Greetings! This thread will document my first attempt at fruiting a commercial strain of Cordyceps militaris. I see a lot of people try to run this species and fail or give it the 'fade away'. According to the book muskie suggested on the cultivation of Cordyceps, this is less about the skill of the cultivator than the viability of the culture(s). Apparently, with cordyceps, senescence happens quickly. Once it does, it will never be able to produce spore bearing fruit bodies. That is issue #1. Issue #2 is that "C. militaris behaves as a bipolar heterothallic fungus and requires two mating compatible strains in order to produce regular club shaped perithecial stromata." That last one explains a lot. I've traded/purchased many cultures from different sources and none of them showed the slightest inclination to produce mushrooms. Initial inoculation will be from a liquid culture syringe from the author of the creatively titled book I'm referencing: Cordyceps Cultivation Handbook. I chose the Cordyceps PMA5 culture because...5 is bigger than 4? Actually it's because I've seen others who possess the PMA4 and I hope to do future trades with them. The substrate will be this simple recipe which has already proven itself to be infinitely more suited to cordyceps than my grain/gypsum jars: Basic Media Recipe 3 cups of Grains (Rice, Millet, Local Wild Grass Seed, Popcorn) 6 cups Water 2 tbsp Sucrose 1 tbsp Corn or Potato Starch 1 tbsp Yeast Extract or Nutritional Yeast (Nitrogen Source) 1 tsp Azomite My purchased, guaranteed 'fruiting capable' LC goes directly into this mix, colonizes and fruits in the same container. EZ peesy. Assuming all goes well and I get mushrooms, I will immediately start collecting and germinating spores to create viable intraspecies crosses capable of reproduction. In the meantime, comparison photos of grain/gypsum spawn inoculated 1.5 months ago, colonization was slow and weak but has finally consolidated as much as I think it's going to. You can see it doesn't care much for the hull of the whole oats: Compared to these jars, prepared according to the above recipe, inoculated 5 days ago, g2g from one of the above jars (subbed potato flake for potato starch, that's what carmelized on the sides of the jar): A bit closer, you can see the oats I transferred are still poorly colonized while the brown rice buffet is clearly open and quite popular. So, just to be clear, this is a rando culture obtained from a dude on facebook. There's no evidence it is a viable fruiting culture. In the book, the author states that if your culture sits around for much more than month without fruiting, it isn't likely to, so I think I can write this one off. My new culture will be here in 3 days- according to the tracking # and, of course, weather willing. I will start with the 'blow by blow' as it happens, from inoculation to success or failure. Let's find out if I spent $40 bucks wisely or on another dead end.
