Getting Penis Envy to Print
    #11254318 - 10/15/09 06:01 PM (8 years, 1 month ago)

hello all.
Getting Penis Envy to Print
looking to actually find a consistent way to get this to happen.

1. why don't they drop spores like regular?
2. is there a physical or biochemical reason? anyone with a microscope who routinely looks at prints for I.D. could help here. Workman are you there?
3. could they be induced through other than normal means to drop the spores instead of using swabs all the time?

let's give it some thought and see what we can do to help ourselves.

here is an interesting video on spore drop.Spore Drop video


here is a quoted message and i'll provide the link too.

Spore Discharge


Quote:

The discharge mechanism
Now it is a simple matter to explain the way in which the spore gets off the gill and away from the mushroom cap. The following diagrams illustrate the first part of the process (ejection from the sterigma) and the explanations follow.


1. Between the gills the air is still and very humid. At the point of the apiculus the spore secretes a small amount of sugar molecules. If you've ever left an open sugar bowl on a kitchen bench for a lengthy time, you would have come back to find that the sugar had picked up some moisture from the air. Sugar is an excellent absorber of water vapour. Given the surrounding high humidity between the gills, water condenses onto the sugar at the tip of the apiculus and forms a drop (the small, solid, greyish-blue circle). This drop is known as Buller's drop. At the same time a thin film of water forms on a large area of the spore surface and this is represented by the brighter blue layer over much of the spore outline. The growing drop leads to a significant increase in mass at the apiculus, thereby causing the centre of mass to move towards the apiculus, as shown by the red arrow.



2 and 3. The water drop continues to grow in size as more water vapour condenses onto the drop's surface. This draws the centre of mass well away from its original point. Eventually the drop grows large enough to come into contact with the film of water on the spore surface. The contact point is arrowed. The drop may grow quite large in relation to spore size.

4. As soon as the drop comes into contact with the film, the drop collapses, with the water in the drop flowing into the watery film. This happens very quickly and the centre of mass moves very rapidly in more-or-less the reverse direction (as, again, shown by a red arrow). Simultaneously the spore is given considerable momentum, there is a break at the weak apiculus-sterigma boundary and the spore accelerates along the axis of the changing centre of mass (so moving off in the direction shown by the black arrow).

There is an excellent, explanatory 10.5 minute videotape, Ballistospore discharge in Basidiomycetes, with scientific direction by John Webster (who was instrumental in discovering the nature of the water-drop mechanism described above). The video is available in English and German language versions from: IWF Wissen und Medien gGmbH, Nonnenstieg 72, D-37075 Göttingen, Germany.
To give you some idea of the difference in speed, steps 1 to 3 are analogous to someone slowly stretching an elastic band and then, in step 4, the elastic is released so that it returns to its original size almost instantaneously. The momentum generated by the collapsing water drop is enough to give the spore an acceleration of 25,000 times the force of gravity. By comparison the NASA Space Shuttle has a maximum acceleration of just a few times the force of gravity. The spore loses about 1% of its mass in the secretion of the sugars on the apiculus. To continue the rocket comparison, the Space Shuttle uses about 50% of its own weight in fuel during the first two minutes after launch





if anyone is having trouble streaming these let me know.

1. cuz they're broken
2. Yes.
3. Hopefully.

That link was some really good reading. The video page is in german or something and costs money?

let's look at part of the first part of number 1 above :

so at this point we seem to have biochemical/biophysical forces at play. the whole mechanism although mentioned is not really explained. for instance, what causes the Buller's drop to form in the first place? go a step further and pretend that the PE doesn't do this because of some mutation. now someone with a scanning microscope like they use on the site mentioned above could actually really tell if this is happening if the PE fungi were studied. of course, for us, it may be mostly academic because of the nature of our beast. most people can't legally do these experiments with this fungi to further science. but it is interesting nevertheless and may lead us to experiment empirically, like edison did to find the right filament for the light bulb.

for anonjon and others. the link is embedded in an .asx file that you download. you just have to manipulate the first part of it. the language is english.

Heres another link discussing this in detail.
http://blog.mycology.cornell.edu/?p=425

The problem that I see, is that it's highly unlikely u can induce the spore to produce the sugar necessary to make the bullet drop form. It would have to be produced by the spore at the correct location for the drop to occur.

Let's say there was some substance that would induce the spore to do this; what are you going to do, spray it under the gills?

Printing the cap like a stamp is not a bad option. Neither is gill irrigation or cotton swab. Only downside is that you need to start with agar, cuz there's no guarantee you're getting a sterile sample. I did a q-tip swab to agar and got a clean sample on the first try. It's really not that big of a deal.
