Unnamed Psilocybe with spiraling agar?
    #26352973 - 11/29/19 11:59 PM (4 years, 1 month ago)

Hello all,

I'm currently reading Paul Stamets last book.  It discusses all kinds of mushrooms and all sorts of applications. However there is one little part of the book that refers to an unnamed Psilocybe mushroom from California. Apparently when this particular species is cultured on agar, it grows in a spiral fashion and increases in speed as it grows.  Anybody know what species this is? I've got a picture from the book below.  If you have Mycelium Running, it's on page 8.

Probably contaminated plate lol. :shrug:
Or since he's a con artist he could have made the plate in such a way that anything would have grown in a spiral.

Also his supplements are trash
He won't give you lab results but thankfully some researchers did test commonly available mushroom supplements and turns out Paul's land last on the quality list

This is the species in the plate?  These occur where I live, maybe I'll be able to test it out myself eventually.

As for Stamet's credibility, I would agree he's not the most reliable source when it comes to specific mycological information.  I would not recommend his supplements to anybody either.  He does, however, have a lot of interesting ideas that are worth reading about and I don't know why he would make a sham agar plate for one little picture and description in his book.  Assuming it is real, I'm sure it's more of novelty characteristic then anything, but I thought it was worth the discussion.

Also if that's contamination, that's a cool as contam and I want to know what that is.  Might not even be mad if it took one of my plates.

Actually there was a similar thread 4 months ago
https://www.shroomery.org/forums/showflat.php/Number/26109067

and there's some research about it
Spiral growth of fungus colonies
Quote:


Spiral patterns of growth are sometimes encountered in the colonies of filamentous
fungi. Such patterns arise from various causes. For example an endogenous rhythm of
sporulation may produce a colony which forms an Archimedes spiral that grows usually
by one revolution for each cycle of the endogenous rhythm

Very interesting. Thanks Sporecap.

So it sounds like it's more of a mutation or due to environmental factors and not a specific species?  Stamets was a little misleading in his phrasing.

Quote:

Cultures of this yet-to-be named Calfornian Psilocybe mushroom swirl like a cyclone as they grow outward; the rate of growth increases with time.




It does kinda sound like he's trying to hype psilocybes with fake evidence. Kinda shammy.

It could be Coriolis-influenced rotational Doppler shift in atmospheric gases leading to low velocity standing waves of nonuniform oxygen availability across the mycelium perpendicular to the trajectory of growth. Cellular expansion becomes skewed in the more favorable direction, thus promoting growth that takes a curved path. The direction and radius of curvature would be further influenced by local conditions and geographic location.

I wonder what effect on mycelium if you spun a petri dish with an electric motor? Would centrifugal forces pull the strands out for accelerated growth?  :spun:

The most obvious explanation is often the correct one. :rofl:

The 1978 paper linked above actually has a nice explanation: the individual hyphae rotate "axially" as they grow, provided that they:
  • have unilateral support, such as growing on the surface of agar and not within a substrate or in the air
  • lack other stimuli -- if something is happening close enough to a hypha, even if it's just another hypha growing (and thus changing the nutritional/chemical environment around it), it reacts and stops growing as uniformly. A normal, dense colony thus doesn't display the overall spiral pattern as it requires a lot of hyphae growing & rotating uniformly.
So something in the way new cells are built causes a slight rotation that gets "corrected" in air but doesn't on a flat surface (presumably due to gravity/stickiness). Because of the "correction" it's probably some feature that evolved later? (It's not the clamp connection mechanism, at least not exclusively, as spirals occur in Ascomycota as well.)

Some sort of reaction-diffusion system between myc and contam?

I kept seeing Stamets name on here and then a couple days ago noticed he was on the rogan podcast so I checked it out. He does have a little douchey con vibe going on.
