I'm not sure if it's safe to let Cat play with the cordyceps. No future feeding those cultures!cordyceps-the-Last-of-Us.jpg

I can't get mine to fruit. Its been months. I put some charcoal In there which is the white you see as its now colonized. Went back and forth in different rooms to see if the temp dif would do anything.

Not sure where to go now.

Actual charcoal? Charcoal isn't activated and doesn't function like activated charcoal which is what you want if trying to induce pinning.

Many are confusing charcoal and even chard wood with activated carbon. Even camp fires do not get hot enough to activate the carbon or charcoal. There is no method that I know of for diy activated carbon/charcoal .

It's unclear exactly why activated carbon works and will very by species. In species that require a hefty colony of bacteria in the surface or casing to fruit properly, it is believed that the charcoal absorbs whatever the bacteria breaks down and consumes.

This reduction in what is probably a secondary metabolite containing hormones, triggers the species to fruit. As far as Cordyceps, they may or may not respond to the activated carbon as some species do.

What the charcoal is good for is a carbon source. Cordyceps enjoy a high carbon content and I'm talking more then 10:1 on the C:N ratio. High carbon subs will provide you the greatest yields with Cordyceps militaris and im going to speculate and say you didn't add charcoal to the substrate so doubt you will see a noticeable difference. There are other carbon source such as many of the 'ose' nutes. You don't have to use charcoal.

So on to your fruiting issue. Something I learned through my studies is not every Cordyceps militaris culture will fruit, even if it is of the same sub strain that has previously fruited. This could be what is going on if all your other parameters are in line.

How old is the culture? You have to get proven cultures into cold storage quickly after growing them out. I believe this to be best practice for any mushroom species but it is very critical for Cordyceps. Even sitting there at room temp for several days decreases the vigor of the culture. Cordyceps militaris loose vigor very quickly even a few transfers can leave you with a weak culture. Weak cultures are slow to fruit or may not fruit at all.

When you say months, how long exactly?

We have signs of life! This is the whole rice/eggshell jar (please note the Rad Mycology flyer, mad props!). The LCs have life too, but not enough to photograph.


How long from inoculation to first signs of life ?

Pretty nice bro . .
Found an related video

[Direct Link]

Very cool video. Looks like they were using a Tupperware type container filled with sorghum. Didn't look like there was a filter for gas exchange?? Maybe it wasn't needed. I have been experimenting with C. sinensis and using sorghum. Never had luck getting fruits, but never added larva. I did get cakes of mycelium harvested from a broth. dried then run through a coffee grinder and put in jell caps.
Looking forward to seeing results Cat, keep posting....... Cool thread.

Does the mycelium have the same or similar proprieties of the fruit body ?

The mycelium changes color sometimes to that bright orange. My last run triched out.

Mold loves attacking it.
