out some of the details of the deep nature gardening business.

Changes since our last update include the removal of the walkway made of redwood rounds. Elizabeth sometimes visits the chickens at night, and does not want to risk tripping on the wooden rounds in the dark. Sounds reasonable to me!

Instead, for now we will create a leafy pathway using some of the large fig and persimmon leaves that cover parts of the back yard in autumn. Later we might create a path using crushed shells or small gravel.

Some of the redwood rounds will be used to make pathways into the deeper recesses of the garden.

121207-0717

Above: During the summer we dug a little rain garden, marked out by the sticks in the photo. A test with a hose spray showed that sure enough, it works! Look at that sweet puddle. To the right of the rain garden is the path to the chicken run, now free of redwood rounds. At the left, under the edge of the fig tree, we have created a low mound using the soil removed from the rain garden. In the foreground is a plum sapling that we want to keep.

121207-0724

Above: Months have passed, and the rains have come. The rain garden and the low mound have both become covered in a mixed carpet of buttercup oxalis (Oxalis pes-caprae), cutleaf geranium (Geranium dissectum), common chickweed (Stellaria media), and many more kinds of sprouts.

Trees have lost most of their leaves, covering the ground with wonderful-nutrient rich food. In the background, between the rain garden and the persimmon tree, the path to the chicken run is now covered with leaves.

121207-0732

The lush, green carpet is certainly beautiful, but the highly invasive oxalis is overtopping almost everything else, and if nothing is done it will hamper many interesting kinds of plants that struggle to compete for nutrients and light. So it is now time to do some serious thinning.

The oxalis has deep bulbs, very hard to extract. For this first round of thinning I did not even try to dig down to the bulbs. I simply pulled up everything from the bulb up, by grasping each plant firmly just below the crown with two fingers. If this is done correctly, you end up holding the green plant and a long, tapering, white underground stem. The stem can be as long as a carrot, though it is much thinner. Like all the non-bulb parts of buttercup oxalis, it is edible. Sweet and tangy!

121207-0743

I worked in a patchwork pattern, focusing especially on the low bank, where some pretty rocks were added during a non-photo visit while it was still summer. I’ve also cleared out part of the basin of the rain garden, leaving behind a few patches for artistic balance.

Because the bulbs are still underground, many of these buttercup oxalis plants will grow back. The new growth will be flatter to the ground, smaller, and easier to pull out. There may be two or even three of these re-sprouts from each bulb, but eventually the bulbs will become exhausted and die.

What about the rest of the oxalis-dominated area? The plan is to continue working in patchwork patterns, clearing one area and then another, always leaving behind any interesting plants that managed to sprout between the oxalis. Discovered in the above clearing operation: miner’s lettuce, groundsel, scarlet pimpernel, and many small sprouts I did not recognize.

Am I worried that the sorrel and other fast-growing plants will get ahead of me? Nope, as long as I keep coming back I can move faster than they can. Look how much I was able to clear in just two hours or so, then consider that it took nature more than three months to grow that carpet of green.

The fig tree in the background above has been pruned so that it is possible to walk underneath — but please, let’s stay on the redwood rounds!

121207-0753

Above: A closer view of the rain garden and the bank, with a row of rocks holding it up. At the right, redwood rounds lead behind the bank. At the far right, the edge of the leaf-litter zone under the fig tree.

121207-0759

Last, this view of the far east corner, under the newly pruned fig tree. Big, floppy fig leaves cover the ground, partly smothering the oxalis and other plants trying to grow there. Lots more wait to fall. This is good, we want to create a nice deep layer back there. Any leaves that land on the rain garden or bank will be tossed into the east corner to make it even deeper.

Also in this zone are some irises that need pruning, some old, tangled roses that need shaping, and a very out-of-place palm sapling. That one might have to go. Eventually, it would be nice to add some native shade-loving shrubbery.

It was nice to get back to work in this happy little garden space. Stay tuned for more updates!

121219-1542

Yes, there has been a break from posts. What can I say… holidays, computer glitches, overwhelm. Sometimes you just have to back off for a while.

The changes have been good, all things considered. Deepest thanks to all of the great folks out there in this holiday time! Best wishes to all.

Where were we? We left off right in the middle of a fun mushroom walk, but before we continue that adventure let’s check in with a garden we have not visited much in recent months…

Next: back to Elizabeth’s garden!

We continue our mycological meanderings with the first Boletus encountered…

121206-1622

It was in a moist, low place among live oak litter. Accompanying it, from the lower right: a seedling of petty spurge, a very tiny winter cress in the shadow of an excellent rotting branch, and an unknown plant at the top.

Boletes have pores underneath instead of gills. The spores float down vertical tubes and out into the air. The caps often have a felty, rough look and decay in wonderful, artistic ways. Many of them turn blue or green when they are bruised. That does not necessarily mean that they are (or aren’t) poisonous!

Something seemed to be glowing in the shadows…

121206-1633

The photo above does not adequately convey the way the bright white rims of these three stood out. Naturally, there is the seemingly obligatory fungus fly.

121206-1649

At the base of a tree with beautiful rain-enhanced bark, this neat row of big fleshy mushrooms with wavy caps.

Suddenly… mushroom pay dirt! In a front yard under a very sick, almost completely dead oak tree, an amazing outcrop of fungi.

121206-1644

At first it seemed like there might be several different kinds, but then the forms merged together: this could all be Armillaria mellea, the honey mushroom, commonly seen emerging from dead or dying wood of many different kinds.

While this fungus might not have been the original reason why the old oak tree is dying, it is certainly making it happen a whole lot faster.

121206-1653

This young clump emerged from the base of a multi-branched stump. Definitely lignicolous (taking its nutrients from wood). In the lower right of the photo, green leaves of delicate winter cress, closely related to Arabidopsis thaliana, the miniature rock-cress that is so popular among genetic researchers.

121206-1701

Another sweet young clump, nestled among delightful micro-flora of the forest floor, also emerging from dead oak stems.

121206-1704

An older clump, fully expanded and just beginning to decay, probably coming from an underground oak root. Note the tasteful white narcissus.

Next: Jackpot!
