We wrote recently about saving seeds and finding local folk to swap seeds with.
You know what you rarely see at a seed swap? Spores.
I think that's because many more people grow plants than mushrooms. And we don't have the culture around mushroom growing we do around plants. We'd like to change that.
Just as our plant crops have been shaped over countless generations of humans tending, selecting and breeding plants, fungi too respond to human participation.
People in fungi-loving cultures learn where the family patches are and how to keep them healthy and abundant. When people select the strongest, largest or most delicious specimens in the forest then carry them home they become part of the fungi's spore dispersal strategy. With every step the mushroom hunters are potentially spreading spores around.
Chris doubled the size of one of our lobster patches in a few years by cutting the stem butts where he harvested the mushroom then retuning them to the soil, under the leaf litter, a few feet away. He did it consistently every time he harvested and now we have more lobsters than we can eat each year - the insects, rodents, turtles and other forest dwellers get to eat their fill too.
Mushroom cultivation gets very interesting when you learn to work with spores. Chris likes to take spore prints from mushrooms he finds in our woods, or close by, let them grow into mycelium on petri plates then select the mycelium that looks the strongest to make into spawn and eventually let fruit into mushrooms. Then we are working with hyper-locally adapted strains that know exactly how to thrive right here.
How he can tell which are strongest by looking at a petri plate is a whole other story!
Part of the vision we hold is that there are mushroom labs across the country, around 200 miles from each other. Each lab is breeding strains of locally adapted mushrooms, selecting for those with great taste, medicinal properties or growth characteristics, then sharing them with other cultivators.
We see these labs becoming culture libraries and nodes in the mycelial network keeping spores alive, vibrant and always abundantly available for anyone who wants to grow.
When I say "lab" this isn't some high-tech thing. We built ours in an old woodshed. We poured a concrete floor (by hand), used some corrugated metal on the ceiling and walls, and put linoleum on the flour. We can keep it clean. We have some basic lab equipment that doesn't cost much. It works just fine.
This is one way we can become partners with fungi. They feed us, we help them expand. We get to be part of their cycle as they get to be part of ours.
A first step? Take a spore print. It's an easy way to get a look at some spores. You can find the instructions on our YouTube.
From there you can gift them to your favorite mushroom geek (!) or learn to grow them out on cardboard which you can then expand into spawn and grow mushrooms.
We cover this in both our online Start Growing Mushrooms course and our day-long, in-person, Backyard Mushrooms (next one is November 7th).
