"Mission to Blue Grannus" Novel Update

The most consistent thing readers of Green Tara have said is, "When can I read the next one?" And indeed the novel was always meant to be the first in a trilogy. Now, I have a follow-up novel that should be ready late this year. 

The setting for Mission to Blue Grannus is inspired by ice caves that form during high winds and deep freezes. These conditions occur here on Earth on Lake Michigan and Lake Superior, where waves freeze solid and swells become ice caves. 
This new one, Mission to Blue Grannus, picks up two years after the end of Green Tara, when the pirate twins invite Gordy, now 15, to join them in a rescue mission. The pirate ship arrives at the edge of the Grannus system soon after his family. They're avoiding a Triumvirate engineering crew sent to reopen a toxic mine on the blue ice moon. 

The Grannus System was at a crossroads. The outer ring is volatile, with a crack in dimensions that offered a faster than light pathway to a network of destinations, including her mom's last known location, and they needed to find her. 

Also, the crossroads was about power and who controls the land and water. On Blue Grannus the original mine had closed decades ago, leaving the miners behind, abandoned refugees. One faction of the refugees lives deep in the blue ice caves, where the mushroom man cultivates strains of mycelia to myco-remediate the moon's toxic water. 
For more stunning landscapes that inspired my story world for this part of Gordy's journey, see these photos by Heather Higham.
The scientific inspiration of Blue Grannus comes from world mycology expert Paul Stamets. I saw his TED talk "How Mushrooms Can Save the World" and immediately understood the implications of his research for repairing damage to our Earth, and also for my sci-fi future vision of human terraforming and myco-remediation efforts. So, just as book 1 was inspired by invisible, essential phytoplankton in the ocean, book 2 is inspired by invisible and essential mycelium networks, the underground rootlike systems of the Fungi Kingdom, and the myco-remediation action of those networks. 

In my story world on the Blue Ice Moon orbiting the gas giant of the Grannus System, the Trivert mining engineers are starting up tests again. Orders from the board were to apply new techniques in the extraction process to yield gold and other precious metals, even though these new methods would put human  refugees at further risk by unleashing even more toxic chemicals into their water system. Gordy and his cousin Virginia, my teenage eco-warrior heroes, volunteer to help the pirates and the refugees make a trade that will protect their myco-remediation efforts. 
The power of mycelial networks to remediate poisoned water is a perfect fit for Mission to Blue GrannusFrom Radical Mycology, here's a clear 1-page overview of myco-remediation: https://radicalmycology.com/educational-tools/human-uses-of-mushrooms/mycoremediation-101/
Two years ago, to understand more of the considerations, I put on my literary scientist hat and took a deep dive into all things mycological. I grew oyster mushrooms from a patch, bought the book, and took a weekend seminar Mycelium Running, by Paul Stamets. To the best of my ability I have marinated the entire story with what I learned with him and his team at Fungi Perfecti.

When I do classroom visits with Green Tara, the fifth and sixth graders are thrilled by the adventure, in which the main characters take action steps to regenerate bio-systems. I'm looking forward to taking Mission to Blue Grannus to the classroom, as well. 

We all need action steps, a game plan, for our land and water are under assault locally and globally. The question I try to answer in this series is How can we repair the damage humankind has wrought on our beautiful planet?

Oyster Mushroom Report 4 of 4:
Two More Clusters

Last week I left you with a real cliff hanger: after I harvested one cluster from my second flush, I saw emergent growth in a handful of clusters around the edge of the bucket.

Day 9 - primordia emerge from clusters that did not thrive in the first flush

Could I keep them happy enough to thrive, or would they shrivel and die in the summer heat or air conditioned air, or suffer oxygen deprivation from life under a humidity tent? There are several variables to consider when growing mushrooms outside a perfectly controlled, lab environment.

Day 10 - No guarantees, but hopeful growth.

Some days I carried the bucket back and forth, into my living room during the heat of the day and out to the screened-in deck for moist night air.

Day 11 - Cautious optimism is in order. The new growth has outpaced the fruit that did not thrive in the first flush.

Two of the five clusters in this third flush continued to thrive. Three did not.

Day 12 - Graceful formations in two clusters.

In the second flush I think I harvested a day too soon, before the outer edges arch upward.  (I'd been frustrated by the coral formation of the first flush and was impatient.) This time, I waited patiently.

Day 13 - The edges never arched upward -- apparently drooping in the heat.
This time I may have harvested a day later than prime, as the outer edges thinned and lost their hearty texture. Regardless, the results were pretty spectacular. Here they are ready to saute along with onions, potatoes and peppers. My son and husband approved of our Labor Day weekend supper.

The dark coffee grounds on the base of the clusters on the far left and top right, help show the growth pattern of a cluster of oyster mushrooms. 

I'll let you know if there's any more action in the bucket. Right now it's at rest, and I'm letting the bucket dry out. 

Meanwhile, I need to get back to a scene in Mission to Blue Grannus. Gordy and Virginia are preparing for their trek to the blue ice caves, where they hope to find the mushroom man.

Oyster Mushroom Report 3 of 4:
Second Flush is a Success

Day 1 - first flush of fruit 

One month after I inoculated coffee grounds in a bucket with healthy mycelium, 5 days after I trimmed back undesirable coral growth and gave the bucket more air by using the tent less and moving outside of the drying air-conditioning, I finally spot emergent mushrooms. These are a much healthier shape than the coral growth I saw last week. 

I'm calling this first siting Day 1.

I captured these tiny primorida using a macro lens.

