Trichoderma part 2: wiping it off won't help? It will stop the spreading! Photos from the Pallets

Mold can also be green or blue. Wiping off the mold won’t help your log, but the mold may not prevent fruitings.

This seems disingenuous.  The green mold is the spore formation for SPREADING the mold! It would seem that wiping it off would stop the spreading!

 the green is mold spores, spreading everywhere.

Well, the green mold likes the same environment as the fungi,” he said. “Most people freak out about it. But it’s natural. Just soak it for 24 hours in water with a little bit of bleach.” How much bleach? “Half a capful for every three gallons. Then take it out and wipe off the mold.”

hmm. Do I really need bleach? Again it seems just "wiping off the mold" will at least stop it from SPREADING!!
“The molds flourish in the same environment as the mushrooms,” said John. “Try scraping it off again, putting it in a brand new bag, and letting it rest for two or three weeks.”
Resting for a mushroom log means being wrapped in the bag rather tightly (to discourage the mold) and being left alone.
Exactly - just get rid of the stuff. 


 Asexual sporulation occurs as single-celled, usually green, conidia (typically 3 to 5 µm in diameter) that are released in large numbers.

  In nature one can often find Trichoderma parasitizing the fruiting bodies and mycelia of other fungi, such as the fruiting body of Hydnochaete to the left. Trichoderma is a particular problem in the mushroom cultivation industry, where it can parasitize the mycelium and fruiting bodies of the fungus. This is known as green mold disease of mushrooms. When the mushroom is parasitized, it develops a green mold over the surface, making the mushroom ugly and deformed. When the mycelium is parasitized, the ability of the cultivated mushroom to grow is severely compromised because the mold saps it strength, benefiting from the hard work of the mushroom's exoenzymes to degrade the substrate.

 I have used trichoderma infested spawn to make successful projects before. They almost always showed trichoderma on or after the second flush. This was out of neccessity. I simply washed off the infected portion and crumbled to spawn.
 This being in addition to realizing that trichoderma is common in many soils from things such as peat........It is typically understood that periods of high humidity and low-no air exchange (and subsequently high co2 due the the low air exchange) will allow trichoderma an advantage on the substrate allowing it to colonize....
