oyster mushrooms

  Oyster mushrooms found on a tree stump along a street in Ann Arbor.

 The cluster weighed one pound.

 They were delicious.

An extraordinary section of piled on construction - dwelling upon dwelling with no sunlight penetrating the six squared kilometer and 12 storey elevated lot, home to 50,000 residents, who live an ordered and complexly tiered life in incredibly stressed physical conditions - but still, space is made

Found this mushroom the other day and went on the web to try identify it. 
It appears to be a bolete covered with the white mycelium of a mycoparasitic fungus belonging to the genus Verticillium, a genus of conidial fungi. Same idea as the delectable lobster mushroom; a fungi-on-fungi arrangement.

As usual, my search yielded an overwhelming amount of new and amazing information about mushrooms. Including this ted-talk by Paul Stamets who, in the allotted 18 minutes outlines the extraordinary range, form, and frankly jaw-dropping histoire of these critical sentient fungi and six specific ways in which it could restore the health of the planet.

An article on BBC's website July 11 2015 about the "Wood Wide Web" can be read here. It details many examples of mycorrhizae; communication between plants via mycellia.

The article provides a link to a 5 min documentary on the work of Prof. Suzanne Simard, UBC Faculty of Forestry, who studies the underground communication network of trees;
"Mycorrhizal fungi form obligate symbioses with trees, where the tree supplies the fungus with carbohydrate energy in return for water and nutrients the fungal mycelia gather from the soil". There is a substantial text entry attached to the You Tube post which is a good read.

not bored, exactly......

These were some of the people in the room.

We had to be there.

You can probably tell.

The Battle of the Cucumbers and the Tomatoes

A bit late in the spring, but better to get going than not. Taking advantage of the offer of a load of soil from John, friend of neighbor, Nancy, I restored the raised bed a previous tenant had built. It's big, around 10 feet by 16 feet. They had built it well; layer of gravel, lined with heavy plastic, then soil on top. This way the plant roots are discouraged from tapping down into the ground below where the dreaded Black Walnut roots lurk, drooling their toxins into the glebe. A sure killer to many plants, it is essential to prevent contact. The new soil added to the weeded-and-turned original came from Ann Arbor's city-owned composting depot out on Platte Road.

 It is very rich.

I planted four cherry tomato, one heirloom, one mongrel, two thick rows of carrots, some green cabbage, some purple cabbage, some other thing and five plantings of cucumber. I also planted some rosemary (did not do well), some chamomile (struggling) Thyme, Basil, Silver Thyme, and Oregano as well as transplanted a bunch of mint. All that took a sweaty while. Some I did from seed, most from small potteds. 

It is difficult to adequately express the thrill/joy/pleasure/deep satisfaction of digging around in wormy dirt with bare hands and a trowel. It goes right into you.

Pleased with the orderly rows and overjoyed to see tiny sprouts emerge after a few week, I fussed and tended the plot, inspecting it closely for weeds and being careful to discern carrot from clover sprout. Other than following directions on the back of seed packets and running to the internet for every question that came to mind I just poked around and peered at the plants a lot.
 Nancy thought I might need more robust stakes. But the tomato plants looked so demure, so tame,- like those gremlins long before they find the swimming pool - so I didn't worry too much. Sure enough, as they grew I found myself racing against their imminent droop, driving everything I could find; sweeping-brush poles, tent poles, sharpened branches and even an old tripod into the ground to catch their swoon. 

Cucumbers began to drill out of the ground and go walkabout. Those things can really travel! I had laid out strings in order to remember where I had put things down and these were soon overwhelmed. 
The string was soon repurposed in the tying of vines to poles and stakes. Finally I nailed together a 10 x 4 x 2 foot frame which I lowered over the whole mess and to it tied long bamboo poles, both laterally and vertically, to support what has now become an inseparable union between the cucumber vine and the tomato plants. 

Here are the cucumber sprouts; two round leaves followed by a serrated leaf. It is when this third leaf appears that it is good to thin the herd.

The cucumber grows a spiral tendril out of its blossom part, and this waves about till it finds something to cling onto. It is fascinating to see how it winds itself and to what it attaches. Thin threads find tomato leaves and slowly take hold of them, gripping them but not tight enough to damage the leaf causing it to die. It is unnerving to see and realize this is somewhere in the 'decision-making" process of the plant. The cucumber vine is by now a bit weighty. It has loads of blossoms and a couple of emergent cukes! 

The tendril will find without any trouble a post or leaf or branch (although it may already be in possession of this piece of intelligence before it goes wandering) and will snake around it for one or more windings. Then, surprisingly, it doubles back on itself, following the opposite direction, at times backing up on the first wind a bit for extra grip. It is evident when one proceeds to undo the tendril, as I had to do repeatedly in order to save the poor strangled mint and the chamomile which were gasping and under the pressure.  
When one vine has found a secure grip on a pole, a second vine comes up and tendrils move out from each to find one another, winding about one another so that the second one is secured, too. Holding hands. Such cooperation! 

Preoccupied with this cucumber marvel, it took me a while to notice the tomatoes were doing the same thing. The tomato vines, now a number of feet in length would sail out from the center stem and turn this way and that, entangling their leaves in those of nearby vines, thus supporting themselves as they expanded their horizons. 
One day a thick vine kinked, succumbing to it's weight, and the leaves drooped. I was disappointed as there were clusters of small tomatoes on it. In a day or two, though, the leaves perked up again. 
Later when I was out along the road I passed someones big bushy Heirloom tomato plant and noticed one of it's stems, thick as a dog leg, had keeled over, too. It also did not die, I saw, just adapted. It's amazing to comprehend this self-sufficiency and interdependence among the plants.

