Wtf? Straight vertical shiitake mycelium growth...

Ok, what the heck is going on here... Been doing a little experiment. Placed two Shiitake plugs from my supplier a ways away from each other on top of a quart of sterilized Red Alder sawdust (Supp +20% Oatmeal) and one of them is behaving strange...

The other six jars with their two plugs have normal cottony mecelium like the one on the left. The one acting strange has the red arrow pointing toward it. Anyone got any ideas? Mutant plug? Worlds smallest Shiitake mushrooms with caps the side of pinheads? Looking closely, it also has normal cottony mecelium spreading from it too...

looks normal to me, usually any mycelium will do that when it's trying to find food. But since there's no food up there, it reaches as far as it can. if you buried it in the substrate a little it wouldn't do that as much. It's just finding its boundries, you should see some king oyster I had in a bag, it did that but it went up almost an inch off the sawdust.

It's an inch and climbing... None of the other plugs did that and most of them are mostly on the surface and not as pressed in like that one was.
Also, the mecelium is much finer and cottony on every other plugs. It also never reached more than 1/3rd of an inch vertical. Moisture condensing on the other mecelium each day appeared to pull it down.

Btw, if it is mycelium growth, what are the little pinhead sized things on the tops of that tall stuff?

That looks a lot like a Rhizopus/Mucor species, maybe some other zygomycota like Phycomyces.
In other words it looks a lot like a contaminant i'm afraid.

I am definitely not happy if it is a contaminant. Do the mycelium of Rhizopus/Mucor species look black?
I noticed some odd black looking areas in my grain spawn and black stripes on a few plugs. (Along the grain.) Ill open up that jar and extract that plug for analysis once it is a bit grown over. Don't want to risk contaminating the jar with mold opening it before the top area is fully colonized.

It could also be one of the dactylium species, generically called cobweb. That doesn't look like shiitake mycelium, so keep an eye on it. RR

Shortly you will start seeing small black dots on the tips. Hopefully I’m wrong!

There already is dots on the tips... Brown though, not black yet! Arr... Screw it, I am extracting that plug for analysis!

Phew... It wasn't near the other plug. Thank god! (Plug spawn isn't contaminated!) In the sunlight those dots on the tips are black. I pulled the stuff up... I'm kinda curious if the Shiitake can still make it. It appeared to be growing around it.