Day 2 - rapid growth using regular iPhone camera lens

Day 2 - rapid growth


Here I'm pointing to the same cluster pictured above.

Day 3 - continued growth

The next day the growth rate slows a bit. 



Day 4 - close to harvest

The ideal shape for picking is just as the caps uncurl and reach upward creating a funnel shape, and before they flatten out too much.

Morning light on thriving oyster mushrooms. By evening they were ready to harvest and it was dark and I was hungry, so there's no picture of me sautéing these with garlic. Yummy.
Day 5 - after the harvest

At the same time the cluster pictured above had grown, I spotted another handful of clusters begin to emerge. I had high hopes that I'd enjoy a series of small flushes. 

I didn't think it would help to keep them inside for any length of time, because the air-conditioning would dry them out and the humidity tent seemed to starve them of oxygen. So I took the bucked outside.  

Unfortunately, the summer heat got extreme, rising to 90 degrees in the midday, and those temps are not most conducive to oysters. My hopes of more culinary delight were dashed as I watched them start to shrivel.

Day 8 - shriveled clusters

Disappointing, to say the least

Day 8 - 2 of 5 clusters - apparent failure to thrive
Day 9 - what next?


This morning, I was thinking about what I could do to coax more activity from the mycelium patch I've created, and look what I found: fresh emergent growth!

Day 9 - white emergent growth appears around the clusters that didn't thrive. 

I'll let you know what happens next week.

Oyster Mushroom Report 1 of 4:
How to Inoculate Coffee Grounds

Clusters of primordia surfaced yesterday, one month after I first inoculated the substrate of coffee grounds. Here each of the mushrooms is less than .5 centimeters in diameter. Today they're at least twice as large and, if all goes well, they'll continue to grow rapidly.

To inoculate your substrate (in my case coffee grounds, but you can use other growing mediums), the absolutely first thing you need is to secure your oyster mushroom spawn with mycelium running throughout. My spawn and how to knowledge came from Fungi Perfecti. (They are my go-to resource, and I'm simply showing you that anyone can do this.) There are other commercial sources for mushroom spawn, as well.

These are the supplies I used:
  • 5 gallon plastic bucket 
  • 4-5 pounds of used coffee grounds to use as the substrate/growing medium - free from my local Starbucks, so a very urban/suburban option (Note: If you don't use the grounds right away, you can freeze until you're ready so they don't get skanky.)
  • disposable gloves - wear whenever touching the inside of the bucket or any of the spawn or substrate (coffee grounds)
  • rubbing alcohol and a clean rag
  • oyster mushroom spawn 
Once you have all your supplies, start by preparing the bucket. Drill air holes near the top for air and in the bottom for drainage. (I set the bucket on a large saucer and both atop a stool, so I can easily move my experiment, as needed, to optimum light, temperature, and humidity.) 

The day of inoculation:
  1. Sterilize your bucket with soap and water, then a final rinse of rubbing alcohol. (Remember to wear gloves and/or sanitize your hands with the alcohol before touching the clean bucket.)
  2. Pasteurize your substrate. (I boiled used coffee grounds in non-chlorinated water for 30 minutes and let cool before pouring into my bucket.) 
  3. Mix the coffee grounds with the spawn.



Wait for the mycelium to colonize the bucket. In my case, I saw the first signs of healthy growth in five days.



Wait some more. 

Depending on your results, adjust conditions. In my case, it took a full month from inoculation to seeing mushrooms beginning to fruit. (Last week I showed you what happened when my first flush of oyster mushrooms sprouted in an undesirable coral formation. So, I removed the coral and the plastic humidity tent to provide more oxygen and misted the surface with a diluted hydrogen peroxide solution to treat suspicious, possibly competing green mold.

I'm finally getting good results. Fingers crossed. I'll take pictures every day to record mushroom progress and report next week!

Oyster Mushroom Report 2 of 4:
Overnight Growth is Coral-shaped

Oyster Mushroom Bucket Experiment
This morning I was aghast to find my oyster mushroom bucket experiment and, when successful, culinary treat had grown coral-shaped formations overnight.

My first flush of mushrooms doesn't have enough flesh to make a meal.

Coral-shaped formation--elegant shapes, but undesirable for an oyster mushroom.
This undesirable coral formation has one of two causes:
  1. not enough light
  2. not enough oxygen; too much carbon dioxide
I've had the oyster mushroom bucket in a western facing bay window, where it gets ample indirect light--ideal for this method of propagation. So, I deduce that the cause is not enough oxygen.

I was using a plastic tent to keep the bucket humid. Though I have ventilation holes and three times a day pull the tent off to let the carbon dioxide escape, I deduce I needed to give the patch more time to air each day.

Oyster Mushroom Bucket -- Out for Fresh Air
The weather is perfect today--70 degrees F and raining--so I took the oyster mushroom bucket to my screened in porch. I plan to trim the coral formations and hope for a second flush of edibles.

Pale Green/Gray Mold
Note: Even the coral doesn't grow here.
Near three of the air holes--where I may have carelessly touched the patch to clear coffee grounds away from the hole--first indications of mold appeared today. This is another undesirable development in my experiment, but easy to correct. In the past, light, regular misting of a mild hydrogen peroxide solution has worked for me.


The three steps I plan to take to encourage a second flush of healthy Oyster mushrooms:
  1. give the patch more fresh air
  2. trim the coral back to the mycelium
  3. spray the green mold with hydrogen peroxide solution 
In my next report, I'll give the steps I took to inoculate coffee ground substrate with the spawn I prepared in a June seminar led by Paul Stamets: Mycelium Running: How Mushrooms Can Save the World.