Bees and butterflies are regular suppers now that the blossoms are open and so numerous.

Here is one forager upended into a blossom.

Here are the first two heirlooms to appear.

I barely had time to take a picture with the one hand before the other grabbed the pair and catapulted them into my mouth. No control.

Banshee snail (Helix Aspersa Fletus)

visits the house every evening, snacks on whole cabbages and any chicken parts left laying around. The moaning sounds emitted by this species are a combination of the movements of it's tail tip against the flagstone and high-pitched keening sounds it makes by sawing it's love dart over it's shell much in the manner of a violin bow against a violin.

Baking a Logic Board.

Nov 2013:     Update: 
2nd logic board bake yesterday.           It worked!       

Following the first bake in July, the problem resurfaced after about a month. 
I did not get a chance until now (Nov) to perform a rebake.  ( It can be done multiple times.)
It was a lot easier to go through the process a second time, and much faster.
This time I paid close attention to the finicky cleaning and application of the Arctic Silver to the processors. Drawing the heat from the processors is critical, it seems, and by all accounts it is worth the effort.

July 2013:      A few weeks ago my old Macbook Pro suddenly started flashing strobe-like and then froze. Very suddenly. A reboot, nothing. Halfway through the boot attempt a tinted curtain slowly descended, as of on a stage, with a message in three or four languages to reboot. This kept up, so after pulling the files off by booting as an external hard drive, I took it to Apple. Their diagnostics showed broken communication with the Invidia chip. The computer fell off the edge of Apple-repairable because it is more than 5 yrs old. It is now "vintage"(it feels like only yesterday). After a visit to a secondary establishment who talked up a whole bag of ozone-producing hot air I went online to any forums I could find on the subject before I offloaded it for parts. 
There is a lot of info about this Invidia problem with older MBPs posted all over the place. This chip is in many gaming systems so there are plenty of vested individuals identifying the problem along with posting details of solutions and follow-ups, as well, which is good. 

I followed the instructions step by step for taking apart the mac. Here is that info.

One thing that helped keep order in the process was to employ some regular adhesive tape turned sticky side up, secured with more tape attached to its edges, and set each tiny screw head-side down in the pattern of their location in the computer. 

Above is from the interior of the computer; all the screws on the logic board and the fans and the optical drive, which must be removed.

Then I watched this VIDEO to get a handle on what I was about to do: 

this is the underside of the top keyboard part with optical drive removed and perched there upper left and the two chips of ram removed and sitting on the lower right. The brownish ribbon thing has a 'snap' connector which needs to be carefully popped from the logic board as keyboard top is removed.

strips of tape secure the fans, (see right side fan flipped up on its tape) which i peeled back to pull them out entirely. using a small artist's paintbrush I swept the fans while holding it near the nozzle of the house vacuum cleaner. (nylon-stocking mesh over tip prevents important parts from shooting down the hose and co-mingling with revolting stuff you don't want to stick your hand in). ditto the rest of the interior of the computer, which collects a lot of dust over time and inhibits the effectiveness of the fans, I read.

 

BOARD UNDERSIDE VIEW

 In the middle of the logic board you can see the three big main chips with gray splodges of thermal compound on them. This compound provides conduction between the chip and the heat sink bar thing on the floor of the mac, which is in turn connected to the fans. The fans connect to sensors on the board, so they know to turn on when things heat up. 

Video makes things run really hot, so, I guess if any of these links are weak the system encounters problems. 

When replacing the board after the bake it is important to replace every connection again. There are twelve in all. (on mine. Not sure if that differs from year models up or down.) 

The following BLOG by Russel Heistuman I found very helpful.

Not only are the details on the problem and procedure clearly laid out, the author follows up regularly (he baked his 6 times!). Here is his BAKE procedure. It is worth spending time reading all the comments, too, as there is a lot to be gleaned from them.

One important thing is the thermal compound. It is important to:

      BEFORE BAKE: gently remove the old compound ,then clean and polish the surfaces, 

AFTER BAKE: apply 'surfectant' (however the hell you spell it) which enhances the conducive properties of the newly applied fresh compound - a one-inch line oozed onto the chips, before reassembling the computer. 

I found an equivalent Arctic 5 thermal compound kit at radio shack and the Torx 6 and Phillips #00 at Sears (which sells them individually)

BOARD TOP VIEW

In addition to the dozen or so screws which are removed, there are also some foam buffer pieces sitting on top the usb ports, as well as two plastic gripper/washer type things at the rear edge of the board which pull off easily - if they haven't already fallen off during the extraction. In short; anything that is likely to melt in the oven should be pulled off.

The RAM had already been removed (this is pulled following the battery removal at start).

Line a baking sheet with aluminum foil and roll additional pieces of foil into four balls. The board will sit up on these raising it a couple of inches. Helps to get even heat all round I suppose. 

Preheat oven to 375 F and place board-on-baking sheet inside for 7.5 mins (if in any doubt about oven's ability to reflect accurate temp, procure a separate thermometer to sit inside so you can verify).

Remove and allow to cool for about 20 mins.

Reassemble board into computer simply following backwards along all steps. At this point you will be uber glad you laid all the screws out on a "map". Ha!

Presto!.... and 5 days later is still going fine. Better in fact.....

This is good. It means all the parts are talking to each other. So far all the ports are working fine, too. What's interesting is that the fans are not cranking up to high speed so often as they used to, so i imagine that has to do with the improved communications and heat draw-off via thermal compound.
