How do shelf mushroom species "know" how to orient their fruiting bodies?
    #21883250 - 07/01/15 03:03 PM (8 years, 6 months ago)

I’m assuming this would be the correct place for this post, but if not I apologize.

The other day, I was walking barefoot along a black cottonwood tree weakened and brought down by a mycelial infection.
As I plodded along the log, enjoying the texture of dead bark on my naked feet, I noticed the shelf mushrooms that protruded out of the fallen tree somehow knew to grow as shelves, tops to the sky, bottom to the ground; despite the tree having fallen and the position in which they once made these fruiting shelves having changed.
(Hopefully the way I worded this makes sense, I’ll clarify if not.)

Thus, began my fruitless search for any information on how the mycelium knows, or is triggered to do this.
Does anyone here know how the mycelium “knows” how to properly orient its fruiting bodies in this fashion?

It could be gravitationally oriented, but I assume it would be the way the light hits it, making the mushroom grow so that the light shines onto more surface area than if it were sideways.

Those were the two possibilities I thought as well!

Just can't find anything on the subject to confirm or dismiss it... :frown:

Gravity may play a part in it, but I know that the major orientation sensor for most fungi is light, specifically in the blue wavelengths. It varies a bit, but most fungi use some variant of the gene wc1.https://en.wikipedia.org/wiki/White_Collar-1

Most often you find it written about in the context of its circadian rhythm function, but its tied into a ton of other pathways.

Very sorry if this is the wrong place for this but I am new to forum and can't for the life of me figure out how to make my own post and really need some advice.

To make this short, SWIM has a garden and their friends family has a giant cow manure compost pile.  SWIM took a few chunks of this compost to use as fertilizer for their garden and left them in the car for a couple days.  Today SWIM said he took them out of the car and was breaking them up and spreading them at the base of his plants when he noticed some white pins with golden centers popping up from one of the chunks. SWIM is wondering what he can do to further encourage growth of these pins. Would it be wise to leave them in humid greenhouse or will light destroy these little ones? I can't identify them yet but hope to when they grow up. Thank you for any information that you are able to provide

Go to community>message board> mushroom cultivation, you'll see "post" at the top right of all the threads.

Also no SWIM, we all know it's you

Yes! Both these links are exactly the sort of thing I was looking for. Thank you very much! :thumbup:

I actually did a massive term project on photoperception amongst fungi last semester, so I happen to have a few links handy :tongue:


If you'd like more info, this paper is a fantastic primer on the subject:
www.iab.kit.edu/microbio/download/2010_Rodriguez_et_al.pdf

Its mostly general info, and mostly focus on the ascomycota, but you can extrapolate from there if you want. Have fun!

gravitrophism

plants do it and i reckon mushrooms found a way too.

i have found conks on fallen trees that have sprouted smaller conks perpendicular to the original ones that were growing when the tree was vertical.  have you observed this too?  if not i will post pics.  pretty cool stuff.

Yep, I've seen that but it may be that light is also a factor.

Light,  gravity,  and air currents all affect the orientation
