Interesting shroom teaser for the experts...
    #6468949 -

Not sure where this should go, but is probably of most interest to the peeps here so mods please leave t for a bit, thx! Its from a book I got for christmas, you can possibly find the answer on the net, but first I would like to see if anyone knows. I will post the answers I have tomorrow.....

Near where I live there are toadstools growing through the pavement, the surface of which they have displaced in fairly large chunks. What mechanism allows toadstools-essentially very soft and squashy items-to push through two inches of asphalt?

A crack in the pavement?

No crack in the pavement, they can actually rip it apart! But how?

As soon as a crack forms water is going to fill that void... as you all know water has a great capacity to expand when frozen, which can exert amazing forces upon any material that is currently retaining the moisture. It can also soak into suitable material causing it to swell, which would in turn exert these previously mentioned forces. This is how the blocks for the base of the Temple Mount were extracted from the quarry, by placing a series of large beams between two faces of the block and soaking them with water to create enough force to wedge the stones loose.

I would presume that a few seasons time has passed since the beginning of these cracks and the appearance of the mushrooms. Therefore, the mycelium didn't actually produce the cracks themselves as much as they simply fruited in a close vicinity to their supposed origin.

Think about it, if mushrooms could do this... who is to say the healthiest rhyzo's wouldn't shatter through your PF Jars and start consuming your house? Now that would be quite a site to see... I think they made a movie about it... The Blob? :laugh:

I'm imagining that it's a form of hydraulic pressure.... going along the lines of the fact that water can't compress (easily).

Just a guess.

Damn right! Well done.

Check back for full explanation, it's impressive.

Two inches of asphalt is nothing to the muscular mushroom! One large shaggy ink-cap (Coprinus comatus) discovered in Basingstoke lifted a 60 by 75 cm paving stone to 4 cm above the level of the pavement in 48 hours! Historically mushrooms often sprung up in foundaries, supposedly from horse manure used in preparing loam for casting, and were often reported as having lifted heavy iron castings! Presumably these would have been some type of field mushroom such as Agaricus campestris. Whatever the species, the mechanism by which the force was exerted is likely to be the same, hydraulic pressure. As Buller found (see next post), the exquisite and fragile Caprinus sterquilinus exerts an upward pressure of 250g from a stipe of only 5mm thick! Hardly suprising a more robust shroom can tear tarmac apart!

You would think if a mushroom could break concrete, a glass mason jar or plastic fruiting chamber would be no match...

Yeah, you really should!
Be quiet and nice to them and always give them what they want.
They are kind of choleric, although their bouts are pretty slow!

i've had tall ones push and eventually lift the lid right off small fruiting chambers before... once the lid gets open though things go dry, time to pick 'em at that point

they probably don't bust out of a glass jar grown in-vitro because everything is contained to begin with, you're just "converting" the substrate material into mushrooms, not adding or subtracting, so as "food" gets digested, room is made for the developing fruitbodies... its a path of least resistance thing, they'll squish up the substrate long before they break the glass

you arent thinking about the tensile strength of plastic vs concrete. plastic will elastically deform (without any perminant deformation). but the concrete, being very brittle does not have a yield point, and do not strain-harden which means that the ultimate strength and breaking strength are the same.

it can be easily seen on a stress-strain graph.
